Deepfake verification
Check faces, voices, and motion for deepfake-style manipulation.

About this check
What Deepfake Detector actually does.
The Deepfake Detector is the cross-modal entry point for face-swap, voice-clone, and full-body synthesis checks. Upload a clip or paste a link, and the engine reports the same Truth Score format used across checkreal.ai, with deepfake-specific signals on facial motion, lip-sync, and scene continuity.
How it works
- 1Facial-landmark stability tracks how the face moves between frames against a coherent 3D head model.
- 2Lip-sync alignment compares mouth shape against the audio phoneme over time.
- 3Scene continuity catches background warping common when only the face is generated.
When to use it
Real situations this page is built for.
- A video of a public figure is circulating that contradicts their public statements.
- An ex-partner or coworker may be the target of a non-consensual deepfake.
- A 'leaked' executive or political clip suddenly drops just before a market or news event.
Limitations
State-of-the-art deepfakes specifically tuned to evade common detectors will sometimes pass. Use this as one input alongside source-of-record verification.

Honest scope
What this detector does not do.
Naming the gaps explicitly so the score is interpreted in context.
- Whether claims made in the clip are factually true.
- Which deepfake tool produced a manipulated clip.
- Long-form video — the demo focuses on short-form sampling.
FAQ
Deepfake Detector questions
Is this the same as 'deepfake detection online'?
Yes — it is the canonical entry point. Older URLs for online deepfake checks redirect here.
Can it confirm a video is a deepfake?
No detector confirms with certainty. It reports the strength of deepfake-consistent signals, which you should combine with provenance and source checks.
Does it work on photos?
For still images use the AI Image Detector. The deepfake page focuses on video and voice combinations.
