Sinain — The Ambient Intelligence
Eyes and ears for your AI agents and your teammates.
A private Context OS that captures your screen and audio, distilling them into a structured knowledge graph — accessible from MCP, a web UI, an invisible HUD overlay, and shareable peer-to-peer between users. MIT-licensed.
Hey Product Hunt,
I'm Igor. I built Sinain because feeding context into AI agents
became more time-consuming than the work itself. My fleet of
agents grew, the inbound signal grew faster, and I kept losing
5 minutes at the start of every coding session re-pasting old
decisions, screenshots, and notes into the prompt. So together
with my team, we built a tool that gathers it live from your
screen and audio, distills it into a private knowledge graph,
and serves it to any MCP-compatible agent.
Worth knowing:
Privacy-first: Default mode uses OpenRouter (token usage tracked).
Paranoid mode runs entirely on-device with Ollama + whisper.cpp —
zero network at runtime. The HUD overlay is invisible to screen
capture, so it never appears in recordings or screen shares.
Benchmark: 82.8% IPR on LongMemEval (ICLR 2025)
Sharing: Knowledge sharing between users is peer-to-peer over
WebRTC. The recipient's machine pulls from yours directly; their
agents inherit the context through the same MCP.
For now: macOS only (Windows on the roadmap). MIT-licensed.
