I really like this idea, but I get distracted when the vertical bars don't line up! +--------+ | | | ASCII! | | | +--------+
damnitbuilds 8mo ago
Nice ! Very true that if you, for example, show a group a button with a given color, they will waste the meeting discussing the color and not what the button should do, so ASCII is a nice way to not have to do that.

This is a tangential point (this post is not really about TUIs; sort of the opposite) and I think lots of people know it already but I only figured it out last week and so can't resist sharing it: agents are good at driving tmux, and with tmux as a "browser", can verify TUI layouts. So you can draw layouts like this and prompt Claude or Gemini with them, and get back working versions, which to me is space alien technology.

  Would love to hear more about this approach.

    It's actually really easy in Claude Code. Get a TUI to the point where it renders something, and get Claude to the point where it knows what you want to render (draw it in ASCII like this post proposes, for instance). Then just prompt Claude to "use tmux to interact with and test the TUI rendering", prompt it through anything it gets hung up on (for instance, you might remind Claude that it can create a tmux pane with fixed size, or that tmux has a capture-pane feature to dump the contents of a view). Claude already knows a bunch about tmux. Once it gets anything useful done, ask it to "write a subagent definition for a TUI tester that uses tmux to exercise a TUI and test its rendering, layout, and interaction behavior". Save that subagent definition, and now Claude can do closed-loop visual and interactive testing of its own TUI development.
    - electroly 8mo ago
      Can you explain tmux's contribution here? I'm confused why this process wouldn't work just the same if CC directly executed the program rather than involving tmux. Are you just using tmux to trick the program under test into running its TUI instead of operating in a dumb-stdout mode?
      - tptacek 8mo ago
        It allows Claude to take screenshots and generate keyboard inputs. It's like TUI Playwright.
        mrstackdump 8mo ago
        Maybe I'm not understanding it (totally possible!) but could Claude just do that by reading standard out and writing to standard in?
        tptacek 8mo ago
        I had a really hard time getting anything like that to work (you can't just read stdout and write stdin, because you're driving a terminal in raw mode), but it took like 3 sentences worth of Claude prompt to get Claude to use tmux to do this reliably.
        mrstackdump 8mo ago
        I would love to see your prompt if you ever post it anywhere.
        _sinelaw_ 8mo ago
        For Claude, it's enough to prompt "use tmux to test", that usually does the work out of the box. If colors are important I also add "use -e option with capture-pane to see colors". It just works. I used it regularly with Claude and my TUI. For other agents other than Claude I need to use a more specific set of instructions ("use send-keys, capture-pane and mouse control via tmux" etc.) Since I have e2e tests, I only use the agent for: guiding it on how to write the e2e test ("use tmux to try the new UI and then write a test") or to evaluate its overall usability (fake user testing, before actual user testing): "use tmux to evaluate the feature X and compile a list of usability issues"
- agavra 8mo ago
  This is spot on, I understand very little about how terminal rendering works and was able to build github.com/agavra/tuicr (Terminal UI for Code Review) in an evening. The initial TUI design was done via Claude.
- frumplestlatz 8mo ago
  I’ve actually got an MCP server that makes it really easy for Claude to generate key events, wait for changes / wait for stable output / etc, and then take PNG screenshots of the terminal state (including all colors/styling) — which it “views” directly as part of the MCP tool response. Wish I could open source it; it’s a game changer for TUI development.

  I've had a lot of good luck with AI Agents also being able to read and meaningfully interprete .txt and .ansi dumps from RatatuiRuby's TestHelper module and its `assert_snapshots` [0]. For example, it was able to read the ANSI and figure out that a snapshot had changed because an upstream bug properly rendered bold and underline when it hadn't before.

