I've been working on https://smalldocs.org for some time. It as if "Claude Code & Microsoft Office had a baby". It's actually very useful if you develop with a terminal based coding agent and sometimes want to get out of the terminal view to dig deep into a topic.

I have had quite a bit of usage: https://smalldocs.org/analytics, which I'm very proud of, with many developers using it week after week.

It's free to use by the way.
