AI Detector Tools for Images, Metadata, and Text

The browser tools are free. They run on Numen's private Mac server and delete each check after processing. The iPhone and Mac apps do the same work on-device. Use the general checker if you are not sure where to start. For a narrower check, pick ChatGPT, Gemini, Flux, Stable Diffusion, SynthID, C2PA, IPTC, deepfakes, or AI text.

  • You can testPhotos, screenshots, product images, receipts, and profile pictures up to 8 MB.
  • ResultA probability verdict, AI score, and source details when the file carries them.
  • PrivacyDeleted the moment the check finishes. We never keep your photo.

AI detection is probabilistic. Results can vary with new AI models and evasion methods. A real photo edited with AI tools can be flagged as AI.

Online checks are deleted after processing.

Image Model Detectors

Model-specific pages for people checking ChatGPT, Gemini, Midjourney, Firefly, Stable Diffusion, Flux, or an unknown AI image source.

Generic image check

AI Image Detector

Use Slop or Not as an AI image detector when the source is unknown. It checks SynthID, C2PA/IPTC metadata, and pixels before reporting a result.

Open detector pageOpenAI image checks

ChatGPT Image Detector

Free ChatGPT image detector and checker. Slop or Not reads OpenAI C2PA and SynthID watermark signals, then checks the pixels. No account needed.

Open detector pageGoogle image checks

Gemini AI Image Detector

Check whether a photo came from Nano Banana or Gemini image generation. Slop or Not reads Google SynthID and C2PA/IPTC metadata, then checks the pixels.

Open detector pageOpen model checks

Stable Diffusion AI Image Detector

Check images that may come from Stable Diffusion. Slop or Not looks for metadata and visual generator signals without requiring an account.

Open detector pageFlux image checks

Flux AI Image Detector

Check images that may come from Flux image models. Slop or Not reviews metadata when present and image signals when provenance is missing.

Open detector pageMidjourney image checks

Midjourney AI Image Detector

Check whether an image looks Midjourney-generated. Slop or Not scans the pixels with a trained classifier and reads any provenance the file carries.

Open detector pageFirefly image checks

Adobe Firefly Detector

Check whether an image came from Adobe Firefly. Slop or Not reads Firefly Content Credentials (C2PA), then checks the pixels when metadata is stripped.

Open detector page

Watermark and Metadata Detectors

Pages for SynthID, C2PA, IPTC, and other AI watermark or metadata checks.

Watermark checks

AI Watermark Detector

Use this AI watermark detector to check images for SynthID, C2PA Content Credentials, and IPTC metadata before pixel detection.

Open detector pageWatermark checks

SynthID Watermark Checker

Free SynthID detector: check an image for Google and OpenAI SynthID watermark signals online, or run the check on-device on iPhone and Mac.

Open detector pageContent Credentials

C2PA Detector

Use this C2PA detector to check Content Credentials with Slop or Not. It reads signed provenance, then checks pixels when credentials are absent.

Open detector pageMetadata checks

IPTC Metadata Detector

Check IPTC metadata and AI provenance fields in images. Slop or Not reads metadata when available and falls back to AI image detection.

Open detector page

Deepfake Checks

Still-image checks for profile photos, portraits, and suspicious identity images.

Face and identity checks

Deepfake Photo Detector

Use this free deepfake detector to check photos, portraits, and profile pictures for AI-generated faces. Online checks are deleted after processing.

Open detector page

Text Detection

Writing checks for essays, reviews, resumes, messages, and other pasted text.

Writing checks

AI Text Detector

Check whether writing looks AI-generated with Slop or Not. Paste text online for a quick check, or use the iPhone and Mac apps on-device.
