Why People Use It
CheckThatPhoto is useful when you need a quick, no-cost signal on whether a photo was AI-generated before sharing, buying, or publishing it. Unlike paid authenticity services, it emphasizes transparency about its limits and does not sell results as legal proof. The guest-check model makes it accessible for one-off verification without creating an account.
