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
  • Output sounds like you, not generic AI, because every tool reads the same profiles and style guides
  • Stop re-uploading docs and rewriting instructions for each new tool
  • Individual voice, shared standards on teams
  • Built-in changelogs instead of Git for managing skills
  • Works with any MCP-compatible AI client without vendor lock-in