jlundberg 8mo ago
Neat concept and very inspirational. Is ascii/unicode text UI the way to go here or is there other UI formats even more suited for LLMs?
- kmoser 8mo ago
  LLMs are surprisingly good at extracting data from other data, so at the end of the day there is no right or wrong, it's what works best for you use case.
- ehsanu1 8mo ago
  It has to be suited for human consumption too though. I wonder if this has any real benefits over just doing very simple html wireframing with highly constrained css, which is readily renderable for human consumption. I guess pure text makes it easier to ignore many stylistic factors as they are harder to represent if not impossible. But I'm sure that LLMs have a lot more training data on html/css, and I'd expect them to easily follow instructions to produce html/css for a mockup/wireframe.
ucarion 8mo ago
It is news to me that manipulating ASCII art is something AI can do well! I remember this being something LLMs were all particularly horrible at. But I just checked and it seems to work at least with Opus 4.5. claude(1) with Opus 4.5 seems to be able to take the examples in that article, and handle things like "collapse the sidebar" or "show me what it looks like with an open modal" or "swap the order of the second and third rows". I remember not long ago you'd get back UI mojibake if you asked for this. Goes to show you really can't rest on your laurels for longer than 3 months with these tools.
mixmastamyk 8mo ago
Like the idea, but this is definitely Unicode and not ASCII. It's hard to believe someone finished a piece of this length but still misunderstood, especially when some examples have emoji in them. Alternately, they chose a misleading name on purpose. Why? Someone mentioned TUI, which sidesteps the issue entirely.
- kmoser 8mo ago
  You're technically right, but I think that's a minor quibble. They could have indeed limited it to ASCII (7-bit if you really want to be a purist) and everything would still work just as well.
- ehsanu1 8mo ago
  It kind of makes sense if you relate it to ASCII art, which is very often not ASCII for similar reasons. The naming evokes that concept for me at least. Naming is hard in general, I'm sure they tried to find a name that they thought worked best. I agree that "TUI" is a better fit though. But not TUI-driven-development, more like TUI-driven-design, followed by using the textual design as a spec (i.e. spec-driven development) to drive GUI implementation via coding agents.
- batisteo 8mo ago
  I totally agree. It's called Plain Text.
calufa 8mo ago
Author here. High-level: - Problem: AI UI generators are high-fidelity by default → teams bikeshed aesthetics before structure is right. - Idea: use ASCII as an intentionally low-fidelity “layout spec” to lock hierarchy/flow first. Why ASCII: - forces abstraction (no colors/fonts/shadows) - very fast to iterate (seconds) - pasteable anywhere (Slack/Notion/GitHub) - editable by anyone Workflow: - describe UI → generate ASCII → iterate on structure/states → feed into v0/Lovable/Bolt/etc → polish visuals last It also facilitates discussion: - everyone argues about structure/decisions, not pixels - feedback is concrete (“move this”, “add a section”), not subjective More advanced setups could integrate user/customer support feedback to automatically propose changes to a spec or PRD, enabling downstream tasks to later produce PRs.
- 4b11b4 8mo ago
  While I agree a text representation is good for working with LLMs... most of the examples are mis-aligned? Even the very first one (ASCII-Driven Development) which is just a list. I guess this is a nitpick that could be disregarded as irrelevant since the basic structure is still communicated.
- NetOpWibby 8mo ago
  The problem with ASCII-driven development for me is that emoji ruin the alignment. It’d be nice if they could be forced into monospaced. Emoji aren’t ASCII so maybe that’s the problem too.
  - manquer 8mo ago
    Unicode emojis aren’t ascii . Long before Unicode points were assigned we were using emojis in text communication in email and sms. you can always be quite expressive with ones like :) :D :-( or even ¯\_(ツ)_/¯ - although not strictly ASCII.
    - Izkata 8mo ago
      Those are called emoticons, not emoji. "Emoji" came about specifically to distinguish the single-character ones (unicode or proprietary) from what we did before.
sbondaryev 8mo ago
Great idea, thanks for sharing! Tried your prompts with ChatGPT and Claude than iterated on it. The ASCII doesn't render perfectly in the web interface but looks good when copy/pasted into a text editor. Key benefit: I used to iterate on layout by generating HTML+Tailwind directly, which burns tokens fast. This ASCII approach lets you nail the structure first without the token cost. Much better for free tier usage. Appreciate the writeup!
killerstorm 8mo ago
OK but why not just go back to Balsamiq and make it 'executable'? You might believe that TUI is neutral, but it really isn't - there's a bajillion of different ways to make a TUI / CLI.
arglebarnacle 8mo ago
A really interesting article, and I'm likely to give it a shot a work. I'm grateful for it, and yet I found it difficult to get through because of a sense of "LLM style" in the prose. I won't speculate on whether the post is AI-written or whether the author has adopted quirks from LLM outputs into their own way of writing because it doesn't really matter. Something about this "feeling" in the writing causes me discomfort, and I don't even really know why. It's almost like a tightness in my jaw or a slight ache in my molars. Every time I read something like, "Not as an aesthetic choice. Not as nostalgia. *But as a thinking tool*" in an article I had until then taken on faith was produced in the voice of a human being feels like a let down. Maybe it's just the sense that I believed I was connecting with another person, albeit indirectly, and then I feel the loss of that. But that's not entirely convincing, because I genuinely found the points this article was making interesting, and no doubt they came originally from the author's mind. Since this is happening more and more, I'd be interested to hear what others' experiences with encountering LLM-seeming blog posts (especially of inherently interesting underlying content) has been like.
- iamanllm 8mo ago
  "Not as an aesthetic choice. Not as nostalgia. But as a thinking tool" is a perfectly normal sentence, and I think there is an equally bad trend of people assuming things are AI written and forget that AI was trained on human writing. But to your point, agreed there is a disconnect when things are in fact written by AI, but I skimmed the article anyway so to me it didn't matter lol.
  - oasisbob 8mo ago
    Those are sentence fragments, not perfect sentences. They're useful in some contexts, but are inappropriate for more formalized writing. When LLMs reuse the same patterns dozens of times in a single article, the patterns stops being interesting or surprising and just become obnoxious and grating.
    - iamanllm 8mo ago
      it's not formal writing it's a blog post.
bccdee 8mo ago
Trouble with this is, it's pretty much LLM-only. I don't want to type out a request for Clause to draw a box for me and describe where, and I don't want to be pasting box-drawing characters. I want to click & drag. This is just boxes, arrows, and labels, which are all WAY faster to make by hand.

