Local-first

Every note is a real file on your machine. We don’t host your archive. That isn’t nostalgia — it’s the only way notes stay yours when tools change, and the only way agents can attach without a second vault.

Where notes live

By default Markdown Locker saves to:

~/Documents/Markdown Locker

That folder is ordinary. Finder can open it. Spotlight can index it. VS Code, Obsidian, or any text editor can read the same .md files. There is no proprietary database you have to export from.

Why this matters for AI

When Think or Workspace runs, it uses context from files already on disk. Your API key talks to the model you choose; the locker stays local. You are not uploading a permanent copy of your life into our servers — because we don’t run that kind of store.

The same folder is what Grok Build or Cursor can attach via MCP. Attach. Don’t upload. See Connect Grok.

Local-first also means offline capture still works. Connectivity is for models and page fetch when you ask for it — not for permission to save a thought.

Privacy, simply

• Notes are files under your user account
• Pro and license state stay on the device
• API keys you paste stay on the device
• We don’t need an account just to write a note

Durability

Formats come and go. Plain markdown has survived decades of app churn. Building on it is a bet that your notes should still open in ten years — with or without this app. Versioned Save keeps an on-disk trail when you overwrite a note (read the release note).
