Your knowledge base,
natively wired to Claude

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.

Getting started with Masterful

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.

Three steps to a smarter second brain

Step 1

Deploy

Run Masterful with a single Docker command on Fly.io, your own server, or a Raspberry Pi. Up in minutes.

Step 2

Capture

Write notes in Markdown with folders, tags, and [[wiki-links]]. Backlinks are tracked automatically.

Step 3

Ask Claude

Point Claude at your MCP endpoint. It can now search, read, and write your notes — answering with your context.

Everything your knowledge needs

Built for developers who think in systems — and who want their AI assistant to actually know what they know.

Native Claude integration

Connect Masterful as an MCP server. Claude can search, read, create, and update your notes directly inside any conversation.

Advanced searching

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.

Wiki-links & backlinks

Link notes with [[note name]] syntax. Backlinks are tracked automatically so you always see what connects.

Folders & tags

Organize with nested folders and color-coded tags. Browse and filter your knowledge exactly how your brain naturally works.

End-to-end encrypted

Your notes are encrypted end-to-end. Zero telemetry. Your knowledge stays private and fully under your control.

Private notes

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 notes & collections

Share individual notes or entire collections with others via a simple link. Collaborate and publish your knowledge on your terms.

AI note summaries

Get an instant AI-generated summary of any note. Catch up on long documents or revisit old ideas without reading everything from scratch.

Export & backup

Download all your notes as a .zip or grab the raw SQLite file anytime. No lock-in, ever.

Claude MCP integration

Claude knows what you know

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.

  • Search your entire knowledge base in seconds
  • Read any note by name or topic
  • Create and update notes from inside Claude
  • Answer questions with your actual context, not guesses

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...