theturtle32 8mo ago
I love it conceptually, but I can't get past the abject failure of the right edges of boxes to be properly aligned. Because of a mishmash of non-fixed-width characters (emoji, etc.), each line has a slightly different length and the right edges of boxes are a jagged mess and I can't see anything else until that's cleaned up.
- rmunn 8mo ago
  Emojis mixed with ASCII-era characters are hard to get right. Some terminal emulators get it right nearly all the time (e.g. Ghostty, which has had a lot of thought and effort put into getting it right) and yet there are still open issues in the Ghostty repo about inconsistent character width. There are just so many corner cases that it's hard. That said, the edge alignment is, I believe, caused by the fact that LLMs are involved in the process. Because the LLMs never "see" the final visual representation that humans see. Their "view" of the world is text-based, and in the text file, those columns line up because they have the same number of UTF-8 codepoints in the row. So the LLMs do not realize that the right edges are misaligned visually. (And since the workflow described is for an LLM to take that text file as input and produce an output in React/Vue/Svelte/whatever, the visual alignment of the text file needs to stay LLM-oriented for it to work properly. I assume, of course, since I haven't tried this myself).
  - kevin_thibedeau 8mo ago
    They are treated like double width characters. All it takes is a Unicode aware layout algorithm that tracks double width codepoints. The tricky part is older single width symbols that were originally not emoji and now have ambiguous width depending on the terminal environment's default presentation mode.
    - rmunn 8mo ago
      That's how it should work, and does in terminals that are doing it right. Browsers, however, are looking at the monospaced font and saying "Okay, Source Code Pro doesn't have the U+2192 codepoint," (the → arrow) "so let me find a font that does." On my Linux+Firefox setup, the browser chose Menlo to render the → in the "The fastest way to go from 0 → 1" banner. Menlo's width isn't quite identical to Source Code Pro, so the ┃ character on the right of the box was every so slightly misaligned. Because Firefox isn't following strict fixed-width layout rules, and is allowing itself to use other fonts with different horizontal widths even inside a <pre> block. (I haven't looked at this article in other browsers but I bet they're the same since everyone's mentioning misalignment.)

drob518 8mo ago
I really like this idea. I’ve seen teams get stuck quibbling about details too early while using Figma. I see how this totally sidesteps that problem, similar to working with analog drawings, but with the advantage that it’s still electronic so you can stuff it into your repo and version it and also feed it into an LLM easily. I’m really curious how the LLM “sees” it. Sure, it’s characters, but it’s not language. Regardless, very cool idea. Can’t wait to give it a try.
ivanjermakov 8mo ago
Wide character width is yet another billion dollar mistake. Impossible to make emojis look right together with monospaced font across devices/programs.
bulletsvshumans 8mo ago
I think this a good technique to be familiar with, although in a lot of situations I've achieved similar value by simply feeding the underlying JSON data objects corresponding to the intended UI state back into the coding agent. It doesn't render quite as nicely, but it is often still human-readable, and more importantly both LLM and procedurally interpretable, meaning you can fold the results back into your agentic (and/or conventional testing) development loop. It's not quite as cool, but I think a bit more practical, especially for earlier stage development.

