I put AI Humanize Text Humanizer to a test with three AI-generated text samples.
In this post, I’ll test and give an overall review of the tool, and show the results. In my reviews, I emphasize the ease of use, and will only test free tools or tools with Free trials.

How to Use It
Here is how to get started with AI Humanize. Enter their website and you can access the humanizer directly.
You can just paste your text there.

You can even modify the output with these settings. The Autopilot Pro is available for the Premium plans only.




My Results
I asked ChatGPT to generate three different text samples on random topics; you can find them at the end of this post. Then, I humanized the texts using Humanize AI and ran a separate AI detection scan on Undetectable AI to see their AI scores after humanizing. You can modify the output to target different audiences by changing the purpose, length, and tone.
Let’s see the results then, for the first text sample. The words highlighted in purple were changed in the humanization process.

Next, I ran an external AI Detection scan on the humanized text to see if it would pass as human-generated content. The first sample received an AI Probability percentage of 67 %.

The free version of the AI Humanizer has a word limit of 200 words. Here are the results for the second text sample.


At first glance, it seems that this time the humanizer was successful, but it actually started the generation mid-sentence for some reason, probably due to the word limit.
So I generated a new humanized text and ran the AI Detection scan again. I noticed some grammar errors like “Coffe”, don’t know if it’s intentional to make the text sound more human or not.

Here are the AI Detection scan results from the last text sample.

Overall, not the worst result, but it seems like the tool made some grammar mistakes. If you’re using this tool, it’s worth reading through the humanized output to check for any errors.
With the free plan, you have 2000 words in total to Humanize.

Pros
- Easy to use, no sign-up needed
- Allows you to do some minor adjustments to the output
Cons
- 1/3 of my texts passed as human-generated
- Can only humanize a maximum of 200 words per generation
Pricing
Here are the pricing plans AI Humanize offers.

In Summary
AI Humanize is an advanced AI Text Humanizer that rewrites your text to bypass all AI Detectors, including Turnitin and Copyleak.
I tested the free version of the AI Humanizer feature with my AI-generated text samples. The tool has a word limit of 200 words per generation, and very short texts tend to get flagged as AI easier.
Only 1/3 of my texts passed as human-generated content after humanization. I noticed that in this case, the tool didn’t generate a coherent paragraph, but started generating mid-sentence. With the free plan, you can humanize up to 2000 words in total. I can’t recommend the free version based on my experience.
On a sidenote, the names of these tools are awfully similar.
AI humanizers try to make AI-generated text sound more “human” by tweaking phrasing structure and tone. Some even promise refunds if your text gets flagged as AI.
Honestly, these tools aren’t very reliable and don’t really add much value. If you must use content generated by ChatGPT, it’s much better to edit and polish it yourself than try to trick a detection system.
