As we all know it Gemini is a brand-new large language model that is apparently going to rival existing ones. However, can AI detectors detect Gemini? The short answer is YES. The longer answer is the devil lies in the details. Keep reading to know more about it.
Why Gemini gets detected by AI detectors?
The simple answer is that none of these AI detectors are made specifically to identify Gemini alone—they just happen to detect many AI patterns. You will see this in the data below. All the major AI detectors—ZeroGPT, Winston AI, and Turnitin—are capable of catching Gemini because they are trained to spot text that has the stylometric or linguistic footprints of AI.
Which AI detector is best when looking for Gemini text?
There are many AI detectors out there, but let’s focus on these three heavy-hitters: ZeroGPT, Winston AI, and Turnitin. All those detectors were tested on 105 text samples produced by Gemini. The data from those tests is pretty revealing, so let’s have a closer look.
Here is the interactive HTML table that shows Gemini detection summary:
| Detector | n_texts | Mean_Score_% | Median | |
|---|---|---|---|---|
| 1 | ZeroGPT | 105 | 85.1 | 94.2 |
| 2 | Turnitin | 105 | 48.8 | 45.0 |
| 3 | Winston AI | 105 | 2.8 | 0.7 |
As you can see, ZeroGPT is showing pretty high mean and median scores, while Turnitin's numbers hover around 48.8 % mean, and Winston AI looks quite different because it shows a very low “human-ness” percentage. But the story doesn’t end with these raw numbers.
Key findings from the 105 Gemini‑generated samples
- Detection success (threshold ≥ 60 % AI probability)
• Winston AI: 99 % of the texts were flagged as AI.
• ZeroGPT: 88 % got flagged.
• Turnitin: 44 % were caught. - Raw confidence scores (mean ± median)
• ZeroGPT: 85.1 % mean, 94.2 % median. This implies consistently high AI-likelihood scores, meaning it sees Gemini text as “AI” most of the time.
• Turnitin: 48.8 % mean, 45.0 % median. You can basically call this an “unsure” area. It’s near the borderline, so many Gemini outputs might slip through.
• Winston AI: 2.8 % mean, 0.7 % median for human-likelihood. In other words, Winston AI’s engine believes 99% of Gemini text is definitely AI.
Why Winston AI’s detection is so high?
Winston AI is apparently made to be extremely sensitive towards AI text. Infact it flagged almost all the samples as AI. Although that might sound amazing for catching Gemini, it could lead to a lot of false positives. If your text is purely human written, you might still get flagged by Winston AI just because it is super aggressive.
ZeroGPT has a strong detection rate
ZeroGPT flagged around 88 % of the samples with high confidence. That is quite impressive, and the advantage is that its raw score is well above 60 % in most cases, so you won’t be left guessing if it’s AI or not. Also, if you’re worried about false positives for purely human writing, ZeroGPT might be less risky than Winston AI because Winston is being borderline overzealous.
Turnitin is not that reliable on Gemini
Turnitin’s scores are too close to the “unsure” zone. This means it might get half of the text right and half of it wrong. They do have a well-known brand name, but for Gemini generation, they don’t have strong detection coverage.
The Bottom Line
So, does that mean Turnitin is worthless when it comes to Gemini? Not necessarily. However, if you must vet Gemini‑generated content, ZeroGPT offers the best trade‑off between coverage and probably precision. Winston AI might catch all possible Gemini texts, but it can also produce many false alarms for real human works. Turnitin is ok but is definitely going to miss a lot of Gemini pieces.
Hence, my single opinion is—ZeroGPT is the go-to if you want a balanced approach to detecting Gemini. It’s not perfect, but it catches enough while still not going overboard like Winston AI.
