These sites investigate widely circulated claims and determine how well they match the available evidence. They focus on rumors, viral social-media posts, political claims, scams, urban legends, manipulated images and quotations, and other possible misinformation.
These sites are good at detecting misrepresented or altered existing photographs. They are less useful when an image is completely new—such as a newly generated AI image. They can reveal several kinds of deception:
An image claimed to be from a recent event may appear online years earlier.
The original may show that part of the photograph was cropped out.
An older, unedited version may reveal that something was added or removed.
The image may come from a completely different location or event.
These free sites have a fairly good record at determining if video, images, or audio is fake or not. They are not perfect (but no fake detection system is perfect).
These free tools examine a single image for signs of manipulation or AI generation — inconsistent lighting and noise, edited regions, and telltale artifacts. Useful for images that never existed before, which reverse image search can't find.
These free tools analyze a voice recording for signs that it was synthesized or cloned rather than spoken by a real person. Like all detectors they are imperfect, and short or low-quality clips are the hardest to judge.
