Can Grammarly Humanize AI Text? We Put It to the Test

With AI writing assistants like ChatGPT becoming increasingly powerful, it's no surprise that people are now looking for ways to "humanize" the output, especially when passing AI detection tools is necessary. Grammarly, already a leader in grammar and style assistance, has introduced a free AI humanizer tool. But the real question is: Can Grammarly humanize ai text effectively ?

We decided to test it out by running a sample paragraph through Grammarly's Humanizer, then checked how well it fared using Grammarly's own AI detector. The results were surprising, and even more so when we compared them to other tools.

Grammarly AI Humanizer is a free online tool designed to transform robotic, AI-generated writing into more natural, human-sounding content. Whether you're using ChatGPT, Bard, or any other AI writing assistant, this tool helps make your output feel less mechanical and more authentic---perfect for emails, essays, social posts, and more.

Can Grammarly Humanize AI Text Well?

We conducted a simple test: we asked ChatGPT to generate a descriptive paragraph about a sunrise at the seaside.

Next, we ran the paragraph through Grammarly's AI Humanizer to see how well it could improve the naturalness and flow of the text.

To assess the effectiveness of the rewrite, we used Grammarly's own AI detector to see whether the text appeared more human-like.

Result: 100% AI-Generated

While Grammarly's AI Humanizer aims to enhance tone and readability, not bypass AI detectors, we used its own detector as a direct way to evaluate how human-like the rewritten text appeared. Although the output was more natural, it was still flagged as 100% AI-generated, offering a helpful reference for how effectively the tool humanizes AI content.

If your goal is to pass AI detection, not just polish your content, you may want to explore other tools. Here's one that stood out in our tests.

We used Tenorshare AI Bypass to rewrite the exact same ChatGPT-generated paragraph. Here's the output:

When we tested this version in Grammarly's AI detector:

Result: 0% AI-Generated

We didn't stop there. To validate the human-likeness of the rewritten content, we also ran it through GPTZero, another popular AI detection tool used by educators and professionals.

Result: 100% Human

This dual detection success suggests that Tenorshare AI Bypass is not only effective at avoiding AI detection but also excels at crafting genuinely human-like writing.
