In recent years, AI-generated content has played an increasingly important role in people's writing, marketing, and SEO optimization. However, how to make AI-written articles more "human" so as to bypass AI detectors and obtain a more natural reading experience has always been the focus of content creators.
Today, I will review a popular AI text humanization tool - Grubby AI Humanizer. We will see together whether it is worth using and how it actually works. At the same time, I will also recommend several alternative tools with better experience to help you find the most suitable AI humanizer solution.
Grubby AI is an online AI text humanization tool. Its main function is to "humanize" AI-generated texts, aiming to improve the naturalness and readability of the content, and help the text pass the inspection of AI content detection tools (such as GPTZero, Originality.ai, Turnitin, etc.).
Grubby AI offers four different plans to suit different needs from casual users to professional content creators. Here are its prices and features.

To evaluate its actual effect, I input a standard explanatory text written by GPT-4 into Grubby AI and observe the results.
Artificial Intelligence has become a powerful tool in content creation. It enables users to generate text quickly and efficiently. However, it often lacks the nuance and warmth of human writing.
Content creation has changed drastically thanks to AI. It's fast, efficient, and super helpful. But let’s be honest—it still can’t match the subtle touch and feeling of something written by a real person.

Summary: Grubby AI is more suitable as a temporary rewriting tool. Its output style has a certain "content creator" tone, which is suitable for blogs, soft articles and SEO articles. However, it is not stable enough for academic purposes or scenarios that require 100% bypassing AI detection.
For students, Humanize AI is a more cost-effective option that excels at bypassing detection tools like GPTZero and Turnitin, making it a go-to tool for generating high-quality content that is difficult to detect.
I decided to test the performance of Grubby AI and Humanize AI against each other using several different types of text content to fully evaluate their abilities to humanize and bypass AI detection.

Grubby AI Text Humanizer is a powerful text rewriting tool, especially for those who need to bypass AI detection tools. If your goal is to quickly generate relatively natural text and have the need to bypass detection, Grubby AI is a worthy choice. However, if you need a higher level of detection bypass, or a more natural and personalized output, you may want to consider other tools such as Humanize AI, which provides higher reliability and results in this regard.
In general, Grubby AI is suitable for users who have basic needs for detection bypass, but do not need the highest quality natural writing. If you are a creator or student who frequently needs to generate high-quality humanized content, you may prefer to choose Humanize AI, which has more comprehensive functions and stronger detection bypass capabilities.
