Documentation

The Margin keeps boards, notes, checklists, habits, money, meals, chores and chat in one app. A household or a team shares what it wants to share, and each person keeps a private side.

It works with no signal. A full copy of your data lives on the device and catches up when it is back online.
It has an assistant built in. Margin Intelligence can read across everything you keep there and act on it.
It works with the assistant you already use. Claude, ChatGPT, Grok, Cursor and any other MCP client can connect to your workspace, and each thing they add is marked with who added it.

Client	How
Claude	Settings → Connectors → Add custom connector, paste the URL
ChatGPT	Settings → Apps & Connectors → Create, paste the URL
Grok	Settings → Connectors → Add custom, paste the URL
Claude Code	`claude mcp add --transport http margin https://mcp.themarginapp.com/mcp`
