Midjourney image checks

Midjourney AI Image Detector

Midjourney images rarely carry readable provenance, so this Midjourney detector leans on visual evidence. Slop or Not scans the pixels with a classifier trained on millions of AI and human images, notes when provenance is absent, and keeps online uploads away from outside AI companies.

The only AI image detector that reads Google DeepMind's SynthID watermark from both Google and OpenAI images.

Google's own detector checks only Google's images. OpenAI's checks only OpenAI's. Slop or Not reads both.

  • 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.

What it checks

Check Midjourney-Style Images When No Watermark Exists

Whole-image classifier evidence, reported as an AI-likelihood score rather than a named generator

Missing C2PA or SynthID provenance, which fits how Midjourney images usually travel

Metadata left behind by editing or upscaling apps when the file carries it

Good Uses

  • Checking concept art or illustrations before licensing them
  • Reviewing photorealistic portraits from unknown accounts
  • Screening marketplace and portfolio images for undisclosed AI use

Limits to Know

  • Midjourney does not embed a watermark Slop or Not can verify, so results are probabilities, not provenance matches
  • Heavy edits, crops, or recompression can weaken the visual evidence
  • A polished real photo can resemble Midjourney output after filters

FAQ

Midjourney AI Image Detector Questions

Can Slop or Not detect Midjourney images?

It scores the image for AI likelihood using a classifier trained on millions of AI and human images. Because Midjourney does not embed a watermark Slop or Not can verify, the result is a probability rather than a provenance match.

Do Midjourney images have a watermark or metadata?

Not one Slop or Not can verify. Midjourney images typically arrive without readable C2PA Content Credentials or SynthID signals, so the absence of provenance is itself a common trait of Midjourney files.

When should I use the general AI image detector instead?

Use the Midjourney detector when Midjourney is the suspected source. Use the broader AI image detector when the generator is unknown or the image could come from ChatGPT, Gemini, or an open model.
