Instant Verdict

Clear AI-likelihood score with a breakdown of every signal.

Simple by design

How the detector works

Three steps. Under a minute. Zero technical knowledge required.

01

Upload your video

Drag and drop any MP4, MOV or WEBM file up to 200MB. It stays on your device — nothing is sent anywhere.

02

Heuristic scan runs

The engine reads metadata, samples frames, and measures motion smoothness, temporal consistency and compression patterns.

03

Get your verdict

A clear AI-likelihood score with a per-signal breakdown — likely AI, likely human-made, or uncertain.

Under the hood

What the scan actually checks

Four independent heuristic signals, combined into one score.

🌫

Motion smoothness

AI video often moves too perfectly — unnaturally fluid motion with none of the micro-jitter real cameras produce.

🧠

Temporal consistency

Frame-to-frame sampling reveals objects that morph, flicker or subtly change — classic tells of generated footage.

📷

Compression artifacts

Real camera footage compresses differently than synthetic frames. Artifact distribution is a strong statistical signal.

📄

File metadata

Container data, encoder tags and creation fingerprints often reveal which tool — camera or generator — made the file.

Frequently asked questions

Yes — 100% free, forever. There are no credits, no paywalls and no watermarks on your results. Upload any MP4, MOV or WEBM video up to 200MB and scan it as many times as you like.

No. There is no sign-up, no login and no email required. Open the page, drop your video in, and press Scan Now.

No. Every scan runs locally in your own browser — your file never leaves your device. Nothing is stored, logged or shared, which is why the tool stays fast and private.

It runs a heuristic analysis: it reads the file metadata, samples frames, and measures signals associated with synthetic media — motion smoothness, temporal consistency, compression patterns and frame-level artifacts. The signals are combined into an AI-likelihood score.

It is a heuristic estimate, not a forensic proof. Modern AI video is extremely convincing, and no automated tool is 100% certain. Treat the verdict as a strong signal and combine it with your own judgment — especially for high-stakes decisions.

MP4, MOV and WEBM files up to 200MB. Larger files are rejected before scanning so your browser stays responsive.

Yes. The whole site is mobile-responsive — the upload area, scan animation and verdict meter all work on phones and tablets.
