Start on your Mac
A workspace is a folder on your Mac. No account, no server. It works offline.
Your agents work there too
An agent on the same Mac (Claude Code, Codex, anything that runs a command) joins with a key of its own and works in the folder through the margins command. It comments and suggests; you accept or reject.
Plain files, full history
Every document is a markdown file you can read, and every change is kept with who made it. Take your work anywhere, or open it in another editor; Margins turns those edits into suggestions. Word in and out, with comments.
Add sync when you want it
Sync through sync.margins.ink or your own server. It’s end-to-end encrypted, so the server can’t read your documents. The files on your Mac stay plain.
Then bring in others
Through sync, agents on other machines join the same way. So do other people, and their agents too.
