Ever had the urge to utilize AI for writing, but concerned about potential detection? With the rise of AI, numerous tools have emerged to keep up with the constant flow of content. If you enjoy writing but find yourself needing to produce repetitive text, you may be considering AI writers. However, the worry of detection remains.

Enter StealthGPT, the solution. It’s an AI writing tool that aims to create content that is both human-like and original, evading popular AI detectors like GPTZero and Turnitin. Curious to know more? Check out this StealthGPT review.

Get Undetectable AI Writing with AIHumanizer

Elevate your digital prose to new levels of sophistication and effortlessly evade AI detection by utilizing AIHumanizer as your secret ally.

What Sets StealthGPT Apart?

StealthGPT is an AI-powered tool that aims to produce undetectable AI content, whether by humanizing existing text or generating new. It understands the triggers that AI detectors look for and avoids them, making your content appear as if it were written by a human. It can infuse uniqueness into your emails, blog posts, and more, without resorting to common, mundane AI clichés.

Key Features of StealthGPT

Let’s delve into what StealthGPT has to offer.

Bypass AI Detector

Based on its description, StealthGPT has the ability to bypass even the most stringent AI detectors and generates content that is always unique, thus avoiding plagiarism. Notably, well-known AI detection solutions such as Originality.AI, Winston AI, GPTZero, and Turnirin have all failed to detect the content produced by StealthGPT.

Stealth Tools

StealthGPT provides a range of stealthy tools and offers customization options, utilizing engines like the exclusive Stealth Samurai Engine.

In addition to the Stealth Bypass tool, which humanizes text, StealthGPT also includes the Stealth Content Generator and Stealth Essay Generator tools for more specific purposes. This means that you can generate original content and even have the tool write essays based on a few prompts.

API

Furthermore, users have the ability to build their own stealthy applications by integrating StealthGPT’s API into their projects. If you are a developer who needs to handle automatic content processing, this feature might be of interest to you. The API’s pricing is based on a token-based fixed price model.

Pricing

StealthGPT offers three pricing plans: Essential for $14.99 per month, Pro for $19.99 per month, and Exclusive for $29.99 per month. Each plan has different word limits and bonus features. Additionally, you have the option to upgrade any plan to the advanced Stealth Samurai engine for an additional $4.99, regardless of the tier.

Effectiveness of StealthGPT in Making AI Content Undetectable: Real-Life Testing

While StealthGPT may sound impressive in theory, real-life examples and tests are the most valuable. Therefore, it is time to put StealthGPT to the test and determine if it can truly make AI-written text undetectable. You can easily access the test results by clicking here.

Firstly, in order to demonstrate its capabilities, the tool requires a text snippet generated using generative AI, such as ChatGPT.

This brief text, although concise, typically fails to deceive any AI detectors. The subsequent step involves processing this text through StealthGPT to ensure that ChatGPT remains undetectable.

Upon reviewing the resulting content, we discovered that StealthGPT generates a passage consisting of 210 words, significantly surpassing the original text’s length of 103 words. Despite the additional 107 words, the revised content demonstrates a noticeable decrease in precision, clarity, and emphasis on sustainability compared to the original, potentially compromising the overall quality of the text.

Although the quality of the content is suboptimal, it is crucial to evaluate the effectiveness of StealthGPT in rendering AI-generated text undetectable. To assess this, we subjected the humanized text to 5 leading AI detection tools available in the market.

StealthGPT vs ZeroGPT

StealthGPT’s rewritten text get a 86.14% AI score onZeroGPT, which is high enough to be viewed as AI-generated.

StealthGPT vs GPTZero

GPTZero exhibited even greater sensitivity, revealing that StealthGPT had a 96% probability of being AI-generated, with every sentence identified as generated by AI.

StealthGPT vs Originality.ai

Although GPTZero has a slightly higher AI detection score than StealthGPT, Originality.ai provided an 83% AI detection score for StealthGPT.

StealthGPT vs Content at Scale

Content at Scale does not have a specific AI detection score, yet it indicates that the text humanized by StealthGPT resembles AI, with highlighted sentences strengthening this probability.

StealthGPT vs Writer

It gets a 21% human score on Writer.com, which makes it look like AI-generated content on this detector.

Summary of StealthGPT Test Results

So, what are the results? We have compiled the AI detection scores from the five detectors in the table below:

In summary, StealthGPT faced challenges in bypassing AI detection across all tested tools, consistently receiving high AI scores. Combined with the mentioned suboptimal content quality, we do not recommend using StealthGPT to bypass AI detection.

Alternative Tool to Bypass AI Detection Instead of StealthGPT

Although StealthGPT may sound impressive and promising, its real-world performance leaves much to be desired. If you’re in search of an AI writing tool that is undetectable and performs better, AIHumanizer could be a viable alternative. Not only does it offer similar features, but it also delivers a more robust output.

AIHumanizer utilizes cutting-edge technology to humanize text content, allowing it to evade AI content detectors such as Originality.ai, GPTZero, Copyleaks, Turnitin, and Sapling. Unlike other tools that scramble words to the point of being unrecognizable, AIHumanizer retains the essence of your text. It surpasses StealthGPT in terms of undetectability.

You might even consider it to be more feature-rich. It offers a range of humanization levels, from fast to enhanced. Additionally, it includes a built-in AI check that provides the likelihood of the output content being detected by multiple AI detectors. AIHumanizer supports AI-generated text in over 50 languages, ensuring that your content is effectively humanized.

Does AIHumanizer Truly Make AI Content Undetectable?

Actions speak louder than words. To determine the actual effectiveness of AIHumanizer in making AI content undetectable, we conducted a test using the same ChatGPT content that was previously evaluated with StealthGPT. Here are the results obtained from AIHumanizer:

The AI checker built into the system suggests that the output content may be recognized as human-written by other AI checkers. To confirm this, we conducted AI detection tests using the same five detectors used for StealthGPT.

AIHumanizer vs ZeroGPT

ZeroGPT gives the AIHumanizer text a 0% AI score, which means ZeroGPT considers the content as completely human-written.

AIHumanizer vs GPTZero

GPTZero also provided an impressive 0% AI-generated score for AIHumanizer.

AIHumanizer vs Originality.ai

Originality.ai yielded another 0% AI detection score for AIHumanizer.

AIHumanizer vs Content at Scale

The AIHumanizer text passes the Content at Scale’s check as human written.

AIHumanizer vs Writer

Writer.com awarded AIHumanizer a commendable score, with 98% content generated by humans and a 2% likelihood of AI-generated content.

Effectiveness Compared

To further analyze the results, we have compiled the AI detection scores from five detectors for both AIHumanizer and StealthGPT in the table below:

Clearly, AIHumanizer effectively evades AI detection across the five detectors used in our test. We are highly confident that this capability can be expanded to other popular AI detection tools on the market, including but not limited to Turnitin, Sapling, Copyleaks, Scribbr, and more.

In contrast, StealthGPT consistently fails to bypass major AI detectors, receiving high AI scores from all five detectors. If your aim is to effectively bypass AI detection, the results indicate that AIHumanizer is the preferred tool over StealthGPT.

Final Thoughts — Is This Tool Suitable for You?

While StealthGPT is designed to generate undetectable AI content, its test results are not quite as expected. The generated content is twice as long as the original text, and there is a noticeable decline in content quality. Furthermore, not a single AI detector was fooled by its output content.

All things considered, it seems that StealthGPT may not be the ideal choice for those seeking a truly undetectable AI writing tool. It is recommended to explore more powerful alternatives to StealthGPT, such as AIHumanizer, that can deliver genuinely undetectable AI content.
