AI is taking over the world, or so it seems. Industries are scrambling to adapt, and everyone's trying to figure out how this change in the status quo plays out. For students and writers, the initial enthusiasm surrounding AI tools has been tempered by the popularity of AI detection tools, particularly by their tendency to create false positives.

That's why it's important to equip ourselves with tools that can avoid false positives and its consequences. With Undetectable AI, you don't have to worry about being accused of using ChatGPT or other AI tools anymore. Or, so they claim.

Well, that's what we're going to find out today. In this article, I'll test Undetectable AI against 8 different detectors to find out, once and for all, if its actually effective or just another dud. So, let's dive in.

Our Test Cases

The first thing we need are some AI-generated writing samples and their Undetectable AI equivalents. For this batch of tests, I'll be using ChatGPT to generate the original texts. There will be three test cases: one for essays, one for stories, and another one for cover letters. Here's what I have so far, along with what they look like after running them through Undetectable AI:

Once upon a sunny hill, I'm a little cherry tree named Cherry Belle. My leaves wiggle when the wind tickles them, and I wear a crown of pink blossoms that dance in the spring breeze. Every morning, I stretch my branches like I'm doing a happy dance, reaching for the sun's warm hugs. Birds, like feathered friends, visit me, singing sweet songs and playing hide-and-seek in my branches. In summer, my cherries blush like rosy cheeks, inviting friends to pick and share. When autumn comes, my leaves put on a fiery fashion show before fluttering down like confetti. And when winter wraps me in a snowy blanket, I dream sweet dreams of sunny days to come. Oh, the joy of being a cherry tree!

Each morning I extend my branches as if dancing happily reaching out for the suns embrace. Birds like companions come to me chirping tunes and playing games within my branches. In the summertime my cherries turn red like blushing cheeks welcoming visitors to pluck and enjoy them together. As autumn arrives my leaves showcase a display before falling down like confetti. Wrapped in a blanket during winter I drift into dreams of sunny days ahead. The happiness of being a cherry tree is truly special!

All Said And Done

After testing Undetectable AI against specific detectors before, I expected it to perform well, but not this well. With a score of 6/8 detectors passed, it's genuinely amazing how good it is now with bypassing detectors.

As for the detector side, it makes sense that Winston's the only AI detector to figure out that these are AI-generated. We recently did an AI vs. detector article, and even then, Winston was the only one reliable enough to figure out that Undetectable's outputs were AI-generated consistently.

That said, always remember that you also have to tweak Undetectable AI's output after generating them because they use intentional machine errors as a substitute for human errors. Also, never use Undetectable AI for academic dishonesty.

Hi, I'm Angelo. I'm currently an undergraduate student studying Software Engineering. Now, you might be wondering, what is a computer science student doing writing for Gold Penguin? I took up studying computer science because it was practical and because I was good at it. But, if I had the chance, I'd be writing for a career. Building worlds and adjectivizing nouns for no other reason other than they sound good. And that's why I'm here.
