How it works

Three steps from file to verdict.

Upload your video

Drag and drop or browse for MP4, MOV, WEBM files, up to 200 MB. No technical setup. Agree to the terms and get a verdict in under a minute.

AI-powered analysis

The detector runs a deep scan across several forensic and biological signals at once.

Facial
Blink patterns, micro-expressions, and lip-sync consistency
Motion
Motion artifacts and temporal inconsistencies across frames
Generators
Fingerprints matched against HeyGen, Sora, RunwayML, and more

Get your verdict

A verdict, a detection summary, and a confidence score, with an overview of the suspect regions detected in the file.

Likely Synthetic (High) means strong evidence of AI manipulation. Likely Synthetic (Low) suggests further review. Real (no AI) means no synthetic media was detected.

Where it is used

Who uses the deepfake video detector.

Six teams that verify a video before the decision that follows.

Financial services

Banks & financial institutions

Verify customer-verification videos, reduce impersonation fraud, and strengthen identity checks during onboarding and high-value transactions.

Security

Enterprise security teams

Catch deepfake videos before they become part of phishing attempts, executive impersonation scams, or internal security incidents.

Investigations

Law enforcement agencies

Review suspicious digital evidence and identify videos that show signs of synthetic manipulation during investigations.

Identity

KYC verification teams

Improve digital onboarding by identifying face swaps and AI-generated identity videos before they enter verification workflows.

Media

News & media organizations

Confirm the authenticity of user-generated videos before publication and reduce the risk of spreading manipulated content.

Compliance

Compliance & risk teams

Add another layer of verification to existing fraud-prevention processes and strengthen trust across business operations.

Why it matters

Why this detection matters.

Deepfake video has moved from novelty to a working fraud tool. The losses are documented.

In 2024, a finance worker at a Hong Kong multinational joined a video call where every colleague on screen, including the CFO, was a deepfake. He approved 15 transfers worth roughly $25.6 million before anyone realized the only real person on the call was him.

The FBI has warned that criminals now use generative AI to make these schemes more convincing and easier to run at scale. A recorded video that looks and sounds right is no longer proof that the person on it is real.

Verify the video before you act on it.
