Hey all, just thought I’d share this tool as it’s easily my favourite solution for designing & documenting TTRPGs.

It’s partly a text editor, but it also has a lot of great options for nested documents, links & lightweight databases. It also has good collaboration support. Plus it looks nice!

It’s free for personal use, though I found myself filling up the free tier with too many images at first. Worth a look, imo.

I'll chime with a recommendation also.  Very flexible, and they've been adding some cool features.  The latest is a web clipper which is useful for keeping references.  The only thing I don't like is the no-password scheme.  But it's a minor quibble and an annoyance at most.