Welcome to the 1970s, when IBM published design guidelines that went along with the then-new 3270 terminal, including trying to keep response times very prompt (under a second) to prevent minds from wandering. This was supposed to allow non-technical users to use the full power of customers without having to master a command-line teletype style interface. GUIs were supposed to the big huge thing that would let non-technical staff use computers without needing to grasp TUIs.

Somewhat related I suppose, for reasons I am often in a situation where I can use matplotlib and make a plot then save it and then SCP it locally to view it. I got tired of that and started making command line plots so I can see the stuff I want right there, it's not insanely detailed but for my needs it's been fine. This def got me thinking about it lol
roskelld 8mo ago
This type of issue comes up in the video game development world. Perhaps in part due to modern engines being off-the-shelf ready to render high quality assets and assets being so available, either internally or from an asset store. It helped push developers into putting high quality assets into games from the start, skipping the "grey box" steps. I've had it on a number of projects now where high quality assets were pushed into early builds causing execs eyes to light up as they feel like they're seeing a near final product, blind to the issues and under developed systems below. This can start projects off on bad footing because expectations can quickly become skewed and focus can go to the wrong places. At one studio there was a running joke about trees swaying because someone had decorated an outdoor level with simulated trees. During an early test the execs got so distracted by how much they swayed and if it was too much or too little that they completely ignored the gameplay and content that was supposed to be under review. This issue repeated itself a number of times to the point where meetings would begin with someone declaring "We are not here to review the trees, ignore the trees!" I've brought this issue up more recently with the advent of AI, which with things like Sora, the act of creating video clips can be stitched together can look like subjectively exciting movie trailers. This now has people declaring that AI movies are around the corner. To me this looks like the similar level of excitement as seeing the trees sway. An AI trailer looks much closer to a shipping product than it should be because the underlying challenges are far from solved; nothing is said about the script, pacing, character development, story etc...

Argh. I may suffer from some kind of PTSD here, but after reading a few lines I can't help but see the patterns of LLM style of writing everywhere in this article.
- metalliqaz 8mo ago
  same. I just seem to automatically tune out
- alt187 8mo ago
  Holy cows, same. But it's not PTSD. People think you can tell because of ternary rhythm, —, big-words and other shenanigans. These are tactics over strategy, obsessing over the minutiae. But I think what you're feeling (and what I sure fucking am) is a lack of voice. This writing says something, has a point, and you could even say it has a correct way to get to the point, but it lacks any voice, any personality. I may be wrong -I stopped reading midway- but I really don't think so.
jimbo808 8mo ago
Sorry to be pedantic, but there are a bunch of non-ASCII characters (,↑,) in the mockups and the article contains a lot of AI tropes.
facorreia 8mo ago
Good idea to build low-fidelity mockups. SVG in my opinion is a better format for this job than text. For instance, in the screenshots from the article, not a single example is properly aligned. That is distracting and makes these assets hard to share.
CompoundEyes 8mo ago
Recently I was using docling to transform some support site html into markdown and replacing UI images with inline descriptive text. An LLM created all the descriptions. My hope was descriptions like “a two pane..below the hamburger…input field with the value $1.42…” would allow an LLM to understand the UI when given as context in a prompt. Maybe I could just put ASCII renderings inline instead.
jbmsf 8mo ago
I like the idea but I think it's going to be hard to put this particular genie back in the bottle. As an engineering leader, I prefer low fidelity designs early on, but practically no one else in my company wants that. Designers have learned figma and it's the de facto tool for them; doing something else is risky for them. Product leaders want high fidelity. They love the AI tools that let them produce high fidelity prototypes. Some (but not all) engineers prefer it because it means less decision making for them.
- tranqy 8mo ago
  I'm about to deliver a proposal to a prospect with ascii mocks, we'll see how it goes. I am the product leader.
  - tranqy 8mo ago
    and tbf I've used low fidelity to engage stakeholders imagination long before ai was making ascii for me.
stormy 8mo ago
Most ascii/unicode based diagrams spit out by AI have misaligned boxes, similar to the ones generated in the article. I’m not affiliated, but to clean them up you can use something like ascii-guard (https://github.com/fxstein/ascii-guard https://github.com/fxstein/ascii-guard) which is a linter that will clean it up. Beats doing it by hand after multiple attempts telling AI to do it and repeatedly fail.

