Among all AI humanizers, Undetectable AI is the only one I know that continuously innovates and updates their platform. Apart from their AI-to-human paraphrasing tool, they already have an AI human typer and detection tool — but it seems that it wasn’t enough.
Late last year, they unveiled new features for translation, cover letters, SEO writing, essays, and more.

But one thing caught my attention: their AI chatbot.
With the promise of outputs that are already invisible to AI detectors, I was eager to try it. But to fully know how capable it truly is, I needed something to compare it with. So, this is Undetectable AI’s chatbot vs. Claude.
What is Claude?
Claude is Anthropic’s AI model that’s been making waves since its release — and for good reason. What sets Claude apart, according to them, is that it actually understands context, nuance, and (here’s the kicker) it can actually follow complex instructions without completely losing the plot halfway through.
Whether you’re brainstorming ideas, analyzing data, or just having a thoughtful conversation, Claude handles it all with a level of comprehension that feels surprisingly… human.

The Claude family has evolved quite a bit since its debut, and now includes some seriously capable models worth knowing about.
At the top sits Claude 3.7 Sonnet which brings serious reasoning power and can handle pretty much anything you throw at it. Then there’s Claude 3.5 Sonnet, slightly older but still packing impressive capabilities. Claude 3 Opus is supposedly Claude’s best writer and analyst, while Claude 3.5 Haiku is perfect for quick responses.
What is Undetectable AI?
Undetectable AI is an AI humanizer platform that’s made to circumvent AI detection models — and it works. It started out with just a simple paraphraser and detection model. But like Claude, it has since expanded their offerings to include AI specialized tools for writing cover letters, essays, and many more.

Today, we’re focusing on one of their newest features: an AI chatbot. Supposedly, the output of this model immediately bypasses AI detection — something that I want to confirm for myself.

So, What Now?
It’s important to make this distinction now: I am, in no way, insinuating that Undetectable AI is a better chatbot than Claude. In fact, I’d even go far as to say that Claude’s definitely the better of the two. Not only is it more nuanced, it’s just capable of so much more than Undetectable AI.
This comparison is just for bypassing AI detection, and in that regard, Undetectable AI is the clear cut winner.
That said, I want to commend Undetectable AI and Claude for championing honest AI use. Both of them are against using their own platforms to cheat your way to high grades. It’s refreshing to see tools that are vocal about ethical AI use in this climate.
So, with all that said, good luck on your work, and if you want to learn more about Undetectable AI, check this article out.
