Does HN have any recommendations for offline voice assistants? I just want a voice assistant which can do basic things for me locally without connecting to the internet for simple tasks such as adding things to my calendar or a note, playing a song, opening an app and alike. I'm using Android, but I'm sure others using iOS would also appreciate some suggestions.
