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.
Individual: $10/month. Team: $15 per user per month. Enterprise: Custom pricing. All plans start with 14-day free trial.
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
Connect any MCP client
Space-based access control with owner, editor, and viewer roles
Version history on every memory
Per-memory attribution and provenance tracking
Row-level security in Postgres
Topic-based organization within Spaces
Works with Cursor, Claude Code, Copilot, ChatGPT
Priority support on Team and Enterprise plans
Personal and Shared Spaces
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
Tool-agnostic across mixed AI stacks instead of locked to one vendor
Works across teams without copy-paste or re-explaining context
Person-first design where everyone maintains their own knowledge slice
Single-team pricing with no enterprise minimum
Shared control through role-based permissions and governance
