Every time I review another AI detection tool, I die a little inside.
Don’t get me wrong — I love putting these platforms through their paces. But after testing dozens of them, you start to see a pattern: big promises, flashy marketing, and (more often than not) disappointing results. Oftentimes, they fail to detect content directly from ChatGPT or Claude — much less AI humanizers.
Today, we’re looking at two players in the world of AI text: Undetectable AI, a popular AI bypassing tool, and Quetext, supposedly an accurate AI detector. One tries to hide AI writing, the other tries to find it — but does either actually work?
What is Undetectable AI?
Undetectable AI is an AI paraphrasing tool that’s focused solely on rewriting your content so that it avoids being flagged by AI detectors. This is done by changing specific parts of your text so that it appears more human-like.
What I like about Undetectable AI is that they also ensure that their output matches the readability and purpose of your input by adjusting their paraphraser according to different parameters.
- Use Case: General Writing, Essay, Article, Business Material, Marketing Material, Legal Material, Story, Cover Letter, Report
- Readability: High School, University, Doctorate, Journalist, Marketing
- Level: Balanced, More Human, More Readable

How Does Undetectable AI Work?
The one thing that Undetectable AI does really well is humanizing AI content, but the thing it does really poorly is (ironically) paraphrasing. Let me explain by showing you two essays:
|
Knighthood was a noble calling that exemplified the warrior ideals of feudal society. Pledging unwavering allegiance to their liege lords, knights upheld the values of chivalry, courage, and honor on the battlefield. Rigorous training from youth forged their martial prowess with sword and lance. Yet, knighthood transcended mere martial skill—it embodied a code of ethics. Knights vowed to defend the weak, remain loyal, and uphold virtue. As mounted elite soldiers, they were crucial to medieval military forces. However, the true essence of knighthood resided in its romantic chivalric traditions which celebrated the knightly virtues of piety, courtly love, and service. This sacred fraternity left an indelible mark on history. |
The title of being a knight was seen as a duty that represented the warrior values of the society. By promising their loyalty, to their lords knights upheld the principles of chivalry, bravery and integrity during battles. Through training starting from an age they honed their skills in combat using swords and lances. However knighthood was more than about fighting—it embodied a set of standards. Knights pledged to protect the vulnerable stay uphold goodness. As soldiers on horseback they played a role in medieval armies. Yet the true essence of knighthood lay in its traditions that glorified virtues like devotion to God, love and service to others. This revered brotherhood made a lasting impact, on history. |
If I’m being honest, the difference between these two essays is night and day. The first one, straight from ChatGPT, reads like something you’d find in a history textbook — clean and polished, but predictable. It’s got that AI “perfectness” to it that just screams machine-generated content. You know what I mean?
The sentence structure is varied but follows a pattern, and every word feels carefully chosen.
Now, the second essay? It’s like someone took that first essay and made it sound more… human. There are these little quirks – like breaking up sentences with commas in slightly odd places and simplifying some of the vocabulary. “Unwavering allegiance” becomes just “loyalty,” and “exemplified” turns into the more casual “represented.”
It’s not necessarily worse, just messier in that way human writing tends to be, but dialed up to a ten. What’s interesting is that while both essays say basically the same thing, the second one feels more like something a student might actually write – complete with those small imperfections that AI detectors usually look for.
What is Quetext?
So, let’s talk about Quetext. It’s another player in the growing (honestly, there’s a new AI tool every minute) field of AI detection and plagiarism checking tools. But does it live up to its promises? Well, that’s what we’re here to find out.
Quetext claims to be the best at detecting both plagiarism and AI-generated content. They’ve got this fancy “DeepSearch Technology” and something called “LightSpeed recognition.” Sounds impressive, right? But we’ve heard big claims before, so let’s not get too excited just yet.
Now, I could dive into all the features Quetext offers, but that’s not why we’re here today. Nope, we’re zeroing in on one thing and one thing only: their AI detector.
Quetext’s AI Detection Tool
Quetext says that their detector is “highly accurate in testing.” It works similar to most detectors today: input text and wait for an AI likelihood score. No frills, but what matters most is if they’re accurate — so, is it?

Quetext vs. Undetectable AI |
|
Look, testing any AI detection tool against Undetectable AI is a recipe for disaster — and Quetext is no exception. It’s proven time and again that it’s the best bypasser in the market. But still, 20% is pretty admirable considering how good Undetectable AI is. The only problem is that it isn’t free, and there are paid detectors that do a way better job (like Winston).
So, What Now?
After all these tests, one thing’s crystal clear — we’re in the middle of an AI arms race, and nobody’s winning.
Undetectable AI is living up to its name, even if its paraphrasing can sometimes make teachers cry. Quetext is trying, bless its heart, but catching 1 out of 8 AI texts isn’t exactly revolutionary when you’re paying for the service.
But here’s what keeps me up at night: what happens next? As these tools get better, how do we balance innovation with integrity? I don’t have all the answers, but I do know this — whether you’re using AI to write or trying to detect it, we need to think about the bigger picture.
For now, if you need recommendations: Undetectable AI for bypassing, absolutely any other paid AI detection tool for checking, and maybe save Quetext for… well, I’ll get back to you on that one.Want to explore more options?
