Common questions.
Is Witness free?+
Yes — the web scanner is free to use, no account required. Higher-volume use, mobile, and enterprise features will be available on paid plans.
What happens to my image after I scan it?+
Witness processes your image to produce a verdict, then deletes it. Images are processed in ephemeral containers and never stored. We never share, sell, or train models on your uploads.
How accurate is Witness?+
Witness combines multiple detection models, each with strong published accuracy on standard benchmarks. Accuracy varies by image type — Witness shows its confidence so you know how much weight to give the result.
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.
