Does Google have an AI image detector?

Not as a standalone consumer tool. Google has a few related pieces, none of which is a "drop an image, get yes or no" detector you can point a stranger at.

SynthID

An invisible watermark Google embeds in images generated by its Imagen models. Google's own SynthID Detector can verify whether an image carries the watermark, but it only works on Google-generated images that still have the watermark intact. It does not work on Midjourney, DALL·E, Flux, or anything not stamped by Google.

"About this image"

A feature in Google Search and Google Lens that shows where an image has been seen before on the web and what news outlets have said about it. Useful for spotting an image being reused out of context, but it does not classify images as AI vs real.

Google Search reverse-image

Drag an image into Google Images and Google shows visually similar matches. Helpful for finding the original source if one exists. Does not directly answer "is this AI?".

What you can do right now.

If your goal is to find out whether a specific image was generated by AI from any major generator (not just Google's), use a focused third-party detector. Our free checker runs in seconds, requires no signup, covers Midjourney, DALL·E, Flux, Stable Diffusion, Imagen, and Adobe Firefly, and tells you whether the verdict came from verifiable image data or from visual analysis.

You can also combine it with Google's "About this image" to check the context: if the image has been on the web for years on reputable sites, it is more likely a real photograph that has been reshared. If it is brand new and shows up only on social posts, that is consistent with (though not proof of) AI generation.

FAQ.

Why doesn't Google have a public AI image detector?
Building a robust AI image detector that works across every generator is hard. Google has chosen to invest in provenance standards (SynthID for their own outputs, plus C2PA support in some products) rather than building a public classifier that competitors could probe and try to evade. Third-party tools like ours fill the gap by combining provenance reading with visual analysis.
Can SynthID detect non-Google AI images?
No. SynthID is a watermark that Google embeds in images generated by their own models. It cannot tell you anything about images generated by Midjourney, DALL·E, Flux, Stable Diffusion, or anything else.
Will Google Search ever tell me "this image is AI"?
"About this image" surfaces context (where the image appears, when it first appeared, what news outlets say). It is occasionally helpful for spotting AI images that have been widely flagged, but it is not a direct AI detector.
What if I find an image with the SynthID watermark?
That image was generated by a Google model (most likely Imagen). The watermark is intentionally hard to remove without destroying the image, so its presence is strong evidence of AI origin. Our detector reads SynthID markers as one of several signals.

Frequently asked.

Does Google have an AI image detector I can use?
Not as a standalone consumer tool. Google has SynthID (a watermark on Google-generated images), "About this image" (web context tool), and reverse image search, but none of these is a direct "is this AI?" detector. Third-party detectors like ours cover the gap.
Does SynthID detect non-Google AI images?
No. SynthID is a watermark Google embeds in its own model outputs (mainly Imagen). It cannot tell you anything about Midjourney, DALL·E, Flux, or Stable Diffusion outputs.
Will Google Search ever directly flag AI images?
"About this image" surfaces context, not classification. It tells you where else an image has appeared on the web, which is occasionally useful but is not a direct AI detector.
What if I find an image with the SynthID watermark?
That image was generated by a Google model. The watermark is intentionally hard to remove without destroying the image. Our detector reads SynthID markers as one of several signals.
