Masterful is a note-taking system with full-text search, wiki-links, and a native MCP server — so Claude can search, read, and write in your knowledge base directly.
No telemetry · Your data stays yours
Welcome to Masterful — your AI-native knowledge base.
Connect Claude via the /mcp endpoint and ask it anything about your notes.
Use [[wiki-links]] to connect related ideas. Backlinks are tracked automatically.
Run Masterful with a single Docker command on Fly.io, your own server, or a Raspberry Pi. Up in minutes.
Write notes in Markdown with folders, tags, and
[[wiki-links]]. Backlinks are tracked automatically.
Point Claude at your MCP endpoint. It can now search, read, and write your notes — answering with your context.
Built for developers who think in systems — and who want their AI assistant to actually know what they know.
Connect Masterful as an MCP server. Claude can search, read, create, and update your notes directly inside any conversation.
Instant full-text search across all your notes, plus AI semantic search that finds results by meaning — not just keywords. Filter by folder, tag, or content in milliseconds.
Link notes with [[note name]] syntax. Backlinks are tracked automatically so you always see what
connects.
Organize with nested folders and color-coded tags. Browse and filter your knowledge exactly how your brain naturally works.
Your notes are encrypted end-to-end. Zero telemetry. Your knowledge stays private and fully under your control.
Mark any note as private and it stays invisible to the AI. You stay in full control of what Claude can and cannot access in your knowledge base.
Share individual notes or entire collections with others via a simple link. Collaborate and publish your knowledge on your terms.
Get an instant AI-generated summary of any note. Catch up on long documents or revisit old ideas without reading everything from scratch.
Download all your notes as a .zip or grab the raw SQLite file anytime. No lock-in, ever.
Most knowledge tools are disconnected from your AI. Masterful bridges that gap with a built-in MCP server — Claude can search, read, and write your notes directly inside any conversation, without copying and pasting.
What decisions did we make about the API design last month?
Based on your notes, you decided to stick with REST for now. The "GraphQL vs REST" note from two weeks ago outlines three reasons: team familiarity, simpler caching, and fewer client dependencies...
We're opening MasterfulHQ to a small group of early users. Get priority access, shape what we build next, and lock in a founding-member rate.
