}Everything your agents need to remember
Built specifically for LLM agent workflows. No generic note-taking tools.
Persistent thought capture
Store thoughts, ideas, and reasoning steps with rich metadata. Query them back instantly with semantic search.
Knowledge graphs
Build and traverse entity graphs automatically as your agents think. Surface hidden connections.
Full run tracing
Every MCP session is logged from start to finish. Inspect the exact sequence of thoughts that led to any conclusion.
API key management
Issue, rotate, and revoke keys per workspace. Fine-grained control without complexity.
Multi-project workspaces
Organize memory across projects. Each project gets its own isolated context, all in one workspace.
Usage & billing transparency
See exactly what you've used, when, and how much it costs. No surprise invoices.
