Undetectable AI’s Stealth Writer – Tested & Reviewed

The release and popularity of LLMs have set off an unfortunate chain of reaction — one that very few anticipated. With AI chatbots like ChatGPT becoming accessible to everyone, how can schools actually prevent AI misuse from happening in classrooms?

As it turns out, they can’t. At least, not reliably.

One of the bandaid solutions of this new era is the sudden rise of AI detectors. But slowly, people figured out that these platforms aren’t the solution — they’re actually part of the problem.

With false positives claiming the reputations of innocent students, how are we to cope with the variability that comes with AI detection?

The answer is simple: AI bypass tools. In this article, I’ll be reviewing Undetectable AI’s Stealth Writer and answer if it’s enough to prevent yourself from ever being falsely accused of using LLMs. Stay tuned!

What is Undetectable AI?

Undetectable AI is a paraphrasing tool that focuses on turning your input into something that hides from AI detection. This involves rewriting AI-generated (or something similar) text to remove signs that it was generated by an LLM and make it appear more natural. Here is our full review of the platform.

Undetectable AI’s pricing depends on volume and payment method. If you’re paying monthly, the price starts at $14.99 for 15,000 words and up to $209 for 380,000. If annually, the price begins at $60 (which rounds up to $5 monthly) for 10,000 humanized words and up to $1079 (equal to about $89.92 monthly) for 380,000. (Note: The price may have changed after this article is published.)

Is UD’s Stealth Writer Different From Its Paraphraser?

Short answer: Not really.

There’s no information online about what their differences are, but upon my own investigation, it seems that Stealth Writer is just a different term for Undetectable AI’s paraphrasing tool. It still has the same output customization features, namely:

• Balance: More readable, more human, and balanced.
• Purpose: General writing, essay, article, marketing material, story, cover letter, report, legal material, and business material.
• Readability: High school, university, doctorate, marketing, and journalism.

Not only that, but it also uses the same set of AI detection tools to check if their output has low AI likelihood scores. 

So, as far as I can tell, these are just the same tool, albeit with a different name.

The Output Quality of Undetectable AI’s Stealth Writer

Before we proceed with how well Stealth Writer hides from AI detection, we need to assess the readability of its outputs first. So, here’s an AI-generated text from ChatGPT, along with its equivalent using Undetectable AI.

A quick read will already tell you the biggest issue with using AI bypassers such as Undetectable AI. Yes, they’re incredibly effective at avoiding AI detection, but they’re also bad writers. Plain and simple.

The root of this issue stems from how Undetectable AI bypasses detection. It removes common AI words and adds a little more variety. But the largest aspect is that they add intentional errors to make it seem that the writing couldn’t come from an LLM since they only write flawlessly.

Undetectable AI’s essay has several readability issues that could be improved. The writing is choppy and lacks coherent flow, making it difficult for the reader to follow the main ideas. There are numerous grammatical errors, inconsistent punctuation, and awkward phrasing throughout the text.

The overall structure also needs work, as the ideas are not clearly organized or developed. Some sentences are run-on, which disrupts the reading experience. 

If you’re using this in an academic context, your teacher will be quick to note that — while the content of the essay may have merit — its poor structure and numerous errors lowers its readability. But don’t fret, instead follow these instructions on how to properly use Undetectable AI without sacrificing AI likelihood score.

The Final Tally

Wrapping Up

No matter what you call its paraphrasing tool, Undetectable AI remains the best AI bypasser in the market today.

But heed my warning: it’s not actually flawless — in fact, it’s so far from it. Removing AI detectors from the equation is just the start of truly creating human-like writing, but the second and most important part is actually applying it to your input while retaining its readability.

That doesn’t change the fact, however, that Undetectable AI is a good start. Just always remember to fix its output afterwards to prevent any further issues down the road.

Undetectable AI is an interesting topic, so we’ve written a lot about them in the past. Here’s one of my favorites. Enjoy!
