Is this image AI? A visual checklist

Nine quick checks you can do by eye before you run a scan. The checklist does not give a verdict, because many AI images now pass every visual test.

0 of 9 checks done

This checklist is a thinking aid, not a detector. Modern generators often pass every visual check, so run the image through a scan as well.

What it shows

What you get

Fast first pass

Most obvious fakes fail one of these checks within a minute.

Teaches what to look for

Useful for classrooms, newsrooms and family conversations.

Pairs with a scan

Where the eye is unsure, a detector adds a second opinion.

Limits

  • Passing every check does not make an image real. Failing a check does not make it fake, since real photos have odd moments too.

How it works

  1. 01

    Zoom in

    Open the image at full size.

  2. 02

    Work down the list

    Tick each check as you do it.

  3. 03

    Run a scan

    Use Witness for a likelihood and a heatmap.

Frequently asked questions

Can I tell if an image is AI by looking?

Sometimes. Hands, text and background logic still trip up some generators, but the best ones pass casual inspection. A scan and a source check are more reliable together.

What is the fastest reliable check?

Find the earliest copy with reverse image search, then scan the image.
