End-to-end encryption
Notes are encrypted client-side before leaving your device. Keys are derived from an emoji-based passphrase — memorable, shareable, and never transmitted. The server never sees plaintext.
- AlgorithmAES-256-GCM with unique IV per operation
- KeysEmoji passphrase, stays in the URL fragment (never sent to server)
- Zero-knowledgeOnly key holders can decrypt
- AI agentsAgents on your computer read and write them through the open-source E2E bridge
- PlanPro feature; free notes are unencrypted

Questions
No. Anyone with the link can open the note in a browser and edit it with you. Each person shows up with their own cursor and a random name like Swift Fox.
Yes. Connect Claude, ChatGPT, Cursor or VS Code to static.md over MCP. The agent's edits merge into the open note, and if it tries to rewrite lines someone changed since it read them, the edit is refused instead of overwriting their text.
Yes, if it runs on your computer: Claude Code, Claude Desktop, Cursor, VS Code or Codex. The open-source E2E bridge holds the key there and decrypts for your agent, so static.md only ever stores and sends ciphertext. Chat apps in the browser, like claude.ai and ChatGPT, can't open encrypted notes. Encryption is part of Pro.
With Pro you can share a read-only link, or limit a note to people you name by email. On the free plan, anyone with the link can edit.
Yes. The free plan includes real-time editing, sharing by link and Markdown download, and lets you create 10 notes an hour. Pro removes that limit and adds end-to-end encryption, read-only links, access control and search inside your notes.
Download any note as Markdown, free and unlimited. PDF and HTML exports are 2 a day on the free plan (watermarked) and unlimited on Pro.
static.md is markdown first and built for AI agents as well as people: your agents can search, read and write your notes over MCP, with only the access you approve. There's no workspace to set up; a note is a link.
Write together.
Start a note, then send the link to whoever you're writing with
