Claude on your Mac. Cursor on your laptop. Windsurf at the office. One shared memory — goals, decisions, the rationale behind them — follows you across every tool and every machine. Switch IDEs and your AI still knows your project, because the memory lives in files you own — not locked inside one vendor. End-to-end encrypted. Keys stay with you.
Via MCP (Model Context Protocol), memoir gives every AI tool access to a shared memory layer. Your AI reads and writes memory automatically as part of the conversation — no manual note-taking, no re-explaining.
Tell Claude your API conventions once. Tomorrow, in Cursor on a different laptop, it already knows — and it knows why you decided that.

Lives inside one tool. Switch editors — or just open a different one — and the context is gone. Your memory is their retention feature.
Great until you pick up a second machine. One laptop, one database, no sync, no team. Your context is trapped on the device it was typed on.
Every tool, every machine, one memory. Stored in files you own, encrypted with keys only you hold — and shareable with your team. Leave any vendor; keep your memory.
The decisions, conventions, and rationale your team builds up — available in Claude, Cursor, and Gemini, on every machine, to every seat.
A new dev's AI inherits the whole project's context immediately — no "ask the senior dev," no ramp-up tax.
End-to-end encrypted, with per-project isolation for agencies juggling clients. Your team's keys, not ours.
