How to Tell if Art is AI-Generated: 8 Signs to Look For

AI image generators like Midjourney, DALL-E, and Stable Diffusion have made it remarkably easy to create images that look like real paintings. Whether you're browsing art online, considering a purchase, or just curious about an image you've seen, knowing how to distinguish AI-generated art from human-created paintings is an increasingly valuable skill.

Here are 8 practical signs that an artwork may have been created by AI rather than a human artist.

1. Hands and Fingers

This remains the most reliable visual indicator. AI image generators frequently produce hands with the wrong number of fingers — six fingers, merged digits, fingers bending at impossible angles, or hands that seem to dissolve into the background. While AI models have improved significantly since 2023, hands are still the area where they struggle most.

What to look for: Count the fingers. Check that joints bend naturally. Look at both hands — even if one looks correct, the other may have errors.

2. Text and Symbols

AI-generated images almost always get text wrong. Any text visible in the image — on signs, books, labels, or clothing — will typically be garbled, misspelled, or composed of letter-like shapes that don't form real words. This includes numbers, musical notation, and written scripts in any language.

What to look for: Zoom into any visible text. Real paintings either have legible text or deliberately abstracted text. AI art has text that tries to look real but isn't.

3. Unnaturally Perfect Skin

AI-generated portraits often have skin that looks too smooth, too even, and too perfect — almost like a beauty filter applied at maximum strength. Real paintings, even highly idealized ones, show the artist's technique: visible brushstrokes in oil paintings, paper texture in watercolors, or deliberate stylization in portraits.

What to look for: An uncanny smoothness, especially in portraits. Real painted skin shows the physical medium — canvas texture, brush marks, or pencil strokes.

4. Impossible Architecture and Perspective

AI often generates buildings, rooms, and architectural elements with subtly wrong perspective. Parallel lines that should converge don't. Stairs lead nowhere. Doors are slightly the wrong proportion. Windows don't align between floors. These errors are subtle enough to miss at first glance but obvious once you look carefully.

What to look for: Follow architectural lines to their vanishing points. Check that buildings have consistent structure. Look for stairs, windows, and doors that make physical sense.

5. Objects Merging Into Each Other

One of AI art's distinctive tells is the way objects sometimes bleed into their surroundings. A necklace might fuse with the neck. Hair might merge into a shoulder. A table edge might dissolve into a wall. Real paintings — even loosely painted ones — maintain clear object boundaries because the artist understands the 3D space they're depicting.

What to look for: Examine where objects meet. Jewelry, clothing edges, and accessories are especially prone to this artifact.

6. Inconsistent Style Within the Image

A real painting has a consistent technique throughout. The brushwork in the sky matches the brushwork in the foreground. AI-generated images can have patches that look photorealistic next to areas that look painterly, or sections with high detail adjacent to blurry, undefined areas — in ways that don't reflect deliberate artistic choices.

What to look for: Is the level of detail and rendering style consistent across the entire image? Real artists maintain stylistic coherence even when they vary technique between areas.

7. No Physical Original Exists

If an artwork only exists as a digital file and the seller can't show the physical original, that's a significant red flag. AI generates pixel images — it cannot create physical paintings on canvas. A real painting has a physical original with texture, thickness of paint, canvas weave, and aging that can be examined in person or in detailed photographs.

What to look for: Ask for close-up photographs showing paint texture, canvas grain, and the edges of the canvas. If the seller only provides the flat, front-facing digital image, be cautious.

8. No Provenance or Artist History

Real artworks have histories. They were created by artists who have biographies, exhibition records, and bodies of work. A painting attributed to a real artist should be traceable through their career. If an artwork appears with no artist information, no exhibition history, and no documented provenance, verify it before purchasing.

What to look for: Search for the artist's name online. Check if they have a gallery presence, exhibition history, or auction records. Use an art recognition app like ArtScan to check if the painting matches a known work.

How to Verify a Real Painting

If you want to confirm that a painting is a genuine work by a real artist, here are the most effective approaches:

• Use ArtScan — photograph the painting and the app will tell you if it matches a known artwork, who painted it, and its history
• Reverse image search — upload the image to Google Lens to find it in museum databases and art catalogs
• Check AI detection tools — services like Hive Moderation and Illuminarty can analyze images for AI generation artifacts
• Examine metadata — right-click the image file and check its properties. AI-generated images may have metadata from generation tools
• Consult an expert — for high-value purchases, a professional art appraiser can examine the physical work

The Bigger Picture

AI art generation technology is improving rapidly, and some of these visual tells may become less reliable over time. However, the fundamental difference remains: AI generates images from patterns in training data, while human artists create from intention, experience, and physical skill. The context around an artwork — its provenance, the artist's career, the physical original — will always matter more than any single visual test.

For art lovers and collectors, the best defense is knowledge: knowing what to look for, verifying claims, and using available tools to confirm authenticity.

FAQ

How can you tell if a painting is AI-generated?

Look for telltale signs: distorted hands and fingers, inconsistent text or symbols, unnaturally smooth skin textures, asymmetric facial features, impossible architectural perspective, objects that merge or bleed into each other, and an overall "too perfect" quality with no visible brushstrokes or canvas texture. AI art also lacks provenance — no artist history, exhibition records, or physical original.

Is there a tool that detects AI-generated art?

Several tools can help detect AI-generated images, including Hive Moderation, Illuminarty, and AI or Not. However, no tool is 100% accurate. For verifying real paintings and their artists, art recognition apps like ArtScan can confirm whether an artwork matches a known painting by a real artist in museum and gallery collections.

Can AI art be passed off as real paintings?

Digitally, AI-generated images can closely resemble photos of real paintings and have been used in online art fraud. However, AI cannot create physical paintings with real paint on canvas, so in-person verification remains reliable. For online purchases, always verify the artwork's provenance, request photos from multiple angles, and use art recognition tools to check if the work matches known originals.

Why does AI art struggle with hands?

AI image generators learn from patterns in training data. Hands are highly variable — they can have fingers in countless positions, overlapping, foreshortened, or partially hidden. This variability makes it harder for AI models to generate anatomically consistent hands, often producing too many or too few fingers, merged digits, or impossible joint angles.
