Markdown × Agents, built for writing
Writing, back to its purest form
Koinote is a Typora-style online Markdown editor. Render as you type, upload images inline, and let your agents work safely with your documents.
- What you see is what you get — Typora-style single-pane editing. Render as you type — no split source/preview.
- Markdown fidelity — CommonMark at the core. Import and export round-trip cleanly, migrate anytime.
- Deep image hosting — Drag & paste to upload. Bring your own image host; keep clean links in the body.
- Agent collaboration — Connect Codex, Claude Code, OpenCode, and other agents through MCP with scoped document access.
- Easy export & share — Markdown / HTML export out of the box. Share via read-only links in one click.
- Auto save — Saved as you type, with revision conflicts preventing browser and agent edits from silently overwriting each other.
Bring agents into your writing workflow
No browser extension required. Create a revocable, expiring personal token and let standard MCP clients such as Codex, Claude Code, and OpenCode search, read, and edit Koinote documents within the scope you grant.
- Scope access — Issue read-only or read-write tokens, then reveal, copy, or revoke them anytime.
- Write safely — Every mutation checks the document revision, so conflicts never overwrite silently.
- Keep recovery points — Members can tune full history, with a latest safety snapshot even when it is off.
