AI-generated pictures have exploded in recognition during the last couple of years. Instruments like Midjourney and GPT are actually creating visuals that blur the road between actual and artificial. As this type of content material turns into extra frequent, it’s no shock that folks desire a solution to confirm what’s made by a machine.
That’s the place AI picture detectors are available — and on this article, we’re evaluating two of them: Undetectable AI’s picture detector and AI or Not. Each instruments declare they will reliably spot AI-generated pictures. We needed to see how they deal with pictures from some of the superior mills on the market: Midjourney.
We ran 10 Midjourney-generated pictures by way of each detectors and recorded their responses. Some outcomes had been spot-on. Others had been off. However general? Let’s simply say it made issues attention-grabbing.
What’s Undetectable AI
Undetectable AI initially launched as a instrument to humanize AI-written content material, serving to it cross by way of detectors like GPTZero and Turnitin. But it surely’s not too long ago expanded into new territory: picture detection.

The picture detector works equally to their AI detection instrument. You add a picture, and it scans for digital fingerprints that recommend it was generated by AI. These embrace issues like texture uniformity, edge smoothness, and visible anomalies: components most people wouldn’t discover, however a skilled mannequin would.
In contrast to another instruments, Undetectable AI additionally offers you a confidence rating—telling you not simply if a picture was doubtless AI-generated, however how doubtless.
What’s AI or Not
AI or Not is a standalone picture detection platform constructed particularly for figuring out AI-generated visuals. It’s broadly utilized by educators, journalists, and fact-checkers, and is thought for its simplicity: simply add a picture, and it offers you a binary end result—”AI” or “Human.”

The catch? Further options are locked behind a paywall.
Undetectable AI vs. AI or Not: Midjourney Battle
We examined 10 pictures generated by Midjourney, all with sensible aesthetics — starting from stylized portraits to detailed scenes. Every picture was run by way of each Undetectable AI and AI or Not. Right here’s how every instrument carried out:
Check #1
Undetectable AI: Accurately recognized Midjourney picture as machine-generated.

AI Or Not: Accurately recognized Midjourney picture as machine-generated.

Check #2
Undetectable AI: Accurately recognized Midjourney picture as machine-generated.

AI Or Not: Accurately recognized Midjourney picture as machine-generated.

Check #3
Undetectable AI: Accurately recognized Midjourney picture as machine-generated.

AI Or Not: Accurately recognized Midjourney picture as machine-generated.

Check #4
Undetectable AI: Accurately recognized Midjourney picture as machine-generated.

AI Or Not: Accurately recognized Midjourney picture as machine-generated.

Check #5
Undetectable AI: Accurately recognized Midjourney picture as machine-generated.

AI Or Not: Accurately recognized Midjourney picture as machine-generated.

Check #6
Undetectable AI: Accurately recognized Midjourney picture as machine-generated.

AI Or Not: Accurately recognized Midjourney picture as machine-generated.

Check #7
Undetectable AI: Incorrectly recognized Midjourney picture as human.

AI Or Not: Accurately recognized Midjourney picture as machine-generated.

Check #8
Undetectable AI: Accurately recognized Midjourney picture as machine-generated.

AI Or Not: Accurately recognized Midjourney picture as machine-generated.

Check #9
Undetectable AI: Accurately recognized Midjourney picture as machine-generated.

AI Or Not: Accurately recognized Midjourney picture as machine-generated.

Check #10
Undetectable AI: Accurately recognized Midjourney picture as machine-generated.

AI or Not: Incorrectly recognized Midjourney picture as human.

Common Rating
Each instruments ended up with an identical scores—however they didn’t miss the identical pictures. Their strengths confirmed up somewhere else, which made this much less about who “received” and extra about how they differ.
The Backside Line
In the event you’re attempting to detect AI pictures—particularly from Midjourney—each of those instruments are viable. They’re not good, however they’re getting shut.
Undetectable AI is best if you would like extra detailed suggestions free of charge and confidence scores. That’s helpful if you’re coping with higher-stakes content material or visuals that look borderline actual. AI or Not is best if you desire a fast yes-or-no reply with out overthinking it.
However right here’s what stood out essentially the most: each instruments scored a 90% accuracy price. Which is nice for AI detection as a complete.
Are each instruments actually that evenly matched? Or did we simply occur to select a batch of pictures that performed to their strengths? Possibly. However both means, each instruments delivered.
As AI visuals hold evolving, you may wager these detectors might want to sustain. We’ll be watching.
