One memory across every AI tool and every machine — Claude on your Mac, Cursor at the office, same context. It lives in files you own — synced with end-to-end encryption, locked inside no vendor.
memoir saves what you and your AI learn together — decisions, lessons, context — and hands it to every future session. Any tool. Any machine.
A reminder set once kept surfacing at every session start — across days, sessions, and a model switch — until done.
A bad deploy was written to memory once; every later deploy followed the rule unprompted.
Months later, "why did we do it this way?" answers in seconds — with the rejected alternative.
memoir whyVia 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.

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.
| Built for | Memory lives | Open format | |
|---|---|---|---|
| Mem0 | Developers building agent apps (memory API) | In the app you build | No — proprietary API |
| IDE memory (Cursor, etc.) | One tool, one vendor | Inside that IDE | No |
| claude-mem | Claude auto-capture | Inside Claude's world | No |
| memoir | You — across every AI tool and machine | In files you own, E2E encrypted | Yes — published spec |
Auto-detects your GitHub, creates a private repo, backs up everything.
Add memoir as an MCP server to any tool that supports it.
Start a conversation. memoir works in the background.
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.
One command. Tomorrow's session picks up where today's left off.
