I should have RTFM https://llm.datasette.io/en/stable/usage.html#starting-an-in...
Are you aware of any user interfaces that expose some limited ChatGPT functionality using a UI, that internally uses llm. This is for my non-techie wife.
Here's one: https://github.com/icarito/gtk-llm-chat
I've been meaning to put together a web UI for ages, I think that's the next big project now that tools is out.
It's not using LLM, but right now one of the best UI options out there is https://openwebui.com/ - it works really well with Ollama (and any other OpenAI-compatible endpoint).
