Mission

Understanding, not surveillance.

Every AI conversation runs on physical infrastructure you never see. Carbon Canvas makes that relationship visible — from the metadata alone. We count sessions, time, and activity size in your browser. The words themselves are discarded on the spot.

We measure

  • Which AI tool, and when
  • How long, and how often
  • The model, when the page shows it
  • An estimate of activity size

We never touch

  • Your prompts
  • The AI’s replies
  • Your files and documents
  • Anything you type, anywhere
The product

One session, fully accounted for.

Every tracked session becomes a receipt: what ran, for how long, and what it likely cost the grid — always as an honest range, with the confidence to match.

Simulated data. Your real dashboard is built from your own metadata — and only your metadata.

Transparency over simplicity

Every number shows its work.

Our estimation pipeline is versioned, sourced, and public: energy bands anchored to peer-reviewed measurement, datacenter overhead from industry surveys, and a written record of what we deliberately don’t claim. When the research moves, the version number moves with it.
