One drop. One verdict.
Witness runs your image through a stack of detection models. You get a single answer, in language you can act on.
You drop in an image or video
JPG, PNG, or MP4. Drag, paste, or upload. Videos over 30s get a trimmer.
Witness checks it from every angle
Multiple detection models analyze images and videos in parallel.
You get a clear verdict
Real, Synthetic, or Uncertain — with a confidence score and a plain-language explanation.
Made for moments
that matter.
Journalists and fact-checkers verifying a source image or UGC before it goes out.
Fraud and claims teams screening refund photos, damage claims, and proof-of-purchase evidence.
Trust and safety teams checking profiles, listings, and reported content at volume.
Anyone sent something that doesn't look right — a message, a profile, a viral clip.
A real answer.
Witness gives you a verdict you can act on — and shows its work.
Witness found no signatures of AI generation. The image looks consistent with a real camera, real light, real moment.
Witness found fingerprints of a generative model. Treat the image as AI-generated until you have a reason not to.

Is Witness free?+
Yes — 5 image scans per day with no account required. Create a free account for 15 images and 1 video per day. Pro is $15/month for unlimited images and 30 videos per month.
Does Witness work on videos?+
Yes. Upload a video on the web app. Witness uses specialized video detection models that look for temporal deepfake artifacts across the video.
Can I use a Witness verdict in court?+
Witness is a strong first signal, not certified forensic evidence. For legal proceedings, pair a Witness scan with a qualified digital forensics expert.
Why is it called Witness?+
Because that's what you become when you can tell the difference. A witness sees clearly and says what they saw.
