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
Hybrid vector and knowledge-graph retrieval
Zero-copy state branching and merging
44 memory tools over MCP protocol
Sub-0.4ms P99 retrieval latency
Built-in importers from Mem0, Zep, Pinecone and others
Entity deduplication and linking
Offline operation with fleet synchronization
Memory Copilot for schema generation
Object storage for multimodal state
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
Memory versioning with Git-style fork, diff and merge—test changes safely and undo mistakes
Native MCP integration: one URL works with Claude, Cursor, Windsurf and any MCP client
Seamless migration from Mem0, Zep, Pinecone and other systems without data loss
