Features

Everything you need,
nothing you don't.

Context Graph

Pages you visit form a knowledge graph. See connections between ideas, not a flat list of URLs.

Local-First Privacy

Your context graph lives on your device. No cloud sync. No tracking. Your thoughts stay yours.

Open & Extensible

Built on open standards. Extend with plugins. Fork it, shape it, make it yours.

Privacy First

Your context is sacred.

We believe your browsing context is an extension of your thinking. It should never leave your machine without your explicit consent.

Defense in Depth

40 security elements.
Zero compromises.

From hardened infrastructure to frontier AI safety, every layer is documented, auditable, and enforced by default.

CORE Infrastructure AI Safety

Infrastructure Hardening

  • E1 Process isolation & sandbox enforcement
  • E2 Memory-safe IPC with type validation
  • E3 Content Security Policy & origin isolation
  • E4 Extension permission model with capability limits
  • E5 Cryptographic update verification chain
  • E6 Automated fuzzing & vulnerability scanning
Read E1–E6 docs

Frontier AI Safety

  • N1 Prompt injection defense & input sanitization
  • N2 Model output validation & hallucination detection
  • N3 Context window poisoning prevention
  • N4 Inference resource limits & DoS protection
  • N5 Local model integrity verification
  • N6+ Embedding safety, RAG guardrails & audit logging
