About Witness
Witness is a media verification service that examines images, video and audio for signs of synthetic creation. Users upload a file, and the system runs separate detectors for diffusion and GAN images, generated video, face swaps and cloned voices. Each scan returns a likelihood score, a heatmap or frame timeline, a list of contributing signals and an audit ID, along with checks on EXIF and C2PA data. The site says files are discarded after analysis. It targets insurers, HR teams, legal staff, newsrooms and individuals checking dating profiles. A free plan covers 20 image scans a month, while Pro costs 15 USD monthly or 120 USD per year.

Verdict
