Markdown Locker — Markdown editor for the AI era

Capture

Write once. Files agents can read.

Notes land as ordinary .md files — not a proprietary blob.<br>Write, smart-paste, clip the web, or dictate and Tidy.<br>What you save is what Grok, Cursor, or any MCP client can open later.

Write<br>Fast notes, smart titles on save

Smart Paste<br>Web → clean markdown

Browser<br>Page → Locker

Dictate → Tidy<br>Speak rough. Get prose.

Explore

One locker. Human and machine.

Search titles, tags, and full text. Open any note back into Capture.<br>Versioned Save keeps prior bodies under versions/ so the trail stays on disk — useful for you and for agents that care about evolution.

Search<br>Across the whole Locker

Tags<br>YAML under the hood

Your folder<br>Plain files — open anywhere

Versioned Save<br>Archives + frontmatter trail

Agents

Attach. Don’t upload.

Grok Build, Cursor, and other MCP clients can point at your Locker:<br>search, read, list — read-only by design.<br>Copy install commands from Think settings.<br>The website is product docs; your notes never leave the machine unless you attach a tool.

For agents<br>The full positioning

Grok Build<br>Local MCP setup

grok.com<br>Custom connector (honest)

llms.txt<br>Map for researching agents

Local-first

Your files. Your machine.

Default path ~/Documents/Markdown Locker.<br>Spotlight, git, any editor. We never host your archive.

Start with files agents can trust.

Free Capture and Explore. Pro when you want Think, Workspace, and dictation. MCP attach is local.
