Universal Memory LayerTell it once. Every AI remembers.
Itsuki is one private memory graph shared by Claude, your agents, and your apps — you can see it, edit it, and own it.
Free early access · Open source · You own your memory · Works with API, SDK, dashboard, and MCP-linked clients.
Your memory, as a living graph — real product footage.
How it works
Four steps. Simple enough to explain to anyone.
1
You talk
Tell your AI: "save this to itsuki — I finished Unit 3." Or let your app send it automatically.
2
Itsuki organizes it
AI extracts the durable facts. The backend verifies them and writes real structure — never a raw chat dump.
3
You can see it
Open the dashboard: a living graph, timelines, organized pages — and a receipt for every single save.
4
Every tool remembers
Claude, Cursor, your own agent — all connect to the same private memory. Save once, recall everywhere.
Connect in 2 minutes
Pick your tool. Paste one link. Done.
Sign up, create your private memory link in the Connect tab, then paste it into any MCP-capable client — or call the API from your own app.
Set up on a computer, not your phone. Neither Claude nor ChatGPT lets you add a connector from their mobile apps — do it once in a computer browser and it syncs to your phone automatically.
itsuki · connect
1Sign up free → open Connect → Create MCP link
2On a computer, open claude.ai → Settings → Connectors → Add custom connector (that link opens it directly)
3Name it itsuki, paste your private link, click Add:
4In a chat, tap the + (bottom-left) → Connectors → switch on itsuki
Custom connectors need a paid Claude plan. Once it is set up it syncs to mobile automatically. Then say "save this to itsuki" or "what do you know about me?"
1On a computer: ChatGPT → Settings → Connectors (called Plugins in some builds) → Advanced → turn on Developer mode. Nothing MCP-related appears until this is on.
2Back in Connectors → Create. Name: itsuki. Description: Personal memory — save and recall facts about me across chats. URL:
3In a new chat, enable Developer mode / Add sources and pick itsuki — a saved connector stays off until you switch it on in the chat
Needs a paid ChatGPT plan (Plus/Pro/Business) — Free can't add custom connectors. Mobile can use it after setup, with some limits.
1Create your MCP link in the Connect tab, then run:
Claude Code gets three tools: save_memory, save_conversation, recall_memory.
1Add Itsuki to your MCP config (.cursor/mcp.json):
Works the same in any MCP-capable editor or agent host.
1One call: recall relevant memory and auto-save the turn:
Plus /v1/save, /v1/recall, /v1/graph, /v1/rules, /v1/export — same private graph.
Honest MCP note
When Itsuki is connected through an MCP-capable AI client, Itsuki provides memory tools. The client or host model decides when to call them. If you need guaranteed per-turn capture or recall, use the Itsuki API or SDK inside your app or agent runtime.
Why a graph
Structured memory, not transcript replay.
Itsuki turns useful context from chats, events, documents, tools, and workflows into structured memory objects — entities, facts, events, relationships, pages, and receipts.
Chat history is not memory.
Messages are source material. Itsuki keeps the durable meaning that should survive beyond a single exchange.
Memory is structured meaning.
Itsuki stores verified entities, facts, events, relationships, rollups, and receipts so systems can reason over them later.
Backend is the authority, not the LLM.
The LLM proposes; Itsuki verifies; Itsuki writes. Recall and extraction stay separate.
What makes it different
A graph that can update, not just append.
New evidence can create, update, promote, invalidate, or supersede memory. Itsuki is not an append-only chat log.
A memory you can see
Your facts live in a visual graph with clusters you can open, search, drag, and edit — not a hidden blob.
Latest truth wins
Say "actually, that changed" — the old fact is superseded and kept as visible history on a timeline, not deleted, not duplicated.
Receipts for every save
Each write returns proof: what was saved, updated, or refused — with source and timestamp. No silent writes, ever.
Your rules
Decide what gets collected and what must never be saved — plain-language rules the backend actually enforces.
One graph, many inputs
Chat is one input. Not the whole product.
Itsuki can ingest useful context from tools, apps, agents, docs, events, workflows, and custom schemas.

Private by default
Your memory belongs to you. Provably.
No ads. No trackers. No selling data. No training on your memory. Export everything as JSON or delete it all — any time, one click.
Privacy Policy
Itsuki does not sell user data or use user memory for unrelated purposes. User memory belongs to the account that created it. Connected tools are third-party services and access Itsuki only through private links or tokens you create.
Terms of Service
Itsuki is an early product and may change. Use it responsibly. You are responsible for tokens and private links, and you can revoke them from Connect. Avoid sensitive or regulated data unless Itsuki is appropriate for that use.
Build memory once. Use it everywhere work continues.
Free early access — founding users keep the Pro tier free when paid plans launch.