We built https://github.com/trabian/fluxwing-skills https://github.com/trabian/fluxwing-skills to handle some of this use case. For the most part it's now on the shelf but we use the react-ink toolkit for similar things. It's faster and aligns better.
ralferoo 8mo ago
Unfortunately, the one thing this article needs to get right is broken: the examples. On my screen (Chrome on Windows on 1080p screen), it's in a scrollable box filling the middle half of the width of the screen. Some of the screens are set to display so many rows in the viewport, I have to scroll down several screenfuls to get to the horizontal scrollbar to view the right hand half, and then I can't see all the important stuff at the top right. Secondly, mixing in emojis makes the font non-proportional so most of the screens don't line up properly. This isn't ASCII driven development, it's not even iso8859-1 driven development.
_blk 8mo ago
Made my day, thanks. I use this so much. Even before AI. With AsciiFlow it has the feel of a whiteboard, but you can shift stuff around. I'll draw simple UI prototypes then rearrange and/or document. I can also easily share it with a colleague to comment or modify.

Nice ! Very true that if you, for example, show a group a button with a given color, they will waste the meeting discussing the color and not what the button should do, so ASCII is a nice way to not have to do that.

tptacek 8mo ago

This is a tangential point (this post is not really about TUIs; sort of the opposite) and I think lots of people know it already but I only figured it out last week and so can't resist sharing it: agents are good at driving tmux, and with tmux as a "browser", can verify TUI layouts. So you can draw layouts like this and prompt Claude or Gemini with them, and get back working versions, which to me is space alien technology.

Get a TUI to the point where it renders something, and get Claude to the point where it knows what you want to render (draw it in ASCII like this post proposes, for instance). Then just prompt Claude to "use tmux to interact with and test the TUI rendering", prompt it through anything it gets hung up on (for instance, you might remind Claude that it can create a tmux pane with fixed size, or that tmux has a capture-pane feature to dump the contents of a view). Claude already knows a bunch about tmux. Once it gets anything useful done, ask it to "write a subagent definition for a TUI tester that uses tmux to exercise a TUI and test its rendering, layout, and interaction behavior". Save that subagent definition, and now Claude can do closed-loop visual and interactive testing of its own TUI development.

    Can you explain tmux's contribution here? I'm confused why this process wouldn't work just the same if CC directly executed the program rather than involving tmux. Are you just using tmux to trick the program under test into running its TUI instead of operating in a dumb-stdout mode?
    - tptacek 8mo ago
      It allows Claude to take screenshots and generate keyboard inputs. It's like TUI Playwright.
      - mrstackdump 8mo ago
        Maybe I'm not understanding it (totally possible!) but could Claude just do that by reading standard out and writing to standard in?
        tptacek 8mo ago
        I had a really hard time getting anything like that to work (you can't just read stdout and write stdin, because you're driving a terminal in raw mode), but it took like 3 sentences worth of Claude prompt to get Claude to use tmux to do this reliably.
        mrstackdump 8mo ago
        I would love to see your prompt if you ever post it anywhere.
        _sinelaw_ 8mo ago
        For Claude, it's enough to prompt "use tmux to test", that usually does the work out of the box. If colors are important I also add "use -e option with capture-pane to see colors". It just works. I used it regularly with Claude and my TUI. For other agents other than Claude I need to use a more specific set of instructions ("use send-keys, capture-pane and mouse control via tmux" etc.) Since I have e2e tests, I only use the agent for: guiding it on how to write the e2e test ("use tmux to try the new UI and then write a test") or to evaluate its overall usability (fake user testing, before actual user testing): "use tmux to evaluate the feature X and compile a list of usability issues"
agavra 8mo ago
This is spot on, I understand very little about how terminal rendering works and was able to build github.com/agavra/tuicr (Terminal UI for Code Review) in an evening. The initial TUI design was done via Claude.
frumplestlatz 8mo ago
I’ve actually got an MCP server that makes it really easy for Claude to generate key events, wait for changes / wait for stable output / etc, and then take PNG screenshots of the terminal state (including all colors/styling) — which it “views” directly as part of the MCP tool response. Wish I could open source it; it’s a game changer for TUI development.

I've had a lot of good luck with AI Agents also being able to read and meaningfully interprete .txt and .ansi dumps from RatatuiRuby's TestHelper module and its `assert_snapshots` [0]. For example, it was able to read the ANSI and figure out that a snapshot had changed because an upstream bug properly rendered bold and underline when it hadn't before.

