Basic: €9/month (first month €0.90), 20 credits monthly. Pro: €19/month (first month €1.90), 80 credits monthly. Extra credit
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
End-to-end encryption with XChaCha20-Poly1305
One-time download only, then automatic destruction
Supports files up to 1 TB
Password protection included by default
Integration with Claude, Cursor and Claude Desktop
API key support for CI and scripts
Resumable uploads for large files
No readable file contents stored by service
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
Files encrypted on sender's device before upload
Automatic permanent destruction after one download
No recovery possible by design
Repeated wrong password attempts destroy the transfer
