The race between AI and the tools designed to detect it is never-ending. Just when you think you’ve found the AI detector, a new piece of tech comes along that’s designed to slip right past your defenses.
But what happens when you pit Undetectable AI against an up-and-coming AI detection tool? That’s exactly what I set out to discover by testing Isgen, a free platform that claims a staggering 96.4% accuracy rate in identifying AI-generated text across 80+ languages.
Could this little-known detector stand up to the might of Undetectable AI, or would it crumble under the pressure just like so many others?
What is Undetectable AI?
Most AI paraphrasers (at least, the ones that are most popular) make your writing better. Undetectable AI is the exception. This AI tool humanizes your input so that it can bypass common AI detection tools.
By inputting a piece of text into Undetectable AI and pressing “Humanize,” you can easily get a paraphrased version of your text that will be identified as human by most detectors. You can also change the readability, use case, and balance level of your output to match the intent of your original text.

What is Isgen?
AI detection tools are a dime a dozen nowadays, but Isgen promises to be the most precise free AI detector. It claims that it’s able to detect AI content written in 80+ different languages with an accuracy of 96.4%. But does that reflect reality?

The Final Tally + Thoughts

Isgen AI vs. Undetectable AI: |
|
You might see this score and assume that Isgen AI isn’t worth your time — I’d argue the opposite. Here’s why:
We’ve tested some of the most popular AI detection tools against Undetectable AI, and their average AI likelihood scores are:
I had low expectations of Isgen (especially since it’s less popular than its competitors) but they proved me wrong. At 34.92%, it’s the most correct AI detector (behind Winston, which mind you, is a paid service) against Undetectable AI, the most potent AI humanizer in 2024.
So, What Now?
At the end of the day, the battle between Isgen and Undetectable AI is a great example of how good technology will always be succeeded by a better one. Just when you think you’ve found the holy grail, along comes new tools or improvements to platforms like Undetectable AI that allows AI writing to slip right through the cracks.
But you know what they say — you can’t keep a good detector down. And Isgen has proven that it’s got the chops to hang with the big dogs, even if it’s not a household name… yet.
Of course, no detector is perfect, and I’m sure Undetectable AI will continue to innovate and find new ways to evade detection, especially since false positives are still a worry in AI detection. But for now, Isgen stands out as one of the most capable free AI detectors on the market.
If you’re looking for a tool to help you navigate the treacherous world of AI-generated content, I’d highly recommend giving Isgen a try. But if you’re looking for a solution against the threat of false positive AI detection, Undetectable AI is more than enough for your problems.
