AI Art Detector

Updated

An AI art detector is for artists, art directors, competition organisers and buyers who want a second opinion on whether a piece was made with an image generator. Upload a PNG, JPG or WEBP image up to 15 MB to get a probability that it is AI-generated. Art is harder to judge than photos, so treat the result as one signal.

Limitations: Every result is a probability that can be wrong, not proof of how an image was made. How results can be wrong →

How the AI Art Detector Checks an Image

The image is sent to a third-party image-analysis provider (named on the How It Works page) whose model estimates whether an image was generated by AI. The result is a probability with a label: Likely AI-Generated at 55% and above, Uncertain at 30-54%, and Likely Authentic below 30%.

The same check returns a separate face-manipulation score. On artwork it is usually less meaningful, because it is designed for photographic faces.

Why Art Is Harder Than Photos

  • Digital tools: artists use brushes, filters, 3D renders and texture packs that can look generated.
  • Mixed workflows: a human painting over an AI sketch, or AI used to upscale a hand-drawn piece, sits in between.
  • Style: flat, smooth or highly polished styles can push scores up whoever made them.
  • Compression: low-resolution copies from social media lose detail the model uses.

Better Evidence Than a Score

For commissions and competitions, process evidence is stronger than any detector: layered working files, timelapse recordings, sketches and the artist's earlier portfolio. Asking for these is a fairer way to settle a dispute than a score.

If you are an artist and your work is flagged, keep your working files and share them. A score is not proof, and false positives on human art happen.

If You Commission or Buy Art

Put your expectations in the brief: whether AI tools are allowed at any stage, and what process evidence you may ask for. Artists can then quote and work accordingly, and a disagreement later has a clear reference point.

When a delivered piece raises questions, ask for the working file or an in-progress screenshot before running any check, and treat a detector result as one input to that conversation.
