WARM Cloud sync, backup and verification without server access to keys or documents
What makes it different
Maintains indexed knowledge with automatic scheduled refreshes
Provides source references for verifiable answers
Supports both public and private knowledge sources
Handles infrastructure for data pipelines
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
