One brain for you and your agents.
A quiet, local-first Markdown vault. A rich desktop app for the person thinking, and a CLI and MCP server for the agents helping — one folder of plain Markdown files you own.
Free and open source · macOS, Windows and Linux01 · Your files
Your notes are files. The folder is yours.
Plain Markdown. Obsidian-compatible links. A folder you can open in any editor — today and years from now.

Bring in agents
Give agents the same local access through the CLI or MCP server.
A quiet place to think
Three columns, a rich editor, and the whole vault as a living map. Everything renders where you write — tables, math, diagrams, media — and one key returns you to the plain Markdown underneath.
Live editor
CodeMirror 6 with tables, KaTeX math, Mermaid diagrams and note embeds rendered in place. Click a block to edit its Markdown.
Reading view
⌘E turns the note into a calm, typeset page — for review, or for a long read.
The graph
The vault as a deterministic force-directed map. Filter by tag, click a node to open the note.
Command palette
⌘K runs anything; ⌘P jumps to any note. Keyboard-first, without leaving the keyboard.
Backlinks and links
The index knows every connection, and every unresolved one.
Your agents work the same brain
The CLI and the MCP server are clients of the same engine the app uses. An agent sees exactly what you see — the same folder, the same index, the same rules about what may be written.

monet skills add installs skills generated from the command declarations themselves, so agent guidance always matches the tool. Nothing to author, nothing to keep in sync.
Confined writes
Agents and the app write only inside the vault, with symlink checks and revision conflict detection.
One vault, from three angles
Write, explore connections, or read without distractions. Every view works from the same files.
