Itsuki

Sign up free, go to the Connect tab, and create a private MCP link. On a computer, open claude.ai → Settings → Connectors → Add custom connector, name it "itsuki", paste your private link, and add it. Then in a chat, tap the + (bottom-left) → Connectors → switch on Itsuki. It works on the free plan.

Yes, but with requirements: go to ChatGPT Settings → Connectors (called Plugins in some builds) → Advanced → turn on Developer mode, then create a connector named "itsuki" with your private MCP URL. It needs a paid ChatGPT plan (Plus/Pro/Business); free accounts can't add custom connectors. Mobile can use it after setup, with some limits.

Yes. The dashboard shows a living graph with timelines and organized pages. You can open, search, drag, and edit memory objects, and every save has a receipt showing what was saved, updated, or refused, with source and timestamp.

Itsuki states it does not sell user data, does not use memory for unrelated purposes, and does not train on your memory. You can export everything as JSON or delete it all anytime with one click. Connected tools access memory only through private links or tokens you create, and you can revoke them from Connect.

Set up on a computer browser — neither Claude nor ChatGPT lets you add connectors from their mobile apps. After setup, it syncs to your phone automatically. ChatGPT mobile can use it after setup, but with some limits.

Instead of storing raw chat logs, Itsuki extracts durable facts and writes them as entities, facts, events, relationships, pages, and receipts. The LLM proposes, the backend verifies, and memory can be updated, superseded, or invalidated — not just appended.
