Major product launches, capability updates, and security proofs for sovseal — one private memory across every AI you use.

​
2026-07-29 — 70% Extension Footprint Reduction & Opt-In Fact Extractor (v0.4.1 / v1.190.0)

Unbundled the optional 283 MB fact-extraction model from the Chrome extension package (@sovseal/extension), shrinking the packed extension artifact from 344.1 MiB to 100.3 MiB (−70.8%).
  • Zero-Network Default Memory: Core store and recall execute 100% offline on-device with zero network calls via the bundled ONNX embedder (intfloat/multilingual-e5-small).
  • Opt-In WebGPU Extractor Download: Local fact distillation (LFM2.5-350M @ 283 MB or Qwen2.5-1.5B @ 1.2 GB) downloads lazily only on user request, verified against SHA-256 digests over Hugging Face CORS with zero host permissions.

​
2026-07-28 — Real-Time Memory Inspection & Zero-Passphrase Unlock (v5.54.0 / v1.191.0)

Overhauled the dashboard (app.sovseal.com) into 5 benefit-oriented core routes (/home, /plan, /proof, /devices, /settings) with zero-knowledge local inspection capabilities.
  • Zero-Passphrase Local Companion Unlock: The dashboard Memories page talks to the locally-installed Chrome extension over an origin-scoped bridge (app.sovseal.com) to decrypt memories client-side without entering a passphrase.
  • Interactive Public Sandbox (/playground): Unauthenticated live demonstration executing real Web Crypto AES-256-GCM encryption/decryption in browser memory without sending keys or unencrypted data to any server.
  • Falsifiable Security Proofs (/proof): Interactive Packet-Capture Guarantee panel and SHA-256 tamper-evident audit ledger verification.

​
2026-07-02 — OS Keychain Key Custody & PII Redaction Middleware (v0.3.5 / v0.3.6)

Migrated master encryption keys from local plaintext config files into native OS Keychain storage (macOS Keychain, Windows Credential Manager, Linux libsecret).
  • HKDF Cryptographic Domain Separation: Derives subkeys k_rest = HKDF(master, "sovseal/at-rest/v1") and k_sync = HKDF(master, "sovseal/sync/v1") transiently in memory so at-rest storage and sync payloads are cryptographically isolated.
  • Automated Client-Side PII Redaction: Pre-vectorization masking for SSNs, Luhn-validated credit card numbers, and provider API keys before storage or embedding derivation.
  • Vector Retention TTL: LanceDB epoch-ms timestamping with 24-hour local sweeps and 7-day server grace period purges to satisfy GDPR erasure mandates.

​
2026-05-31 — Real-Time Memory Observability & Dashboards (v5.6.0)

Launched the initial SaaS dashboard (apps/dashboard) for monitoring agent memory volume, vector recall operational metrics, and zero-knowledge synchronization state.

​
2026-05-12 — Zero-Knowledge Local MCP Memory Server (v0.3.0 / v5.0.0)

Officially launched @sovseal/mcp-server to npm, providing an unkillable, zero-knowledge memory node for local AI clients (Claude Desktop, Cursor, etc.).
  • Frictionless 0-Config CLI Setup: npx -y @sovseal/mcp-server connects AI assistants immediately without cloud accounts or API keys for local operation.
  • Client-Side AES-256-GCM Encryption: All memory payloads are encrypted on your device prior to sync. Plaintext never leaves your machine.
  • Falsifiable Security Guarantee: Verifiable by packet inspection (Wireshark / mitmproxy). Cloud endpoints receive ciphertext only.
