AI art has flooded portfolio sites, print marketplaces, social feeds, and even gallery submissions. For artists, buyers, moderators, and fans, one question keeps coming up: is this piece actually drawn by a human, or generated by a model like Midjourney, DALL-E, or Stable Diffusion? Photographs and digital paintings hide AI in different ways, so spotting AI-generated art takes a slightly different eye than spotting a fake photo.
This guide focuses specifically on illustrations, paintings, and drawings, the creative work where "AI or human?" matters most. If you are working with photos instead, start with our guide on how to spot AI-generated images.
Key Takeaways
- Look for logic, not just beauty. AI art is often gorgeous but internally inconsistent, brushwork and details that don't follow any real technique.
- Signatures and text are a fast tell. Generated art frequently includes smeared "signatures" and gibberish lettering.
- Style-averaging is a red flag. AI blends many artists into a glossy, generic look with no consistent personal voice.
- Process is proof. Real artists can show sketches, layers, and timelapses; AI output has none.
1. Inspect the Brushwork and Linework
Human painters and illustrators make consistent, intentional marks. AI mimics the appearance of brushstrokes without the underlying logic. Zoom in and look for strokes that start and stop nowhere, texture that looks "painted on" uniformly across unrelated surfaces, and detail that is suspiciously even, with no areas of rest where a human would naturally simplify.
2. Hunt for Garbled Signatures and Text
Because models train on countless signed artworks, they often hallucinate a "signature" in a corner, a smear that resembles handwriting but spells nothing. Any text inside the piece (book spines, posters, captions, runes) tends to dissolve into convincing-looking nonsense. Real lettering is consistent; AI lettering breaks down on close inspection.
3. Check Anatomy and Object Continuity
The classic giveaways from photo detection apply doubly to illustration, where the model has even more freedom to drift: hands with the wrong finger count, jewelry that changes design from one ear to the other, straps and belts that vanish behind a figure and reappear in the wrong place, and background architecture that cannot physically exist.
An AI-generated digital painting. Note how dramatic and detailed it looks, yet the structures and lighting don't fully hold up under scrutiny.
4. Watch for Style-Averaging
A defining trait of AI art is that it "averages" its training data into a polished, recognizable house style, ultra-detailed, high-contrast, slightly plasticky, and oddly generic. A human artist's body of work shows a consistent personal voice and deliberate choices; AI portfolios often show wild stylistic range with no through-line, because each image is an isolated prompt.
5. Ask About Process and Provenance
The single most reliable check has nothing to do with pixels. Genuine artists can show work-in-progress: rough sketches, layered files, undo history, timelapse recordings, reference photos. AI-generated pieces have no such trail. On marketplaces and commissions, asking for process files quickly separates the two.
6. Use Reverse Search and a Detector
Run the image through a reverse image search to see whether it traces back to a known artist or appears suddenly across stock-style listings. Then confirm with a tool: our AI image detector analyzes the underlying pixel patterns that generators leave behind, regardless of whether the piece is a photo or a painting. Treat the score as strong supporting evidence alongside the visual checks above.
Why It Matters for Artists and Buyers
Undisclosed AI art raises real stakes: contest fraud, mislabeled "handmade" listings, scraped styles passed off as original, and devalued commissions. Knowing the tells protects both the integrity of the work and the people paying for it.

Frequently Asked Questions
How can you tell if a drawing is AI-generated?
Look for inconsistent linework, garbled signatures or text, anatomy errors (especially hands), and a glossy "style-averaged" look. Ask the creator for sketches or layered process files, which AI cannot produce.
Can AI art detectors tell the difference between AI and human illustration?
Yes, to a degree. Detectors analyze pixel-level statistical patterns left by generators and work on illustrations as well as photos, but they return a probability, not certainty. Pair the score with manual checks.
Is it illegal to sell AI art as handmade?
Misrepresenting AI-generated work as original handmade art can violate marketplace rules and consumer-protection laws in many regions. Disclosure requirements vary, so check the platform's policy.
What is the most reliable single check?
Provenance. A real artist can demonstrate their process; an AI image cannot. When authenticity matters, ask to see the work in progress.
Spotting AI art is a skill that sharpens fast once you know where to look. Combine a close eye for brushwork and continuity with a provenance question and a detector score, and you'll catch the overwhelming majority of generated pieces, then confirm any doubt with our AI image detector.
