| Pricing | Open source under Apache-2.0 license. WARM Cloud is in development with usage-based pricing for sync, backup and verification; details to be published at launch.
| Spark: Free (5,000 new memories/month, 100 searches/day). Builder: $19/mo (50,000 new memories/month, 1,000 searches/day). Studio: $79/mo (250,000 new memories/month, 5,000 searches/day). Scale: $249/mo (1,500,000 new memories/month, 20,000 searches/day). Enterprise: custom pricing with unlimited te

| Key features | - Hybrid search combining BM25 lexical and vector scoring
- Vertex graph vector index with 2.29-2.75x throughput vs hnswlib
- Vector-symbolic fact memory with holographic reduced representations
- AES-256-GCM encryption at rest with Argon2id key derivation
- Signed audit log with Ed25519 and W3C DID identity
- Secure purge that overwrites deleted data with zeros
- Crash-safe append-only log with checksumming
- Native Rust API with Python HTTP client and Node.js bindings
- MCP server integration for editors and AI agents
- WARM Cloud sync, backup and verification without server access to keys or documents
| - Knowledge Graph on every plan including free tier
- Hybrid semantic and full-text search with reranking
- 18 Typed MCP Tools across 8 AI agents and editors
- TypeScript and Python SDKs with full REST API
- Team collaboration with roles and permissions
- Row-level security isolation enforced by database
- Agent Skills for reusable agent behaviors
- Setup in 60 seconds with browser sign-in
|
|---|
| 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
| - Graph memory included on free plan, competitors charge $249/mo for it
- First paid tier at $19/mo with 50,000 memories and 1,000 daily searches
