Love this, and love that you're using Elixir LiveView as well as Elixir with the Slack bot and lastly that you're based in Tokyo.
Followed you on Github, I'm looking at moving (back) to Japan in two years, likely to start a bootstrapped startup business and always good to have dev friends!
Then things like:
“Fix My Japanese” - uses LLM to correct Japanese grammar (built with Elixir LiveView): https://fixmyjapanese.com
It has different “Senseis” that are effectively different LLMs, each with slightly different style. One is Claude, one is ChatGPT.
Or a slack bot that summarizes long threads:
