In development - Apache 2.0

Your agent
forgets everything.

Context0 is an open-source memory engine for AI agents. It remembers what matters across sessions, understands how those memories relate, and runs entirely on your own infrastructure.

One email when it ships. No newsletter, no sharing your address.

What it does

Memory that knows what changed.

Most memory for agents is a pile of text chunks retrieved by similarity. That finds things that sound alike, but it cannot tell you which fact is still true. Context0 keeps the relationships between memories, so it can.

Remember

Feed it a conversation. It pulls out the facts, preferences, and events worth keeping, without being told what to look for.

Connect

Memories are stored as a graph, so a new fact can supersede an old one instead of quietly sitting next to it.

Recall

Ask a question, get the few memories that actually answer it, along with the relationships that explain why.

How it is built

Yours to run.

Open source: Apache 2.0, every dependency OSI-approved. No open-core bait, no license rug pull.
Self-hosted: Runs on your own infrastructure. Your conversations never leave it.
Framework-agnostic: Not tied to one model or one agent framework. Any agent can share the same memory.

Be there when it ships.

Context0 is being built in the open. Join the waitlist for one email when the first release lands, or follow along on GitHub.