Neat concept and very inspirational. Is ascii/unicode text UI the way to go here or is there other UI formats even more suited for LLMs?

kmoser 8mo ago
LLMs are surprisingly good at extracting data from other data, so at the end of the day there is no right or wrong, it's what works best for you use case.
ehsanu1 8mo ago
It has to be suited for human consumption too though. I wonder if this has any real benefits over just doing very simple html wireframing with highly constrained css, which is readily renderable for human consumption. I guess pure text makes it easier to ignore many stylistic factors as they are harder to represent if not impossible. But I'm sure that LLMs have a lot more training data on html/css, and I'd expect them to easily follow instructions to produce html/css for a mockup/wireframe.

ucarion 8mo ago

It is news to me that manipulating ASCII art is something AI can do well! I remember this being something LLMs were all particularly horrible at. But I just checked and it seems to work at least with Opus 4.5. claude(1) with Opus 4.5 seems to be able to take the examples in that article, and handle things like "collapse the sidebar" or "show me what it looks like with an open modal" or "swap the order of the second and third rows". I remember not long ago you'd get back UI mojibake if you asked for this. Goes to show you really can't rest on your laurels for longer than 3 months with these tools.

mixmastamyk 8mo ago

Like the idea, but this is definitely Unicode and not ASCII. It's hard to believe someone finished a piece of this length but still misunderstood, especially when some examples have emoji in them. Alternately, they chose a misleading name on purpose. Why? Someone mentioned TUI, which sidesteps the issue entirely.

kmoser 8mo ago
You're technically right, but I think that's a minor quibble. They could have indeed limited it to ASCII (7-bit if you really want to be a purist) and everything would still work just as well.
ehsanu1 8mo ago
It kind of makes sense if you relate it to ASCII art, which is very often not ASCII for similar reasons. The naming evokes that concept for me at least. Naming is hard in general, I'm sure they tried to find a name that they thought worked best. I agree that "TUI" is a better fit though. But not TUI-driven-development, more like TUI-driven-design, followed by using the textual design as a spec (i.e. spec-driven development) to drive GUI implementation via coding agents.
batisteo 8mo ago
I totally agree. It's called Plain Text.

calufa 8mo ago

Author here. High-level: - Problem: AI UI generators are high-fidelity by default → teams bikeshed aesthetics before structure is right. - Idea: use ASCII as an intentionally low-fidelity “layout spec” to lock hierarchy/flow first. Why ASCII: - forces abstraction (no colors/fonts/shadows) - very fast to iterate (seconds) - pasteable anywhere (Slack/Notion/GitHub) - editable by anyone Workflow: - describe UI → generate ASCII → iterate on structure/states → feed into v0/Lovable/Bolt/etc → polish visuals last It also facilitates discussion: - everyone argues about structure/decisions, not pixels - feedback is concrete (“move this”, “add a section”), not subjective More advanced setups could integrate user/customer support feedback to automatically propose changes to a spec or PRD, enabling downstream tasks to later produce PRs.

4b11b4 8mo ago
While I agree a text representation is good for working with LLMs... most of the examples are mis-aligned? Even the very first one (ASCII-Driven Development) which is just a list. I guess this is a nitpick that could be disregarded as irrelevant since the basic structure is still communicated.
NetOpWibby 8mo ago
The problem with ASCII-driven development for me is that emoji ruin the alignment. It’d be nice if they could be forced into monospaced. Emoji aren’t ASCII so maybe that’s the problem too.
- manquer 8mo ago
  Unicode emojis aren’t ascii . Long before Unicode points were assigned we were using emojis in text communication in email and sms. you can always be quite expressive with ones like :) :D :-( or even ¯\_(ツ)_/¯ - although not strictly ASCII.
  - Izkata 8mo ago
    Those are called emoticons, not emoji. "Emoji" came about specifically to distinguish the single-character ones (unicode or proprietary) from what we did before.

sbondaryev 8mo ago

Great idea, thanks for sharing! Tried your prompts with ChatGPT and Claude than iterated on it. The ASCII doesn't render perfectly in the web interface but looks good when copy/pasted into a text editor. Key benefit: I used to iterate on layout by generating HTML+Tailwind directly, which burns tokens fast. This ASCII approach lets you nail the structure first without the token cost. Much better for free tier usage. Appreciate the writeup!

killerstorm 8mo ago

OK but why not just go back to Balsamiq and make it 'executable'? You might believe that TUI is neutral, but it really isn't - there's a bajillion of different ways to make a TUI / CLI.

