Convertavo AI Art Detector: Is This Art Made by AI?
Found a drawing online and something about it feels off? Convertavo's free AI art detector checks whether a drawing, painting or illustration came out of an AI image generator. You don't just get a score, you see the evidence. Upload a JPG, PNG or WebP, and the answer usually takes 2 to 4 seconds.
What the detector checks
An honest estimate, not proof. We tested the model on a labelled set of images, and it got about three in four right. So you'll always see how sure it is and what it found, and when it can't tell, it says so.
Your files stay private
Uploads are deleted from our servers one hour after processing. Nothing is read or reused, and nothing is kept unless you save it to your account.
No account required
20 free credits a day, with no email address and no watermarks on the output.
Runs on any device
Works in any modern browser on Windows, macOS, Linux, Android and iOS.
How to check if art is AI-generated
Three steps, nothing to install, no account needed.
- STEP 01
Add the artwork
Drop in a JPG, PNG or WebP up to 8 MB, or paste a link or the image itself. Bigger is better here, so use the largest copy you've got.
- STEP 02
Run the two checks
Click Check artwork. One check studies the texture and detail, and the other digs through the file for generator labels, prompts and Content Credentials.
- STEP 03
Weigh the evidence
You'll see a verdict, how sure it is, and every clue it found. Before you decide anything, ask about the artist's process.
A score is only half the story. Further down, we explain how to check the artist's process too.
What the AI Art Detector does
Kinder to real artists
We compared two models. The one we kept wrongly flagged far fewer human drawings than the other.
Shows how sure it is
Art is tricky to judge. Every result tells you its confidence, and says "can't tell" when that's the truth.
Your art stays yours
It's checked on our own server. Nobody trains on it, and it's gone an hour later.
What does the AI art checker look at?
Every picture goes through two checks. The first looks at the image. The second looks at the file it came in.
Check 1: the pixels
An open-source AI model, called a classifier, looks closely at texture and detail, the stuff your eye skims past. It still works when someone has wiped the file's hidden data.
Check 2: the file itself
Most image files carry hidden notes called metadata. The detector reads them and looks for:
- the program that last saved it, such as Photoshop, GIMP or Affinity
- a full prompt and settings, which Stable Diffusion apps like to tuck inside the image
- labels left behind by Midjourney, DALL-E, Firefly, Stable Diffusion and others
- Content Credentials, a signed label that Adobe Firefly and some other tools attach to say AI was involved
- camera details such as lens and exposure, if someone photographed a real painting
Don't read too much into a missing label, though. Exporting, screenshotting or posting to social media strips this data from real art and AI art alike.
How accurate is an AI art detector?
It's an educated guess, not proof. We tested it on a labelled set of 24 images, and it got about three out of four right.
So you'll always see how sure it is. And if it honestly can't decide, the report just says that.
Why is AI art harder to spot than AI photos?
A real photo is full of little flaws: grain from the camera, a bit of blur from the lens, light bouncing off the walls. A fake AI "photo" sticks out against all of that.
Art doesn't have any of it. Digital paintings are smooth because the artist wanted them smooth. 3D renders come out spotless. A vector drawing has no grain at all.
So to a model, plenty of human art already looks a little odd, and there are fewer clues left to tell it apart from AI art.
Which art styles are hardest to check?
Some styles are just harder to call than others. Here's roughly what to expect.
| Art style | What to expect |
|---|---|
| Anime, manga, concept art, fantasy portraits | The toughest group. AI has copied these looks so much that the result can swing either way. |
| Smooth digital painting, 3D renders | Expect the odd false alarm. Honest work in these styles sometimes gets marked as AI. |
| Pencil sketches, ink drawings, a painted canvas photographed with a camera | Much easier. You can see the paper texture and the camera's own noise, and AI is bad at faking both. |
How to tell if art is AI-generated by looking at it
Get up close and go slowly. A single weird detail could be anything. But if you keep finding them, that tells you something.
