Beets can do this too! The -C option to avoid copying files and the -W option to prevent writing tags (or set it in the config file) It will still attempt to match and store the results in its DB for later writing to files, or moving, or querying. For the data to be most useful, you will need a client that connect to Beets to get the data though, Im not sure how prevelant those are. You can use the web-ui plugin though.
