As we all know it ZeroGPT is one of those AI detectors that claims to detect everything, from ChatGPT to Grok, so you might be wondering whether it can detect text generated by Google’s Gemini Advanced. The short answer is YES. The longer answer is that it’s complicated and depends on a lot of factors, such as whether you are just copy-pasting Gemini’s output as is or if you’re making small edits. Keep reading to learn more about it.
Why Gemini Advanced might get detected by ZeroGPT?
The simple answer is that Gemini Advanced is not made primarily to bypass AI detectors. If you go by Google’s marketing of Gemini, they never mention anything about escaping AI detection. Hence, if it is not made to accomplish that specific task then it typically won’t be effective at it.
Gemini Advanced is part of Google’s Workspace Enterprise or Google One AI Premium plan. It has a large context window (up to 1,000,000 tokens), advanced reasoning, and it can generate images and even short videos. But none of that necessarily helps you in bypassing an AI detector. Most AI detectors like ZeroGPT look at perplexity or so-called “burstiness” in your text. Unfortunately, Gemini’s advanced writing style can sometimes produce uniform, consistent text that can be low in perplexity in certain parts. That’s enough to get flagged by ZeroGPT.
My personal experience
I tested 10 samples written by Gemini 2.5 Pro (from Gemini Advanced) on ZeroGPT. The results were not so good if your main goal is to bypass detection. Out of these 10 samples, only 1 sample displayed below 10% AI probability. This was the one where I used a bunch of different humanizer prompts. Now, I know that 10 samples are not a super large dataset, so obviously it is not a 100% proof. But I can see that ZeroGPT has updated their model because they claim on their homepage that they can detect Google Gemini. Once they update their models (classifiers), it becomes trivial for them to detect raw outputs from Gemini.
Which tool is specifically made to do the bypass job?
There are lots of “AI humanizer” tools out there that advertise themselves as specialized in passing AI detectors. For example Deceptioner etc. They are designed in such a way that they focus on increasing text perplexity, adding small grammatical inconsistencies, and using synonyms or partial rewriting that might fool detectors like ZeroGPT.
ZeroGPT, on the other hand, focuses on analyzing the uniformity and predictability of your text. If you simply paste raw Gemini 2.5 Pro output, there’s a good chance ZeroGPT will see enough patterns to label it as AI. However, if your text has lots of surprising word choices, plus varied sentence lengths, you might slip by.
Why is ZeroGPT able to detect Gemini Advanced?
ZeroGPT uses a combination of perplexity-based analysis, burstiness checks, and a large neural network classifier that they call DeepAnalyse™. Gemini might be super powerful for generating text and images, but it’s not specifically designed to evade these detection techniques. So it is likely that ZeroGPT is going to flag a straightforward Gemini output majority of the time.
Also, LLMs have a tendency to produce near-perfect English with minimal grammar and spelling mistakes. Some people have observed that if you want to fool these detectors, you might want to introduce random, subtle errors. Or you can break the text into short sentences, or use random punctuation patterns. Tools like Gemini typically produce coherent, well-structured text, which ironically is easier for ZeroGPT to detect.
Frequently Asked Questions
Q1. Does ZeroGPT detect Gemini Advanced’s output easily?
Yes, it generally does. Gemini Advanced doesn’t claim to be an undetectable paraphraser. If you just copy-paste text from Gemini, ZeroGPT can likely flag it.
Q2. Is Gemini Advanced free?
Gemini Advanced is not free for permanent usage. You can get a free trial with certain programs (like Pixel 9 Pro) but after that, you need a subscription via Google One AI Premium or a Google Workspace Enterprise package.
Q3. Is using Gemini Advanced plagiarism?
Not at all, as it is an AI model generating original text (assuming you’re not copying someone else). But it can still get flagged by ZeroGPT or other detectors as “AI-generated”.
Q4. Is ZeroGPT accurate?
They claim 98% accuracy, but independent tests put it closer to 70-75%. There are also many false-positives. Still, it’s one of the more known AI detectors around.
Q5. Which rewriter or humanizer can bypass ZeroGPT effectively?
Tools like Deceptioner, Undetectable.ai, or Stealthwriter.ai are purpose-built to do this kind of stuff. They tweak text in a way that is less likely to be flagged. You can also try manual editing if you have the time.
The Bottom Line
ZeroGPT can detect Gemini Advanced text pretty easily if you just paste it as-is. But if you want to bypass detection, you need an AI text humanizer or do manual edits. My personal tests show it might occasionally slip through with certain rephrasing but it’s not consistent. If passing AI detectors is your top concern, it’s better either to write everything on your own or use dedicated paraphrasers to do it.
