AI text generator tools have gained a lot of popularity in the past few years, but you would be surprised to know that the content produced by these popular LLMs is easily detectable.
AI detector tools can easily differentiate AI-generated text from a human-written piece. This is mainly because LLMs are trained on data that is generated by AI. This training process is generally known as AI poisoning, and it has made it impossible for GPT users to get away with machine-written text.
If you’re heavily relying on AI tools for managing your writing tasks, you don’t have to stress much about AI detector tools, as today, you also have access to free tools that can adjust outputs generated by AI chatbots and make them undetectable. These tools are commonly referred to as AI humanizers.
In this guide, we are going to list out the best tools that can help you with AI writing. So if you really want to make your text undetectable and easy to understand, read on.
What are AI Text Humanizer Tools?
Humanizer tools are web-based solutions that can easily edit and adjust machine-written text and make it sound more natural and engaging for readers.
These tools can easily identify robotic elements and make necessary amends to make the new version sound more human and authentic.
AI text humanizers can ensure that your text bypasses AI detection, which is why they are getting more and more popular every day. Now there are dozens of AI humanizers listed on the search results of Google, but sadly, not all of them are reliable or capable of making contextually accurate changes.
Therefore, after thorough testing and trials, we have compiled a list of the best tools for modifying AI-generated text.
Best Tools to Humanize AI-Generated Text in 2025
We suggest you try out the below-listed utilities and choose the one that provides the most satisfactory results.
Humanizeai.net
Humanizeai.net is one of the most reliable solutions as it specializes in converting technical AI-generated content into text that sounds more conversational and digestible. The tool would look for common AI patterns and would replace them with more natural phrasing while keeping intact the underlying context.
The tool is ideal for humanizing sentence structure and adding variety to text that otherwise sounds fake and robotic. A good thing about this tool is that it is available for free, so you can use it whenever you want without going through any technical signups or buying subscriptions.
The tool is very easy to use, and even a new user without any prior experience or training can use this tool like an expert. All you have to do is upload the text in the input box and hit the “Humanize Text” button. The free version allows you to humanize up to 500 words in one go, which is what makes it a catchy choice.
By making linguistic and stylistic changes in the text, this AI humanizer tool can easily bypass all popular content detector tools, including GPT Zero, Sapling, Winston AI, Turnitin, Copyleaks, and many others. The humanized text would not just bypass these tools, but it would also be more engaging and digestible for readers.
What we liked most about this tool was its ability to add appropriate emotional language to robotic and generic text.
Ahrefs Free AI Humanizer
The humanizer tool by Ahrefs is another straightforward utility that can humanize AI-generated text. This tool doesn’t rewrite the AI text completely, rather, it focuses on making subtle changes that would be enough for tricking AI detector tools.
The main focus of this tool is to eliminate all robotic elements from text and to make it sound more direct and fluent.
Unlike many other overrated utilities, you don’t have to worry about any technical installations or downloads to use this tool, as it works directly in your browser. You can use it on any device you want as long as you have a stable connection.
The thing we liked most about this text humanizer is that it allows you to revise up to 2000 characters in one go. In addition to this, you can select how many versions you want the tool to create.
The tool can generate 1, 3, and 5 variants for free. You would get all humanized variants in less than a second. You can go through the different versions and choose the one that sounds most natural.
Other than humanizing text, it also ensures that all grammatical errors and typos are removed.
HumanizeAIText.co
HumanizeAIText.co is the third one on this list and is also one of the best solutions for maintaining readability and engagement. The tool relies on natural language processing and machine learning to identify and transform AI-generated text.
The humanized version generated by this tool would always sound organic, natural, and authentic. The tool offers basic humanizing features in the free version, which are enough for humanizing all kinds of texts, such as blogs, emails, assignments, etc.
Users can easily humanize up to 1000 words in one go, which is quite impressive for a free tool. Another good thing about this tool is that it works in different languages, including English, Dutch, Spanish, Portuguese, and many others. This makes it an ideal choice for users creating content in different languages using AI tools.
What we liked most about this tool is that it is very effective in reducing AI detection scores. We always got over 90% human score when scanning it with Turnitin, Copyleaks, and other advanced solutions.
GPT Human
GPT Human is the last one on this list, but it is surely very valuable for bypassing AI detection. The tool has been created by a team of LM engineers who have also worked on creating multiple AI detector tools.
By knowing the exact scanning process of AI detector tools, they have designed a text humanizer that has the ability to bypass almost every AI detector tool, free or paid.
GPT Human doesn’t just make changes to trick AI detector tools, but it also ensures that the humanized version is original and easy to read. We have tried testing multiple types of texts with this tool, and we always go over 95% human score.
The tool comes with a free trial, but what we don’t like about it is that its premium packages are a bit expensive compared to other utilities in this league.
Final Words
AI writing tools are no doubt valuable for improving efficiency and productivity, but you must know that text generated by AI tools can easily get flagged by AI detection programs. This is why it is important to use AI text humanizers before using text on a commercial platform or when submitting it as your original submission.
In this guide, we have listed the four best humanizer tools that can help you adjust machine-written text and make it sound more natural and authentic. We hope that after using these tools, you will be able to find the best one for your needs.
Share your experience with these humanizers and let us know if we should add more to this list.
