ZeroGPT Reviews 102

ZeroGPT actually works! It reliably spots AI-generated text without the false alarms you get from other detectors. Highly recommend!

I wrote an essay by myself, but because my teacher is really strict on AI I always put it through a detector anyways just to be sure. when I put it through this one it said it was 100% AI. I put the same essay through 3 other Ai detectors I use, all of them said 0% AI. I changed my essay so it had one noticeable phrasing problem in a sentence and put it through this detector again, and it then said it was 27% AI instead of 100%. this thing is fully just pulling numbers out of thin air. worst detector I've ever used.

Very inaccurate. I types in a passage from a 19th century book and it flagged 30% of it as AI generated! Don't use this piece of garbage,

I understand if some companies want to promote their paid services, but wasn’t expecting something so ridiculous.

I pasted a document to check if my text sounded “human”, as I had to include some scientific definitions and classifications in the text.
The Result:
My entire own entry was highlighted as AI-generated! The ridiculous part was that the scientific definitions I I had copied-pasted, were highlighted as “human”.

This service is a joke!

Good quality of service and decent work in online business, it is acceptable to work here, I use it constantly.

Everything I posted was AI based on it's checker and the subscription is a scam that need you to pay more money after you sub to check more words.

Absolute trash. I wrote an academic text by myself and it keeps giving me 100% AI generated, which it is not.

Not accurate at all

Incredibly inaccurate, flags almost everything above 50% AI, even when the text is human-written.

Its very very very unreliable, I wrote down my texts but it says 100% , I guess my brain works like a genius :)

The service is highly inaccurate about the ai percentage in the text, especially in academic-style writing. The website constantly tells me that my own text, which i've written with my own hands is likely to be ai, when in fact, it is not

I wrote so many random things and 8 times out of 10 the result was the same... 100% ai generated. Don't pay anything to this garbage detector

It appears to be a scam aimed at selling their "humanize" service.

gave the Declaration of Independence a 90% AI rating

Highly, highly inaccurate tool that gives far too many false positives and may unfortunately make life more difficult for students and writers who are actually doing their own writing. How do I know? I am a professional writer who still writes everything by hand. But I check my work against these so-called AI checkers because I know that editors out there are probably using them. Even if I write every single word myself, ZeroGPT will still say something ridiculous like 20% AI when the far superior, actually useful GPTZero (a different tool with an unfortunately similar name) will say 0% AI and 100% human. Remember: use GPTZero, not ZeroGPT.

Calling their AI checker garbage would be a disservice to actual garbage.
Apparently, whatever they fed their checker during training consisted either of Reddit posts or 3rd grade-level writing, because in their opinion, human beings can't have a decent vocabulary that includes multi-syllable words and compound adjectives. Or, God forbid, humans actually write detailed descriptions. How dare they, right? No human possesses imagination. Sure, only AI is capable of that.
They flaunt their services as "trusted" on their website and promise a 98% accuracy of the tool with a 2% error margin. That's the biggest BS ever. I've done so many experiments to see what triggers it, what specific words or sentence structures make it have this knee-jerk reaction, and came to a simple conclusion: it's dumb, and you need to write dumb for the AI detector to believe you're human.
It's upsetting that they don't have those nice review forms on their website, but also smart, because they'd end up inundated with outraged comments. The worst thing? It pops up first if you Google search for a detector.
Please, just don't use it. It's trash. Pure trash. I seldom write reviews, especially if they are scathing, but I'd give this zero stars if I could.

Biggest AI slop of them all

Lets say you have an essay due tonight, no problem right? so youre doing some finishing touches and decide to go check how AI it looks, so you cant get a fail because of that.
Worst mistake of your life!
No matter what you do it will never be 0%, thats unless of course you get the closest 4 year old who doesnt know what a comma is to write it.
i spent 30 MINUTES to try to get it to less than 20% but oh it just kept going up and up and up! eventually i give up and go check the humanizer thats linked on the site to see how im (APPARENTLY) supposed to write it.
LETS JUST SAAY that 4 year old couldve written it 5x better. It removes every comma in sight, because obviously nobody real uses those anymore right? It also gives EVERY SINGLE TINY THING AND DETAIL their very own SENTENCE. Oh and of course it came as 0%, like thats how humans write right?
anyway i knew better than to submit that slop and just used what i had.

DO NOT USE IT unless youre teaching second graders of course then its probably fine.

Anybody who knows how to write like a normal person will never get a zero on it though!

would give 0 stars if possible
thank you, bye!
(I have 5 minutes to finish it now but this rant was 100% worth it)

This is one of the most useless AI detectors. Shame on whoever is behind it. SHAME!! Your faulty tool is making life a nightmare for students and freaking professional writers! Pull it down or improve!!

My wife subscribed to ZeroGPT in July 2025, intending to buy a one-month plan to check a single document. Instead, I was charged for a full annual plan without receiving any confirmation email or invoice. I only discovered the charge later when checking my bank account.

She immediately contacted support, but they refused a refund citing a 7-hour refund window, which is unreasonable — especially since no confirmation was provided. After one reply, they stopped answering my emails altogether.

I have never seen a subscription service with such an unfair policy, and the lack of transparency plus poor customer support makes this company highly questionable. Be very careful before providing your payment details.

I’ve tried several AI detectors, and most of them give false positives and are unreliable. ZeroGPT, however, is much more accurate. It correctly identifies AI-generated text and human-written text with far fewer mistakes. I really appreciate how reliable it is, and I would recommend it over other AI detection tools. This is the only one I’ve found that actually works well.
