MCP server for your assistant
Claude, Codex and other assistants can search and read your notes and todos through a local MCP server, read-only unless you let it write.

Everything Jotzen does.
Each feature links to its page in the documentation. Jotzen is in testing: this is what the desktop app does today.
AI
Built to work with the AI assistant you choose, with you in control.
Read, and write when allowed
Search, read, list todos, backlinks and recent changes; with writing on, create notes, add text and update todos.
Read more →Folders you choose
Limit what an assistant sees; notes others shared with you stay out unless you allow them.
Read more →AI-written labels
Everything your assistant writes is labelled until you review it, and nothing is ever deleted.
Read more →Access log
Every request is logged on your computer, never synced.
Read more →Agents in your files
AI agents work in plain Markdown, guided by AGENTS.md; their edits appear at once and never silently overwrite yours.
Read more →No AI of its own
Jotzen hosts no AI and sends nothing to one; your assistant and provider are your choice.
Read more →Notes and the editor
Ordinary Markdown files, written in an editor that shows them as they will look.
Live preview, source and reading
Markdown marks hide on lines you aren’t editing; switch to plain source or a finished reading view.
Read more →Tables, math and diagrams
Edit tables as a grid; math and Mermaid diagrams are drawn on your computer.
Read more →Images and attachments
Paste or drop images; they are saved next to your notes.
Read more →Obsidian conventions
