Product Vision

Brain OS is a biologically-inspired, central cognitive engine — the persistent memory and mediation layer between AI tools and the user’s world.

The vision in one sentence

Your AI tools share one localized, ever-growing memory that runs 24/7 on your machine — and they all play by the same rules.

Core principles

  1. Local-first, always — Your data never leaves your hardware. There is no account, no cloud, no telemetry.
  2. One capability ontology — A capability is a typed entry in one registry. CLI, HTTP, MCP, and the reasoner are faces over it.
  3. Memory that earns its place — Importance scoring, forgetting curves, and consolidation keep the signal sharp.
  4. Fail safe, never silently — Every error path is explicit. Degraded-but-functional is the target.
  5. Open to any LLM — Ollama, OpenAI, OpenRouter, or any OpenAI-compatible endpoint.

What Brain is not

  • A cloud service
  • A platform integration hub
  • A consumer product with a polished GUI
  • A replacement for tool-specific context windows

The web UI at /ui is a diagnostic tool for power users, not the primary interface.