arglebarnacle 8mo ago

A really interesting article, and I'm likely to give it a shot a work. I'm grateful for it, and yet I found it difficult to get through because of a sense of "LLM style" in the prose. I won't speculate on whether the post is AI-written or whether the author has adopted quirks from LLM outputs into their own way of writing because it doesn't really matter. Something about this "feeling" in the writing causes me discomfort, and I don't even really know why. It's almost like a tightness in my jaw or a slight ache in my molars. Every time I read something like, "Not as an aesthetic choice. Not as nostalgia. *But as a thinking tool*" in an article I had until then taken on faith was produced in the voice of a human being feels like a let down. Maybe it's just the sense that I believed I was connecting with another person, albeit indirectly, and then I feel the loss of that. But that's not entirely convincing, because I genuinely found the points this article was making interesting, and no doubt they came originally from the author's mind. Since this is happening more and more, I'd be interested to hear what others' experiences with encountering LLM-seeming blog posts (especially of inherently interesting underlying content) has been like.

iamanllm 8mo ago
"Not as an aesthetic choice. Not as nostalgia. But as a thinking tool" is a perfectly normal sentence, and I think there is an equally bad trend of people assuming things are AI written and forget that AI was trained on human writing. But to your point, agreed there is a disconnect when things are in fact written by AI, but I skimmed the article anyway so to me it didn't matter lol.
- oasisbob 8mo ago
  Those are sentence fragments, not perfect sentences. They're useful in some contexts, but are inappropriate for more formalized writing. When LLMs reuse the same patterns dozens of times in a single article, the patterns stops being interesting or surprising and just become obnoxious and grating.
  - iamanllm 8mo ago
    it's not formal writing it's a blog post.

bccdee 8mo ago

Trouble with this is, it's pretty much LLM-only. I don't want to type out a request for Clause to draw a box for me and describe where, and I don't want to be pasting box-drawing characters. I want to click & drag. This is just boxes, arrows, and labels, which are all WAY faster to make by hand.

theturtle32 8mo ago

I love it conceptually, but I can't get past the abject failure of the right edges of boxes to be properly aligned. Because of a mishmash of non-fixed-width characters (emoji, etc.), each line has a slightly different length and the right edges of boxes are a jagged mess and I can't see anything else until that's cleaned up.

rmunn 8mo ago
Emojis mixed with ASCII-era characters are hard to get right. Some terminal emulators get it right nearly all the time (e.g. Ghostty, which has had a lot of thought and effort put into getting it right) and yet there are still open issues in the Ghostty repo about inconsistent character width. There are just so many corner cases that it's hard. That said, the edge alignment is, I believe, caused by the fact that LLMs are involved in the process. Because the LLMs never "see" the final visual representation that humans see. Their "view" of the world is text-based, and in the text file, those columns line up because they have the same number of UTF-8 codepoints in the row. So the LLMs do not realize that the right edges are misaligned visually. (And since the workflow described is for an LLM to take that text file as input and produce an output in React/Vue/Svelte/whatever, the visual alignment of the text file needs to stay LLM-oriented for it to work properly. I assume, of course, since I haven't tried this myself).
- kevin_thibedeau 8mo ago
  They are treated like double width characters. All it takes is a Unicode aware layout algorithm that tracks double width codepoints. The tricky part is older single width symbols that were originally not emoji and now have ambiguous width depending on the terminal environment's default presentation mode.
  - rmunn 8mo ago
    That's how it should work, and does in terminals that are doing it right. Browsers, however, are looking at the monospaced font and saying "Okay, Source Code Pro doesn't have the U+2192 codepoint," (the → arrow) "so let me find a font that does." On my Linux+Firefox setup, the browser chose Menlo to render the → in the "The fastest way to go from 0 → 1" banner. Menlo's width isn't quite identical to Source Code Pro, so the ┃ character on the right of the box was every so slightly misaligned. Because Firefox isn't following strict fixed-width layout rules, and is allowing itself to use other fonts with different horizontal widths even inside a <pre> block. (I haven't looked at this article in other browsers but I bet they're the same since everyone's mentioning misalignment.)

I really like this idea. I’ve seen teams get stuck quibbling about details too early while using Figma. I see how this totally sidesteps that problem, similar to working with analog drawings, but with the advantage that it’s still electronic so you can stuff it into your repo and version it and also feed it into an LLM easily. I’m really curious how the LLM “sees” it. Sure, it’s characters, but it’s not language. Regardless, very cool idea. Can’t wait to give it a try.

ivanjermakov 8mo ago

Wide character width is yet another billion dollar mistake. Impossible to make emojis look right together with monospaced font across devices/programs.

bulletsvshumans 8mo ago

I think this a good technique to be familiar with, although in a lot of situations I've achieved similar value by simply feeding the underlying JSON data objects corresponding to the intended UI state back into the coding agent. It doesn't render quite as nicely, but it is often still human-readable, and more importantly both LLM and procedurally interpretable, meaning you can fold the results back into your agentic (and/or conventional testing) development loop. It's not quite as cool, but I think a bit more practical, especially for earlier stage development.

