4 AI-Powered Tools to Make AI Text Undetectable in 2025!
AI generative tools are constantly evolving and are becoming increasingly smart in their work.
The content you get using AI is very much similar to that of a human writer and is logically accurate, but the problem is that AI detector tools are also getting more sophisticated and capable of identifying AI-written or even AI paraphrased content.
Well, if you want to ensure that your work is undetectable, you can always get help from AI Humanizers!
These are online tools that rely on advanced rewriting techniques to add a human touch to your robotic text. The main function of these tools is to make AI text sound more natural and authentic. Today, there are hundreds of AI text humanizer tools listed on the search results of Google, but sadly, not all of them are perfect.
This is why, after thorough testing and experimenting with dozens of popular AI humanizers, we have compiled a list of the 4 Best AI Humanizers for 2025. So if you want to bypass AI detection and get maximum human score, we’ll urge you to read this article till the end.
We’re getting to the list in a bit, first let’s start with the basics…
What are AI Text Humanizers?
AI humanizer tools are cloud-based utilities that are trained on large datasets and use deep learning technologies to understand and identify robotic elements in AI-generated text and NLP to transform such text into a more natural-sounding, digestible, engaging, and authentic draft.
Humanizer tools don’t just spin words with synonyms like conventional paraphrasing tools; rather, these tools make modifications to the tone, structure, style, and complete language of text. These tools can easily make the humanized version sound more realistic and polished.
Modern AI humanizer tools use machine learning models to fine-tune text. These not only help in evading detection tools but also in personalizing text, introducing minor errors, and ensuring originality, so that the new version sounds as if written by a human writer.
Now that you know what humanizer tools are, let’s discuss the top four utilities.
4 Best Humanizer Tools to Make AI Text Undetectable in 2025
We created a passage using ChatGPT (attached below) and checked it with ZeroGPT & Copyleaks.
1. HumanizeAI.Net (Free Detection Defeater)
HumanizeAI.net is one of the most reliable humanizing solutions that can easily outsmart detector tools.
We humanized the GPT-generated passage with this tool, and it got over 99% human score, which was quite impressive because we used the free version!
This AI text humanizer is specifically designed for professional writers, marketers, and students who heavily rely on AI tools for content creation. The tool uses natural language processing techniques to understand and modify AI-generated text while preserving its original intent and underlying message.
The best thing about this tool is that it makes text simple, natural, and engaging for even a fifth grader. This is what makes it ideal for rewriting blogs, assignments, marketing copies, and other textual material generated via AI.
The tool comes with a simple interface, which makes it an attractive option for beginners as well as technical experts. Moreover, the free version of the tool allows you to humanize up to 500 words in one go, which is ideal for humanizing a basic AI draft.
Note that the text humanized through this tool bypasses all advanced detection tools, including Copyleaks, Winston, Sapling, Cross Plan, Content at Scale, and many others.
Pros
- Beginner-friendly interface
- Decent free version
- Secures over 95% human score
- Works on every device
- Can humanize different content types
Cons
- No built-in AI detection tool
- No tone selection options
- No mode varieties
Pricing: The weekly plan costs you around $4.95, $9.95 for a month, and $50 for an annual subscription.
2. QuillBot’s Humanizer Tool (Runner Up)
QuillBot’s AI Humanizer is one of the latest additions on the website and is getting very popular because of its NLP capabilities. The tool can easily make changes such as replacing robotic terms with simple words, changing the style & tone, and making other structural amends which would make the new text less predictable and more natural.
This humanizer tool is very easy to use, and the working process is similar to that of the paraphrasing tool of QuillBot. This also means that you can only humanize up to 125 words in one go, which is very little compared to our winning utility.
As for the results, the humanizer by Quillbot surely creates text that sounds more fluent and natural, but the problem is that the humanized version bypasses free detection tools, and surprisingly fails to outsmart the very AI detector tool of Quillbot itself. The AI detector of Quillbot can easily identify that the AI text has been edited, so you might have to make manual changes to bypass the advanced detection programs.
Here, we would like you to know about a trick that we tried. Once we got a low human score through the AI detector tool of Quillbot, we tried paraphrasing the humanized version with the paraphrase tool and tested the new version again. This time we got over 85% human score, which is good enough.
Pros
- No limits on the number of uses
- Simple interface
- Works perfectly in the English language
- Humanized plus plagiarism-free results
- Built-in AI detector & other helpful tools
Cons
- The humanized version might need manual editing to trick advanced detectors.
- Only available for English language users
Pricing: The premium plan of QuillBot’s AI humanizer would cost you around $4.20 every month!
3. HumanizeAIText.co (Best Contender Overall)
Humanizeaitext.co is the third one on this list, but we feel like its results are better than those of QuillBot’s, which is why we have labeled it as the best contender.
There are multiple reasons why we have included this humanizer tool on this list. First of all, we were surprised to see that the free version of this tool allows you to humanize up to 1000 words in one go, which is quite impressive. Users who want to humanize lengthy assignments, essays, blogs, and even newsletters can use this free tool and get a natural-sounding version in mere seconds.
The humanizing speed of this tool is also brilliant. It can humanize a thousand-word piece in less than three to five seconds. So if you want to get natural and human-toned content in minimal time, you should try this tool.
Another good thing about this tool is that it works in over ten major global languages, which makes it an attractive option for users creating content in different languages for different audiences using AI.
We tried humanizing not just the GPT-generated draft with this tool, instead we also created content from Grok, Gemini, and DeepSeek and humanized it with this tool. It easily edited and revised the robotic elements and provided over 90% human score every time.
Pros
- Natural and emotion-driven language
- Context retention
- Constant updates and improvements
- Impressive free version
- Works in multiple languages
Cons
- No offline version available
- Limited number of uses
- Expensive premium packages
Pricing: The premium plans would cost you around $18/Month and $53 for a year!
4. SurferSEO’s Free Content Humanizer Tool
AI humanizer by SurferSeo comes last on this list, but is certainly not less than any other utility in terms of accuracy and quality of text it produces. This humanizer tool easily changes AI content in such a way that it looks like it was written by a real person. The tool uses sentence and style patterns copied from human writers so that the new text gives a natural vibe.
The goal of this text humanizer is to make sure that the humanized version bypasses AI detection tools, and for that, it makes all necessary changes. All excessively used AI terms would be removed, sentence length would be modified, use of passive voice would be removed, minor errors would be introduced, and the tone would also be changed so that the new text can outsmart both basic and advanced detector tools.
The thing we like most about this humanizer is that it allows you to humanize up to 20,000 words in one go for free. This limit makes it a lucrative option for students and research paper writers who have to edit thousands of words in one go while protecting the context.
You just have to paste the AI-generated text, and the tool will humanize it in real time before your eyes. The humanized version would be written to you before, and once the process is complete, the tool would give it a final scan and would give you a probable score. Overall, this is a very helpful tool for making AI text undetectable.
Pros
- High quality and unique results
- Maximum human score
- 20,000-word processing for free
- Ideal for different content types
- Works in multiple languages
Cons
- The interface might be a bit complicated for first-time users
- Paid packages are quite expensive
Pricing: The monthly packages for individual users would cost you around $80 to $175.
