  1. It reads what you already see

    Only content your browser already received as part of your own browsing. Nothing extra is fetched to build a dataset.

  2. It checks on your device

    Signals such as posting rhythm, duplicated text and image traits are computed locally.

  3. It labels with evidence

    Likely human, likely automated, or likely AI-generated, each with the reasons attached.

  4. You stay in charge

    Tune sensitivity, hide labels, opt in or out of sharing, and dispute anything.
