Open model checks
Stable Diffusion AI Image Detector
Stable Diffusion images often leave no signed proof. Slop or Not looks for prompt or model metadata first, then scores the pixels with a classifier trained on millions of human and AI images when no readable provenance or watermark resolves the file. Online checks stay 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.
What it checks
Detect Stable Diffusion Images When Metadata Is Missing
Generation hints in EXIF, PNG text chunks, or app metadata
Texture and anatomy artifacts common in diffusion outputs
Visual classifier output when the file has no provenance
Good Uses
- Checking marketplace or portfolio images
- Screening assets before accepting them from freelancers
- Reviewing images from open model communities
Limits to Know
- Many Stable Diffusion workflows strip or never write metadata
- High-quality LoRA or fine-tuned outputs may be harder to flag
- Human edits after generation can blur the signal
FAQ
Stable Diffusion AI Image Detector Questions
How do I detect Stable Diffusion images?
Upload the image to the free online checker or open it in the Slop or Not app. The detector looks for prompt or model metadata first, then scores the pixels for diffusion traces, so you get an answer even when the file carries no provenance.
Does Stable Diffusion always add metadata?
No. Some Stable Diffusion tools write prompt, model, or sampler details into image metadata, while many exports strip that data. Slop or Not checks both metadata and the pixels.
Can it identify the exact checkpoint?
No. The detector is built for authenticity checks, not exact checkpoint attribution. It reports AI likelihood and visible evidence rather than naming every model variant.
Is this useful for Midjourney too?
Use the dedicated Midjourney AI image detector when Midjourney is the likely source, and the general AI image detector for unknown generators. Use Stable Diffusion detection when an open-model workflow is the likely source.
Run the Next Check on Your iPhone or Mac
The Slop or Not app checks images and text on-device, so nothing you check ever leaves your device.

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.
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.
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.
