Witness AI

Witness is a deepfake detection tool that checks images and videos for AI generation. It uses an ensemble of multiple detection models running in parallel to analyze media from every angle, then returns a clear verdict: AI or real.

What makes Witness different:

• Ensemble detection: multiple models check each image, not just one. More signals, fewer false positives.
• Chrome extension: right-click any image on any website to check it. Works on Twitter/X, Instagram, Reddit, and everywhere else.
• Video detection: upload a video and Witness checks it for face swaps, AI-generated content, and temporal manipulation.
• C2PA provenance reading: checks for cryptographic content credentials before running statistical models.
• Privacy-first: images are analyzed and immediately discarded. Nothing is stored.

Free tier: 5 image scans per day with no account. Create a free account for 15 images and 1 video per day. Pro is $15/month for higher limits.

Built for anyone who needs to verify what they see online: consumers checking suspicious content, parents protecting their families, journalists verifying sources, and enterprise teams screening claims and evidence.