Welcome to the 1970s, when IBM published design guidelines that went along with the then-new 3270 terminal, including trying to keep response times very prompt (under a second) to prevent minds from wandering. This was supposed to allow non-technical users to use the full power of customers without having to master a command-line teletype style interface. GUIs were supposed to the big huge thing that would let non-technical staff use computers without needing to grasp TUIs.

roskelld 8mo ago

This type of issue comes up in the video game development world. Perhaps in part due to modern engines being off-the-shelf ready to render high quality assets and assets being so available, either internally or from an asset store. It helped push developers into putting high quality assets into games from the start, skipping the "grey box" steps. I've had it on a number of projects now where high quality assets were pushed into early builds causing execs eyes to light up as they feel like they're seeing a near final product, blind to the issues and under developed systems below. This can start projects off on bad footing because expectations can quickly become skewed and focus can go to the wrong places. At one studio there was a running joke about trees swaying because someone had decorated an outdoor level with simulated trees. During an early test the execs got so distracted by how much they swayed and if it was too much or too little that they completely ignored the gameplay and content that was supposed to be under review. This issue repeated itself a number of times to the point where meetings would begin with someone declaring "We are not here to review the trees, ignore the trees!" I've brought this issue up more recently with the advent of AI, which with things like Sora, the act of creating video clips can be stitched together can look like subjectively exciting movie trailers. This now has people declaring that AI movies are around the corner. To me this looks like the similar level of excitement as seeing the trees sway. An AI trailer looks much closer to a shipping product than it should be because the underlying challenges are far from solved; nothing is said about the script, pacing, character development, story etc...

alt187 8mo ago
Holy cows, same. But it's not PTSD. People think you can tell because of ternary rhythm, —, big-words and other shenanigans. These are tactics over strategy, obsessing over the minutiae. But I think what you're feeling (and what I sure fucking am) is a lack of voice. This writing says something, has a point, and you could even say it has a correct way to get to the point, but it lacks any voice, any personality. I may be wrong -I stopped reading midway- but I really don't think so.

jimbo808 8mo ago

Sorry to be pedantic, but there are a bunch of non-ASCII characters (,↑,) in the mockups and the article contains a lot of AI tropes.

facorreia 8mo ago

Good idea to build low-fidelity mockups. SVG in my opinion is a better format for this job than text. For instance, in the screenshots from the article, not a single example is properly aligned. That is distracting and makes these assets hard to share.

CompoundEyes 8mo ago

Recently I was using docling to transform some support site html into markdown and replacing UI images with inline descriptive text. An LLM created all the descriptions. My hope was descriptions like “a two pane..below the hamburger…input field with the value $1.42…” would allow an LLM to understand the UI when given as context in a prompt. Maybe I could just put ASCII renderings inline instead.

jbmsf 8mo ago

I like the idea but I think it's going to be hard to put this particular genie back in the bottle. As an engineering leader, I prefer low fidelity designs early on, but practically no one else in my company wants that. Designers have learned figma and it's the de facto tool for them; doing something else is risky for them. Product leaders want high fidelity. They love the AI tools that let them produce high fidelity prototypes. Some (but not all) engineers prefer it because it means less decision making for them.

Most ascii/unicode based diagrams spit out by AI have misaligned boxes, similar to the ones generated in the article. I’m not affiliated, but to clean them up you can use something like ascii-guard (https://github.com/fxstein/ascii-guard https://github.com/fxstein/ascii-guard) which is a linter that will clean it up. Beats doing it by hand after multiple attempts telling AI to do it and repeatedly fail.

Unfortunately, the one thing this article needs to get right is broken: the examples. On my screen (Chrome on Windows on 1080p screen), it's in a scrollable box filling the middle half of the width of the screen. Some of the screens are set to display so many rows in the viewport, I have to scroll down several screenfuls to get to the horizontal scrollbar to view the right hand half, and then I can't see all the important stuff at the top right. Secondly, mixing in emojis makes the font non-proportional so most of the screens don't line up properly. This isn't ASCII driven development, it's not even iso8859-1 driven development.
