AI image detector by generator

AI image detector by generator

Every generator leaves a different trail inside the file: signed Content Credentials, an IPTC source type, a saved prompt, a watermark or nothing at all. Pick the tool you suspect and see exactly what isGenAI can reveal from the original download.

Saved prompt found

The generator wrote its settings into the file.

Prompt, negative prompt, seed, sampler and model are read word for word, with the field they came from.

Saved prompt found: where this record sits inside a PNG file and what the isGenAI report says about it. The picture is a code-drawn controlled example that carries this record; download it and check it yourself.

Choose the generator

Midjourney

Is this a Midjourney image? See what Midjourney writes into downloads (IPTC AI source type, XMP description) and what isGenAI reads from the file. Free.

DALL·E 3

Check whether an image came from DALL·E 3. OpenAI attaches C2PA Content Credentials to DALL·E 3 images; isGenAI validates the signed record.

ChatGPT Images

Was this picture made in ChatGPT? OpenAI adds C2PA Content Credentials and a SynthID watermark to ChatGPT images. See what isGenAI reads from the download.

Stable Diffusion

Check a Stable Diffusion image for the saved prompt, seed and model. isGenAI reads A1111 parameters, ComfyUI and InvokeAI records from the original PNG.

SDXL

Check an SDXL image for its saved prompt, refiner settings and model. isGenAI reads the A1111, ComfyUI and InvokeAI records written into the original PNG.

FLUX

Check a FLUX image. Black Forest Labs attaches C2PA Content Credentials to API and Playground outputs; local FLUX runs leave ComfyUI records.

Gemini and Imagen

Is this image from Gemini or Imagen? Google embeds a SynthID watermark and adds C2PA credentials to newer Gemini outputs.

Adobe Firefly

Check an Adobe Firefly image. Adobe applies Content Credentials automatically to fully generated Firefly assets. isGenAI reveals the signed record.

Ideogram

Check an Ideogram image. Ideogram publishes no provenance documentation we could find, so isGenAI reports exactly what the download contains.

Leonardo.Ai

Check a Leonardo.Ai image for Content Credentials, source types and saved prompts. No vendor provenance documentation found; see what the file holds.

Canva AI

Check an image made with Canva’s AI tools. No Canva Content Credentials documentation was found as of October 2026; see what the export holds.

Bing Image Creator

Check a Bing Image Creator image. Microsoft signals its generated images with C2PA and IPTC metadata; isGenAI validates the signed record.

Meta AI

Check a Meta AI image. Meta adds a visible marker, an invisible watermark and IPTC metadata to photorealistic Meta AI images.

Grok

Check a Grok (xAI) image. xAI publishes no provenance documentation we could find as of October 2026; isGenAI reports what the file contains.

Recraft

Check a Recraft image. No Recraft Content Credentials or source-type documentation was found as of October 2026; see what the export holds.

Krea

Check an image from Krea. Krea documents downloads but not provenance metadata; isGenAI reports the C2PA, IPTC or prompt records in the file.

NightCafe

Check a NightCafe image. No NightCafe provenance documentation was found as of October 2026; isGenAI reports the records the file holds.

Playground

Check a Playground AI image. No Playground provenance documentation was found as of October 2026; isGenAI reports which records the export has.

ComfyUI

Check a ComfyUI image. ComfyUI saves the prompt graph and workflow in PNG text chunks; isGenAI reads them and shows the saved prompt, model and settings.

AUTOMATIC1111

Check an AUTOMATIC1111 image online. The web UI saves generation parameters as a PNG text chunk; isGenAI reads the prompt, seed, sampler and model from it.

InvokeAI

Check an InvokeAI image. InvokeAI stores an invokeai_metadata record in the PNG; isGenAI reads the prompt, seed, model and generation mode from it.

Fooocus

Check a Fooocus image. Fooocus saves metadata only when enabled, in its own JSON scheme or the A1111 scheme; isGenAI reads the A1111 scheme.

NovelAI

Free NovelAI metadata reader. See the prompt, negative prompt (uc), seed, steps, sampler, scale and size saved in an original NovelAI PNG. No account.

Runway

Check a Runway Gen-4 video or image. Runway publishes no provenance documentation we could find; see what the C2PA checker reads from the file.

How to check an image from this generator

  1. Get the original download, not a screenshot or a copy saved from a chat or social feed.
  2. Upload it to the free AI image detector. Files up to 20 MiB in PNG, JPEG, WebP, AVIF or TIFF are read on the server and are private by default.
  3. Open “How we checked” and read each finding with its source field: signed record, declared source type, saved prompt, AI statement or matching copy.
  4. Treat a clean result as “no evidence found”, never as proof that a person made the picture.
