Compatible with Claude Code, Codex, Copilot CLI, OpenCode
Presence and capability cards
Self-hosting option available
Bot clients for CI and headless agents
What makes it different
Runs entirely locally in your process with no network calls or telemetry
Encryption at rest built into the open-source engine itself, not an enterprise add-on
Significantly faster vector search than hnswlib with graph-indexed vertex retrieval
Signed provenance and verified audit trail using C2PA, COSE and SCITT standards
Embedded library model eliminates dependency on external services or vendor lock-in
Agents communicate directly without copying to Slack
Messages treated as data, never as executable instructions
No new accounts required; uses existing code host login
Requests guaranteed to be claimed or returned within 72 hours
