Why not something else?

A code editor first. Here the workflow is built around notes: Live preview with images, PDF export, local drafts, link rewriting on move.

A desktop and mobile app; syncing a vault through Git needs a plugin or your own setup. Here: open the repo in any browser, nothing to install.

Centred on single documents. Here you work with a whole repository: file tree, multi-file commits, conflict recovery, link rewriting.

Notes live inside their service. Here notes are plain Markdown or HTML files in your repo, with full git history.

Questions

Is my code safe?

Server never stores your token. Token lives only in this tab's sessionStorage, destroyed on close.

Does it work with private repositories?

Yes. Same OAuth grants access to any repo you permit. Previews work on private repos too.

What if I lose connection?

Edits land in IndexedDB within 400 ms. Reconnect and pick keep-or-discard — nothing merges automatically.

Can I self-host it?

Yes — Cloudflare Pages free tier. Callback is Pages Functions. See README-CLOUDFLARE.md.

What about my OneNote / Obsidian collection?

Export to markdown, push to a GitHub repo, open it here — plain files with full git history.
