What is Itsuki?
Itsuki is a memory layer that unifies context across 26+ AI tools and coding assistants by extracting and structuring memories from conversations, documents, and events through a single API key. Users type context once in any tool (Claude, ChatGPT, Cursor, LangChain, etc.) and Itsuki recalls it everywhere, keeping memories structured as facts, entities, relationships, and events—fully citable and version-controlled.

Itsuki pros
- Integrates with 26+ tools via one API key (Claude, ChatGPT, Claude Code, Cursor, LangChain, CrewAI, n8n, Dify, agent frameworks, and more)
- Structures memories intelligently (facts, events, entities, relationships) rather than storing raw conversation—recalls relevant context without flooding prompts

- Full audit trail and version control—every memory is dated and linked to its source; deletions actually delete with no residue
Itsuki cons

- Requires setup and integration work; not a plug-and-play solution for every workflow
- Limited visibility into privacy guarantees and data storage practices on the landing page
