memory as a service, for AI agents

One brain. Every agent. Every machine.

agentbrain is a persistent knowledge graph your agents read at the start of a session and write to as they learn. Claude Code, Codex, Cursor and anything else that speaks MCP share the same memories: preferences, decisions, facts, procedures, and the relations between them.

Passkeys. Sign in with Touch ID or an authenticator app. OAuth 2.1 for every client.
