One key · 26 tools — assistants, coding agents, workflows
One store sits under all twenty-six. Type the fact once, in whichever tool happens to be open, and the next tool to ask gets it back — no export, no re-paste, no second store to keep in sync.

An example memory
“We’re on Postgres. No ORM — raw SQL only.”
you typed this once, in whichever tool was open.
Everyone else replays the transcript and hopes the model finds the point. Itsuki keeps the point, the exact words it came from, and the shape of what it connects to.
“hey are we still on for the review” “let me check the calendar one sec” “ok so september is completely packed” “we're moving the pricing review to october” “who's calling it?” “the growth lead owns it now” “cool, i'll tell the team” “thanks!”
- 10 more turns of the same, replayed on every request.
Discarded on purpose: greetings, scheduling chatter, and questions with no durable answer. Your rules decide what never becomes memory.
“Who moved the pricing review, and when?”
A worked example. Every memory stays linked to the words it came from — your agent receives four typed objects and a source it can cite, not eighteen turns to re-read and guess at.
Four moves. One living memory.
Conversations, documents, and events enter through one consistent memory API.
“The pricing review moved from September to October.”

Move fast without turning memory into a black box.
The Itsuki principleRead the extraction engine. Read the admission rules that decide what becomes memory. Read the delete path. The engine, the SDKs and the schema history are published under Apache 2.0 — memory infrastructure you cannot inspect is just another black box. Publication runs behind deployment: the hosted service is built from a development line, so the newest modules and migrations reach the repository later.
