DotCheck

See what's real.

DotCheck puts an AI score on what you see and hear. In Chrome, colored dots mark images and video as you browse. Underlines mark text. Green leans real, red leans AI. Drop a file into Check on the web, or share one from Android. The same four engines run on every plan.

If the file already carries a clear generator mark, that can lock the score before a model runs. Otherwise Vermeer, Valla, Muybridge, or Helmholtz writes the percent. A score is a signal, not a verdict. We publish the holdout tables.

Product

Everyday scoring is Check, Chrome, Android, and the Pro API. This Hub org publishes the open heads. The storefront Space does not score uploads.

No ads. Audio never turns on or uses the microphone. It analyzes audio files. We score what you send, not your browse history. Made in the EU.

Open engines

Apache-2.0 heads. Production loads the same artifacts. Architecture, training, evaluation, and limits live on each card.

Valla reads English, Chinese, Spanish, French, Portuguese, German, Italian, and Dutch.

Collection: DotCheck Engines. Registry and wiring: DotCheck/dotcheck.

When a clip has a soundtrack, the product joins Muybridge frames with Helmholtz windows into one clip score. That assembly stays in the product path. It is not a fifth open head.
