Humanize AI Pro Review: Can It Really Trick AI Detectors?

Humanize AI Pro (Humanizeai.pro) is an AI text “humanizer” that attempts to turn ordinary, AI-generated text into a more human-sounding and human-written version. 

We decided to put it to the test and see if it really can make AI-generated text undetectable by testing its text against Originality.ai’s AI detector as well as ZeroGPT and Writer. 

See the results of our comparative test in the review.

What is Humanize AI? 

Humanize AI is a tool that offers several different methods to make AI-generated text sound more human. The free version of the tool offers a ‘standard’ humanization option. However, upon registration, it highlights additional humanization features including: formal or informal, shortening or lengthening it, or making the text sound more academic. 

For the purpose of this test, we selected the standard option, as choosing any of the other options required registration.

Humanize AI Pro works on a credit-based system, and registering unlocks 1500 credits.

Why is there interest in Humanize AI?

Content creators, business owners and other professionals who rely on AI tools like ChatGPT, Claude, Jasper, and Google Gemini often want to avoid having their content labeled as “AI-generated.”

This may be due to a number of reasons. For instance, AI content that doesn’t comply with spam policies may result in Google penalties.

So tools that could potentially humanize text are becoming increasingly popular.

In particular, Humanize AI Pro claims to beat or bypass popular AI detectors including Originality.ai so we decided to see if it could live up to its claim. 

Does It Work? The Results

The Test:

This test was designed to see if the AI text that was run through the HumanizeAI Pro tool and was “humanized” could bypass ZeroGPT, Writer AI and the Originality.ai AI content detector. 

Step 1: First, we generated around 500 words of text on a random topic in ChatGPT. This was done to ensure that the text that would be put into Humanize AI Pro would be 100% AI written as the foundation. 

Step 2: We then ran the AI-generated text through Originality.ai, ZeroGPT, and Writer AI to get a base score.

Step 3: We pasted the same AI-generated text into Humanize AI Pro and had the platform humanize it according to the standard selection of their tool

Step 4: We then pasted the humanized AI text into ZeroGPT, Writer AI, and Originality.ai to see if it could successfully detect the text as having been AI-generated or not. 

The Results

Originality.ai Score

Original content (AI-generated): 100% Confidence that the text is Likely AI

Humanize AI Pro Version: 100% Confidence that the text is Likely AI

Writer Score

Original content (AI-generated): 78% Human-generated, 22% AI-generated

Humanize AI Pro Version: 95% Human-generated, 5% AI-generated

ZeroGPT Score

Original content (AI-generated): 98.9% AI-generated 

Humanize AI Pro Version: 69.4% AI-Generated

As you can see from the test results, Humanize AI Pro was unable to humanize the AI-generated text sufficiently to avoid detection by Originality.ai. 

The Originality.ai AI content detector was able to spot the AI-generated text with an incredibly high degree of accuracy, even though the original text had been altered by the AI humanizer. 

So, is Humanize AI Pro’s text indistinguishable from human-written text? Our test results indicate that it is still detectable as AI-generated.

The industry-leading Originality.ai AI Checker can still identify the humanized version of Humanize AI Pro’s text as Likely AI with 100% confidence. 

Final Thoughts

If you’re planning to use Humanize AI Pro to humanize content, keep in mind that while it does switch up some of the words, it is still detectable by the best-in-class Originality.ai AI Checker.

AI is great for helping with a number of writing tasks such as creating outlines or content briefs and brainstorming ideas, yet it’s best as a support to authentic human-written people-first content.

FAQs About Humanize AI

What is Humanize AI Pro?

Humanize AI Pro is an online tool designed to bypass AI content detectors and “humanize” text generated by GPT tools including ChatGPT, Jasper, Copy AI, Google Gemini and others. It does this through a series of online edits and then presents a finalized result that shows the user, via color-coded text what has been edited and to what degree. 

Can Humanize AI Pro make AI text undetectable? 

We tested if Humanize AI Pro could humanize text to make it undetectable, and the end result was that Originality.ai was able to discern with 100% confidence that the text was AI-generated. 

Is Humanize AI free to use?

Standard text conversion from AI to humanized text is free to use. However, if you would like to use any of the other modes, including academic, formal or informal humanization, or if you would like to expand or shorten the text, you will need to register.
