Anyone can now produce a photograph of something that never happened, a video of someone saying words they never said, and a voice note in a relative's voice. VTYAI examines a file the way a forensic analyst would, then explains what it found in language you don't need a background in imaging to follow.
Every check is free, no account needed. You get a verdict, a confidence figure, and — more importantly — the list of reasons behind both, so you can weigh the evidence yourself rather than trusting a number.

Methodology
What we actually look at, and where the method runs out.
There is no single test that separates a real photograph from a generated one. What exists is a set of partial signals, each easy to fool on its own, that become persuasive when several independently point the same way. A check here runs through four layers and reports each one, including the ones that came back inconclusive.
Step one
The file's own record
Cameras write down what they did: model, lens, exposure, timestamps, sometimes location. Editors and generators leave their own marks, and newer files can carry content credentials describing every step. Contradictions here are the strongest evidence there is — a file claiming a camera that never produced that resolution has been through a pipeline nobody mentioned.
Step two
Compression and resave history
Every save stacks another compression layer onto an image. When one region has been compressed a different number of times than its surroundings, something was pasted in. Heavily reposted files lose this trail entirely, which is why we say so instead of guessing.
Step three
Texture, light and noise
Real sensors produce uneven grain, heavier in shadows than highlights. Generated imagery is often too clean, repeats fine detail, and gets reflections and shadow directions subtly wrong. For video and audio we add movement and voice: lip closures on plosives, breathing, room ambience, and physics that momentum should obey.
Step four
Reasons, not just a score
Each check can fail on its own, so a single percentage hides more than it explains. VTYAI lists what it examined, what looked normal, what looked wrong, and how much weight that deserves — so the judgement stays yours.
Known limits
Screenshots, heavy re-compression and aggressive phone beautification all produce artefacts that resemble generation, and a careful forgery can pass several checks cleanly. When the evidence is thin, the verdict says so rather than inventing confidence. Treat any result as one input to a judgement, alongside where the file came from and who is circulating it.

Questions we get
Common questions
- How do I know if a photo is AI-generated?
- Upload it here. VTYAI looks at the file's hidden data, compression history, lighting and texture patterns, then tells you in plain English whether it looks AI-generated, edited, or authentic — and what made it think so.
- Can VTYAI check video and audio too?
- Yes. Photos, video clips and audio recordings up to 18 MB are all supported, including checks for synthetic voice and face-swap artifacts.
- Is it free?
- Every check is free and supported by ads, with no account required. A paid ad-free plan is available for people who use it often.
- Is the result proof?
- No. No detector is perfect. VTYAI gives you an evidence-based opinion with the reasons behind it, so you can judge the content yourself rather than trusting a single score.
- What happens to the file I upload?
- It is analysed and discarded. Files are not published, sold, or used to train anything. The privacy policy sets out exactly what is kept and for how long.
