I don’t advocate using AI to write content, but sometimes it can help you articulate your point better. However, spotting AI-written content is extremely easy, since it uses nuanced words, em dashes, and too much unnecessary fluff. That is why I set out to find the best AI humanizers that can help your content sound human-written, and after testing over 40 tools, here are the ones I would recommend.

Best AI Humanizers Compared
I tried to find the best AI humanizers that are available for free, since they will be more helpful for students. However, I had to include some paid tools because they offer better quality and are worth their price. So that being said, here’s a list of the best AI humanizers to bypass AI detectors.
1. Clever AI Humanizer
Clever AI Humanizer is the best option to make any piece of content sound more human. That’s because it offers a very generous free plan, with 200,000 word limit per month, which is over 6,000 words per day. Plus, it doesn’t just add mistakes or remove em dashes. Instead, Clever AI Humanizer preserves the integrity of the content while improving grammar and readability. Essentially, you get more reliable results every time, and it also highlights the changes it has made.
| Pros | Cons |
|---|---|
| Reliable AI humanization every time | Basic tool with limited text customization |
| Mostly scores zero in AI detectors | |
| Offers 200,000 word limit per month for free | |
| Features text formatting options |
Pricing: Free
2. StealthWriter.ai
StealthWriter is the most advanced AI humanizer tool that I have tried, and it offers most of its services for free. It lets you freeze certain words from being rephrased, pick between different models, adjust humanization levels, and change the text style. It even lets you pick the strictest AI detector, so you can see whether the humanized content still shows as AI or not.
StealthWriter also generates not just one but up to five different drafts, so you can pick and choose which one to go with. Best of all, its content passed all my AI detectors. And I like the fact that you can humanize 20 copies per day of 1,000 words each. This is even more than what the Clever AI Humanizer offers per day.
| Pros | Cons |
|---|---|
| Up to 20 humanization of 1,00o words each | Does not support multiple languages |
| Pick different models | Pro model is not available in the free version |
| Lets you adjust the writing style | Could make mistakes in complex sentences |
| Can create multiple drafts |
Pricing: Free, Basic plan available for $20/month
3. RewriterPro.ai
What really separates human content from AI is emotion, the thought behind it, and the tone. Thankfully, RewriterPro lets you adjust all of that and paraphrases AI writing according to your choices. So you can transform bland AI-generated text to sound emotional and sympathetic or optimistic.
So your teachers or colleagues don’t have a shadow of doubt that it was a work of AI. This AI humanizer lets you rephrase up to five copies per day in the free version, making it suitable for students and professionals alike.
| Pros | Cons |
|---|---|
| Lets you pick emotion, tone, and fluency | Limited access to features in the free version |
| Offers up to 5 rephrasing per day for free | |
| Very good at humanizing AI content | |
| Supports multi-language paraphrasing |
Pricing: Free, paid plan starts at $9.95/month
4. Humanzier Pro
Humanizer Pro is a handy tool if you want jargon from ChatGPT or Gemini to sound like human writing. It clears up unnecessary fluff, cutting straight to the point and delivering a natural-sounding version. You can paste up to an 80-word paragraph in the free version, but the Pro plans unlock larger text support. Humanizer Pro also gives you a human score right below, so you can be confident that no AI detector will catch the humanized text.
| Pros | Cons |
|---|---|
| Easy to operate tool | Word limit on the free plan |
| Gives a human score for every humanized text | |
| Cuts down on unnecessary material |
Pricing: Free, Basic plan starts at $12/month
5. Writehuman.ai
Another good option that I have found is Writehuman.ai. This tool also converts AI wording to natural one and does a pretty convincing job at that. It lets you choose the tone of the content, so it sounds more human, and lets you use an enhanced model to trick most AI detectors out there. It does not guarantee a 100% human score, but it has fooled most detectors that I tested out compared to other AI humanizers.
| Pros | Cons |
|---|---|
| Writes convincingly human text | Free option only offers 200 words rephrasing |
| Tricks several AI detectors | Enhanced model locked behind paid plans |
| Lets you customize the tone | Lacks deeper customization of text |
| Shows human score of rewritten text |
Pricing: Free, Basic plan starts at $18/month
6. GPTinf
GPTinf is the best AI Humanizer, specifically for students and researchers, because it offers the ability to ‘Freeze’ or skip certain words from being rewritten. It lets you adjust the tone of the text and checks the humanized content across several detectors. Why I liked GPTinf is that it doesn’t just simplify AI writing, but also improves it, making it read more like genuine human writing. However, the free version only allows you to paste 120 words at a time.
| Pros | Cons |
|---|---|
| Pick the tone for the content | Word limit under the free version |
| Checks rewritten content across several detectors | Pay to get access to features like selective rephrasing and unlimited word freezing |
| Improves readability of text | |
| Simple design and easy to use |
Pricing: Free, Lite plan starts at $9.99/month
7. QuillBot Humanizer
You might have heard about QuillBot since it is such a popular paraphrasing tool. But did you know, it also has its own AI Humanizer, which can effectively replace ChatGPT, Gemini, or Copilot-generated fluff with simpler wording.
It has support for different English dialects and 4 other languages. Plus, you can also pick between a Clear and a Formal tone in the free version. While it didn’t pass some of the AI detection tools in my tests, it still managed to do a fairly good job, which is why I added QuillBot to this list.
| Pros | Cons |
|---|---|
| Lets you directly upload documents for quick rewrite | More advanced tone settings are exclusive to the paid plan only |
| Support for up to 8 different languages | Limited text customization options |
| Can change the tone of the content | |
| Generous free tool |
Pricing: Free, Paid plan available for $50.07/year
These are the best AI humanizer tools that are available out there. All of them are quite competent in turning AI-generated writing into human-like text. If you have any suggestions or think that I missed any tool that you highly recommend, then let us know in the comments section below.
