Gives AI chatbots and agents a real memory — so they remember what you told them last week — instead of forgetting everything the moment a conversation ends, the way most AI apps do by default.
Best alternatives to Itsuki in 2026
Every AI chat assistant you use — Claude, ChatGPT, Cursor, whatever's next — forgets everything the moment the conversation ends, and none of them share what they learned about you with each other. Itsuki is an attempt to fix that by acting as an external memory that any of those tools can read from and write to: it watches conversations, documents, and events, pulls out durable facts ("this person prefers TypeScript," "this project uses Postgres"), and makes them available the next time you talk to any connected tool. Technically, it's infrastructure for developers rather than a consumer app: you integrate it via REST API, official SDKs, or the Model Context Protocol (MCP), and it exposes structured memory objects — facts, events, entities, relationships — each linked back to its source with an audit trail, and genuinely deletable (not just hidden) if you need to remove something. It claims connections to 26+ AI tools and frameworks including LangChain and CrewAI, runs on Cloudflare's edge stack (Workers, D1, Durable Objects), and is open source under Apache 2.0. It's in early access with a small usage cap (~100 saves/day) and a genuinely small GitHub following so far, which is typical for infrastructure this early but worth knowing before building critical paths on it.
