MCP support built-in
Your notes, accessible to any AI agent.
MCP (Model Context Protocol) is the open standard that lets AI assistants talk to apps. NoteOperator ships with a fully compatible MCP server — no plugins, no third-party bridges.
Create a scoped key, paste one command, and your AI can browse folders, read documents, draft new notes, and update existing ones — right inside a conversation.
- Works with Claude Code & Claude Desktop
- Works with Cursor, Windsurf, and any MCP client
- Scoped permissions — view, edit, delete independently
- Revoke keys at any time

Who uses NoteOperator?
If Notion feels like too much and a plain text file isn't enough, NoteOperator is the middle ground.
Solo builders
Keep a dev journal, project notes, and documentation in one place. Export any doc as PDF when you need to share it.
AI power users
Let Claude draft your notes, summarise research, or update your changelog — directly inside your workspace.
Small teams
Share a public doc link instead of setting up a wiki. Readers don't need an account — just the link.
Researchers & writers
Focus on writing with a distraction-free editor. Autosave keeps you from losing work. Export to PDF when done.
Frequently asked questions
Do I need to know Markdown?
No. There's a formatting toolbar for bold, headings, lists, and more. Markdown is just the file format — you never have to type a symbol if you don't want to.
What is MCP?
MCP (Model Context Protocol) is an open standard that lets AI assistants read and write data from apps. Think of it as giving your AI a secure key to your notes — it can read, create, and edit documents on your behalf, inside any conversation.
Which AI agents work with NoteOperator?
Any MCP-compatible client: Claude Code, Claude Desktop, Cursor, Windsurf, and custom agents built with the MCP SDK. If it speaks MCP over HTTP, it connects.
Is it really free?
Yes, completely free right now with no limits. No credit card, no trial period.
Is my data private?
Documents are private by default — only you can see them. You choose which ones to make public. MCP keys are scoped so agents only get the permissions you explicitly grant.
How is this different from Notion or Google Docs?
It's deliberately simpler. No databases, kanban boards, or wikis — just documents and folders. The key difference is first-class MCP support: AI agents can read and write your notes directly, not just chat about them.
Do I need to install anything?
Nothing to install. NoteOperator runs in the browser. Sign in with Google or GitHub and you're writing in seconds.
