AI Image Detector

Check the evidence left inside an image

Find out whether an image was made with AI from the provenance and metadata stored inside the image file. Instead of guessing from how the image looks, this tool reads whether the evidence is actually written there.

Your image is never sent anywhere. Everything is checked inside this browser.

What this tool checks

Besides the photo or picture itself, an image file has places where the story of how it was made can be written. This tool reads the following four.

Provenance (C2PA / Content Credentials)

An international standard that embeds the history of how an image was created and edited, with a digital signature. If the signing organization is on the C2PA trust list and the image has not been altered since it was signed, the record can be verified as authentic. If that record also shows AI generation or editing, the tool shows "This image was made with AI". If the signing organization cannot be confirmed, it stops at "may have been made with AI".

IPTC digital source type

A metadata standard used for news photos and similar images has a value that means "generated by AI" (trainedAlgorithmicMedia). Because it carries no signature, it is treated as "may have been made with AI".

Generation parameters embedded in the PNG

Some image generators that run on your own computer write the prompt and settings into the PNG. If these are found, the tool shows "may have been made with AI".

Software and creator tool fields

The field that holds the name of the software that saved the image sometimes contains the name of a generator. This is also treated as "may have been made with AI".

The three kinds of results

The tool does not give a number like "X% AI". Depending on how reliable the records it finds are, it shows one of the following three.

This image was made with AI

Confidence: Certain (confirmed by signature)

Shown when the image contains a record saying it was made or edited with AI, signed by an organization that can be checked against the trust list.

This image may have been made with AI

Confidence: Possible (unverified information)

Shown when there are traces of AI, such as generator settings or a tool name, but only in information anyone can add.

We couldn't tell whether this image was made with AI

Confidence: Nothing to go on

Shown when no record we can base a judgment on is found. Most images posted on social media and most screenshots end up here.

What this tool can't tell you

  • It cannot identify images whose records have been removed, or images from generators that never add records in the first place.
  • Invisible watermarks (such as Google's SynthID) require dedicated detection methods and cannot be read by a browser alone.
  • The information behind a "may have been made with AI" result has no signature, so people can add it themselves.
  • "Couldn't tell" does not mean the image was not made with AI.

Visual clues

When no evidence is found, looking closely at the details can sometimes give you a clue. However, image generation keeps getting better, and none of these is conclusive.

  • Do the number and shape of hands and fingers, or the way accessories connect, look unnatural?
  • Does text on signs or clothing form readable letters?
  • Do things that should match on both sides (glasses, earrings, etc.) differ from each other?
  • Do shadows and reflections point in a direction consistent with the light?
  • Do straight lines in the background (pillars, window frames) bend or break partway?

Privacy and safety

  • Your image is not sent to a server. All reading happens inside the browser that has this page open.
  • Results are not sent to analytics or anywhere else either.
  • The tool does not connect to external URLs written in the image (including provenance references).
  • The component that verifies provenance signatures (about 9MB) and the trust list are loaded from this site only when the image contains provenance.
  • The trust list from the C2PA Conformance Program (CC BY 4.0) and the certificate usage settings from the Content Authenticity Initiative (Apache-2.0) are copied to and used from this site.

FAQ

I got "We couldn't tell whether this image was made with AI". Does that mean it isn't AI?

No. It only means no records were found. Images posted on social media and screenshots have almost always lost their records.

If it says "This image was made with AI", is that certain?

It is certain that a signed record states AI generation or editing and that it has not been altered since signing. However, how much AI was involved (whether the whole image was generated or only part of it was edited) depends on what the record says. Check the original text in the evidence section.

Is my image stored anywhere?

No. Your image is not sent to this site's server or anywhere else.

Does it work on a phone?

Yes. Only for images that contain provenance (C2PA), it loads a component of about 9MB the first time.

Can I check an image by entering its URL?

No, that isn't supported. Having the server fetch external images poses security problems, so please save the image first and then add it.