Start with the detail. A real artist saves the effort for the face, or whatever the picture is about. AI tends to polish everything the same, right down to the buttons on a coat in the background. So detail everywhere is the first thing to notice.
Then look for patterns that almost repeat. A lace border or a row of tiles drifts a little as it goes along. Earrings that are meant to be a pair come out as two different shapes.
Check anywhere two things touch. Things melt together in AI art: fingers merge, a guitar neck bends, a chair leg stops halfway down.
Fake writing is another giveaway. From a distance there's a signature in the corner. Up close, it's a scribble that isn't any real word.
Scroll through the whole portfolio, too. A mix of famous styles, with brushwork that changes from piece to piece, should make you wonder.
Last, ask what's missing. No process at all, no sketches, no drafts, nothing half-finished, is often the biggest clue.
Why was my hand-drawn art flagged as AI?
It happens, and it's more likely with certain kinds of work:
- smooth digital painting, or lots of blending brushes
- 3D renders, which are clean and polished by design, much like AI output
- photobashing, where a picture is built from bits of photos
- art that went through an upscaler app, or got filters and effects piled on
How can I prove my art is not AI?
Show how you made it. Your process settles the argument better than any score, and any one of these will do:
- the layered file from Photoshop, Procreate, Clip Studio or Krita
- a time-lapse of you drawing it
- a folder of rough sketches and early drafts of the same piece
It's the reason so many artists now hit record before they start drawing.
Checking art for commissions, contests and shops
Paying for a commission, judging a contest, or buying prints? The strongest evidence you'll get is the artist's process, not a detector score.
Working artists can nearly always pull up a layered file, a time-lapse, some sketches or older drafts. Asking to see one is fair, and most won't mind.
Use the checker to work out which pieces to ask about first. A confident AI result with generator labels in the file is a good reason to ask. A shaky result on a stylised piece isn't.
Is Convertavo's AI art detector free and private?
Is it free?
Yes. You get 20 free credits a day, and each check uses 10, so that's two free checks every day. No email, no signup. Need more? A free account gives you 50 credits a day (five checks), and Standard plans and above add priority processing.
What happens to my art?
We check it on our own server. Your image never goes to an AI company, and we don't train anything on it.
An hour after the check, it's deleted from our servers. Nothing is kept, read or reused.
Does it work on my phone?
Yes. It runs in any modern browser on Windows, macOS, Linux, Android and iOS, so there's nothing to install.
Checking a photo instead of a drawing?
For photos, head to our AI Image Detector. It runs the same two checks, but that page walks you through the clues photos leave behind, like camera data and lens details. This page is all about drawings, paintings and illustrations.
Either way, the model behind it was picked for one reason: in our tests, it mistook human art for AI far less often than the other one we tried.

Check artworkCommon questions about checking AI art
These come up a lot from artists, buyers and contest judges.
Can this tell if art is AI-generated?
Sometimes. In our own test it was right 18 times out of 24, which is decent but nowhere near perfect. We'd ask the artist for a layered file or a time-lapse before deciding anything based on it.
How can I prove my art is not AI?
Record a time-lapse while you draw. Procreate and Clip Studio can both do this. No recording? A layered PSD or .procreate file does the job, and even a phone photo of the first sketch helps.
Why was my hand-drawn art flagged as AI?
We picked this model because the other one we tried called every single human illustration AI. This one got 7 of 8 right. What still trips it up is very smooth painting, upscaling and heavy filters. 3D renders and photobashing can set it off too.
Can it detect Midjourney or Stable Diffusion art?
Yes, as long as the file still has its label. We check PNGs for the prompt that Stable Diffusion apps save, and look for the tags Midjourney, DALL-E and Firefly add. Screenshots and social media uploads remove these, and then only the pixel check is left.
Is the AI art detector free?
Yes. You get 20 free credits a day and a check uses 10. You don't need an email or an account.
What is the difference from the AI Image Detector?
Under the hood it's the same detector. This page is written for drawings, paintings and illustrations, and the AI Image Detector page is written for photos.
