TurnItHuman vs. Undetectable AI: Finally, A Worthy Opponent

For years, I’ve sung praises of Undetectable AI. But there’s a new competitor that looks to be a serious contender: TurnItHuman.

You get an assignment, probably an essay, and you finish it on time. You submit it to your professor with pride. Suddenly, all your hard work is called into question because of an AI detection tool that flagged your paper as suspicious.

That’s not flash fiction – that’s a nightmare scenario playing out in classrooms across the world. Educators, eager to crack down on cheating, have turned to these AI detection tools. But here's the catch — these tools aren't nearly as accurate as they claim to be. In fact, they're generating tons of false positives.

To establish the status quo, students started using AI humanizers to make sure their hard work doesn’t go to waste. But the thing is, these platforms aren’t free and most students don’t have the money to spend on testing these tools. So, I’ve done the work for them.

In this article, I’ll compare TurnItHuman and Undetectable AI. Spoiler alert: one of these is the best in the market, and no, it’s not the one you probably expect.

What is TurnItHuman

TurnItHuman is an AI paraphrasing tool that can turn AI-generated content into something more human-like so that AI detection tools won’t flag them. The platform uses advanced machine learning to mimic the writing style of humans — saving you from false positive AI detection.

What is Undetectable AI

Long-time readers of ours would recognize Undetectable AI. This AI bypassing tool has been a mainstay at our website for a reason — it’s affordable, flexible, and most importantly, it works. Like TurnItHuman, Undetectable AI removes all traces of AI writing in your text, from common machine-generated words to monotonous and robotic writing. 

TurnItHuman vs. Undetectable AI: Readability

Since they’re both AI paraphrasing tools at their core, let’s start with readability. After all, it doesn’t really matter if your text passes AI detection, if they’re unreadable in the first place. So, let’s see how each humanizer performs when given text from ChatGPT:

Note: TurnItHuman has a great feature that I’ll discuss later, but for this round, I’m only going to use both humanizers’ standard paraphrasing.  

Original Essay

A tableau in art refers to a striking and static composition that evokes emotion, often resembling a living picture. Originating from theater, it involves performers posing motionlessly to convey a narrative or theme. In visual art, it mirrors this concept by freezing a moment in time, allowing viewers to reflect on its symbolism and meaning. Artists use tableaux to emphasize dramatic tension, highlight cultural themes, or immortalize fleeting beauty. For example, baroque painters like Caravaggio crafted vivid tableaux through dramatic lighting and composition. The tableau’s power lies in its ability to silently speak volumes about the human condition.

Tableau art is a special art style that has more impact than the normal art that are used for many different works. In current scenario tableau can do most of the work for example a good tableau can give high quality visual experience, with the help of different-different techniques artists can create various scenes like dramatic moments, cultural stories, and also make beautiful compositions of your favourite themes. These artistic scenes make your art very powerful by giving you different-different possibilities which help to complete your artistic expression. This art really caught the lime light during baroque period when artists like Caravaggio started using dramatic lighting for emotional impact.

TurnItHuman brings a more readable approach compared to Undetectable AI, which is frankly a disaster. TurnItHuman, while not perfect, maintains a basic structure that allows readers to follow the core ideas. It uses simpler sentences and attempts to communicate the concept with some coherence. The spelling is mostly accurate, though it does have some repetitive phrasing like "different-different" that breaks professional writing standards.

But Undetectable AI is practically incomprehensible. Its grammar is completely fractured, with random word placements, repeated words, and a structure that defies logical parsing. The spelling is erratic, and the text reads like a randomly generated sequence of words that only vaguely resemble a discussion about art. 

While TurnItHuman has some minor issues, Undetectable AI would require a complete rewrite to be considered readable. The lesson here? Don’t expect AI humanizers to be a substitute for careful, thoughtful writing.

Who wins? TurnItHuman, but only by default.

TurnItHuman vs. Undetectable AI: Output Customizability

Undetectable AI has the standard paraphrasing customizations, allowing you to get an output that’s more in line with your target readability or purpose.

TurnItHuman doesn’t have any of this, but what it does have, is just as promising. This is the only AI humanizer I’ve seen that lets you upload documents that you wrote, and the platform tweaks its output based on your writing voice.

Who wins? Each has a different approach on output customization, so it’s a tie for this round.

There’s no three words in the English language that I hate more than “I’m blown away” when describing products — but TurnItHuman has more than earned it. I was always under the impression that no AI humanizer can reach these numbers except Undetectable AI, but it seems that we’ve found a worthy opponent, and maybe, a better alternative. 

Speaking of Undetectable AI, this isn’t to say it’s still not good. 16.28% may seem high, but that’s only in comparison to TurnItHuman. Other times, I’d say this average is great, amazing even. There’s also the fact that Undetectable AI has proven itself time and again, so I’m having a hard time not recommending this product too. That said…

Who wins? TurnItHuman by a mile.

The Bottom Line

Every time we do one of these comparison articles against Undetectable AI, I’m waiting for something to compete. Many, many articles later, TurnItHuman is a viable competitor and could very likely be used alongside it.

This platform doesn’t only work, but it also promises exciting features like mimicking your writing voice. Their output is also very readable, which is significant!

So, TurnItHuman — definitely check them out, but remember: never, ever use AI humanizers to cheat. You’re not helping yourself if you use these products to cheat. Use them ethically and responsibly where it makes sense. Other than that, good luck!

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.
