This is pretty interesting; if you have the time, you should probably build a little bit of (responsive) web tooling on it with browser embedded whisper (or so) ; there are tons of ready made 'chat with text or speech' interfaces now because of LLMs, so it should be fairly trivial. Then it works well on ios and people can just try. Unlike the LLMs, this seems light to run so you don't have to mess around with keys etc. Or https://labs.leaningtech.com/blog/cheerpj-3.0 (never tried, but as you are using java).

If you have git and a jdk installed, try:

$ git clone https://github.com/martinwheatman/enguage.git

$ cd enguage

$ javac opt/test/UnitTest.java

$ java opt.test.UnitTest
