It feels like notetaking/wiki software have gotten a resurgence in the last few years. Not that it was ever not a thing, but like a new generation of people realized wanted to build new tools for it. Personally, I think the variety of tools is very interesting, and while I like Obsidian and plain markdown file, I do love to see different options in the space with hosted options and different capabilities. Notion feel…
(a) git versioned
(b) CRDTs
(c) WYSIWYG but Markdown (esp GFM)
(d) front matter + markdown able to be SSGd
(e) comfortable UI for not-devs
(f) native (Swift) MacOS app, else Tauri/Electron self-hosted client+svc
(g) if online, OIDC / SAML SSO
Appears this can be cobbled leveraging Obsidian plugins, but unstable due to git vs. CRDT issues. And there are a few "CMS" for SSG stacks that almost but not quite meet this.
