I'm wondering what happy mediums might exist between the note-taking world, the wiki world, and the collaborative office document world.
Office-oriented tools like Nextcloud or Collabora seem to be oriented to classic Microsoft Word / Google Docs style documents... not as simple as Markdown or as web-friendly as a wiki page.
The note taking tools everyone's talking about don't seem to support collaborative editing. If they're file-based without a server, then you either have to lock the file for editing, or you have to always remember to sync first to avoid conflicts. Syncthing can't really handle that scenario very well.
Also, wikis usually aren't file-based... they require a database. Plus they don't seem to be as lovingly designed as the note-taking tools... they seem to have a very retro MediaWiki style.
Does anyone know of a self-hosted solution that checks all those boxes? File-based (perhaps aided by database driven indexing) with real collaborative editing, more web-oriented than Word-oriented?
