I’ve been a long-time user of Undetectable AI, so imagine my surprise when, one day, I saw that they updated their website. I’m familiar with how great most of their tools are, especially their humanizer, and it was such a nice update to see them introduce new tools. But one thing really piqued my interest.
It seems that Undetectable AI has released a chatbot.
This is exciting for one reason: for people who’ve been using Undetectable AI with other LLMs, this means that they can just ask Undetectable AI directly to write them essays, stories, and cover letters. No need to switch tabs — it’s all just there.
And that got me thinking: can their output still bypass AI detection? And how does it compare against the best AI chatbots in the market? This is Undetectable AI’s chatbot vs. Google Gemini — let’s begin.
What is Gemini?
Gemini is Google’s entry in the AI arms race. Launched in December 2023 after years of development at Google DeepMind, it’s a multimodal AI system that can handle different types of information all at once. While ChatGPT and other models started with text and then bolted on image capabilities later, Gemini was designed from the beginning to work with text, images, audio, and video seamlessly.
Google released it in three sizes: Ultra (the big gun for complex tasks), Pro (the everyday workhorse), and Nano (the lightweight version that runs directly on mobile devices). This isn’t just about having different price points — each model serves different use cases depending on what you need.
What is Undetectable AI?
Undetectable AI is an AI humanizer that takes your AI-generated text (or something similar) and transforms it into something that flies under the radar of those pesky AI detectors. And it’s not just about dodging the algorithms — they’ve built in customization features so you can tweak the output to match exactly what you need, whether that’s readability level or how “human” you want it to sound.
But we’re not here to talk about Undetectable AI’s main feature. Instead, we’re going to test one of Undetectable AI’s new features against Gemini: their chatbot.
This is not your ordinary LLM: Undetectable AI’s chatbot immediately humanizes the output within their platform to make sure you’re bypassing AI detection.
Google Gemini vs. Undetectable AI
This isn’t a regular comparison of features as we’re only going to focus on bypassing AI detection. Let’s start.
Test #1
Undetectable AI: Successfully passes as human!
AI Likelihood Score: 0.3%

AI Likelihood Score: 100%
Test #6
Undetectable AI: Successfully passes as human!
AI Likelihood Score: 0%
Gemini: Text detected as AI-generated.
AI Likelihood Score: 100%
Overall Score
The Bottom Line
It’s no surprise that Gemini consistently got 100% AI likelihood score in this test — most AI detectors are likely trained using their output.
Instead, the real story here is Undetectable AI. I’ve always known that their humanizer was effective, but their chatbot gives the users the option to forgo using LLMs and head straight to the platform for help in writing essays.
But that doesn’t take away the fact that Gemini is just a great LLM and deserves its place along with ChatGPT, DeepSeek, and Claude. Undetectable AI is just (really) good at one thing — but Gemini is great at them all. There’s really no losers here, they’re both incredibly effective at what they do. In fact, you can even use them both for better results. Have fun trying them out!
