Best AI Humanizer for Writers in 2026

Quick Answer: The best AI humanizer is ReHumanize AI. Why? You’ll find out during the course of this blog.

You have spent a lot of time writing an amazing article. Your research is impressive, the SEO is good, and you’ve followed the content brief.

Still, when you or your client ran it through an AI checker, it flagged your content as “AI-generated.” We’ve all been there!

In fact, this is still something many content writers struggle with every day. With Google penalizing AI-generated content, business owners are unwilling to take any risks.

They want their content to rank on Google and engage real readers, not sound generic and robotic. The question is, what’s the best way around this? 

This is where using an AI humanizer becomes an excellent option. After all, AI writing tools produce content that sounds robotic and unnatural.

In contrast, humanizers ensure articles flow well and engage readers by mimicking natural human writing.

But as you’ve noticed, it’s not always smooth sailing using AI humanizer, even though there are so many of these tools on the market. So, how do you know the best tool for the job?

Well, I tested 20 different AI humanizers extensively and found only five that work well. In this post, I’ll walk you through why these five stand out by looking at their features, pricing, pros, and drawbacks.

By the end of this review, you’ll be able to make a more informed choice on the best AI humanizer for your needs!

What is an AI Humanizer?

If you have ever used an AI writing tool, you know that the content it produces can sound quite robotic. This is because these tools rely on specific patterns and phrases, which can make articles seem dull or unnatural.

AI humanizer removes the predictable phrasing used by standard AI writing tools. It replaces it with more natural human language, making your articles more engaging while also helping them bypass AI detectors.

Factors to Consider When Choosing the Best AI Humanizer for Writers 

As someone who has tested lots of AI humanizers extensively, I can tell you one thing: not all of these tools are created equal. Here are five things I think you should look for when choosing an AI humanizer

Bypasses all major detectors

If you’re reading this, chances are that you don’t want your AI-generated content to be detected. Making sure your content passes all major AI detection tests is probably the number one thing I look for when testing these humanizers.

I tested each tool against some of the biggest names in AI detection, including GPTZero, Copyleaks, and Turnitin; if they couldn’t pass these tests, then they weren’t any good!

Content quality

Just because something passes AI detection tests doesn’t mean it’s any good. When testing these tools, I looked closely at how well they preserved my original meaning while still sounding natural. In other words, did they produce content with a good flow and rhythm?

It’s very important that the tool produces readable, undetectable AI content without grammatical errors or weird phrasing.

SEO

If you are a web publisher, AI content needs to rank. Many rewriters strip out your carefully chosen keywords in an attempt to humanize text. This hurts your search visibility. A good AI humanizer tool understands the importance of SEO.

It should preserve your primary keywords while changing the surrounding text. This ensures you can humanize AI text without losing your hard-earned Google rankings.

Rewrite loop

This is a feature many people overlook until it costs them money. Sometimes, the first output isn’t perfect. You might need to run it again. Some AI tools charge you for every single attempt, eating into your word count.

The best ai humanizer tools offer a free rewrite loop. This means if the first result isn’t great, you can retry without spending extra credits. It is vital for refining AI-generated text.

Pricing

Cost is always a factor. You will find everything from a free AI humanizer tool to expensive enterprise software. You need to balance affordability with features. I evaluated ai humanizer pricing plans to see who offers the best value.

We will look at the cost per word and whether the plans are flexible for freelancers or students. Ai humanizer tool reviews often skip this, but I will break it down clearly.

5 Best Humanize AI to Bypass AI Detectors in 2026

I have tested these tools extensively. I got the paid plans, and I tried these tools with several articles. Here is my honest breakdown of the top 5 best AI humanizer tools available right now.

1. Rehumanize AI

ReHumanize AI stands out from the pack in the industry, delivering nothing but what it claims. It doesn’t try to be a jack-of-all-trades; it focuses entirely on being the best humanizer for AI.

Here is a breakdown of the features that make it special:

Bypassing Major Detectors: I threw everything at this tool. It successfully bypassed GPTZero, Copyleaks, ZeroGPT, the Quilbot AI detector, and Turnitin. It is a robust AI humanizer tool that consistently gets green scores.

SEO Preservation: This is a game-changer. ReHumanize AI keeps your important keywords so you can rank higher while staying undetectable. A lot of AI humanizers fall short here, scrambling your keywords and hurting your SEO strategy.

Maintaining Content Quality: You have to understand how some AI humanizers bypass AI. They only manage that because the content quality is really nothing to write home about. They produce broken sentences and weird phrasing. But with ReHumanize AI, they get no broken sentences, no weird phrasing. Just natural, flowing human-like writing.

Free Rewrite Loop: This is a major boost for affordability. While other AI humanizers deduct words each time you run the same text through, ReHumanize AI won’t use up more of your word allowance. Repeated re-processing doesn’t count as extra usage. A lot of the tools out there just make you spend your word limit quickly, but this feature saves you money.

ReHumanize AI Pricing

ReHumanize AI offers a really affordable plan, ensuring anyone, from freelancers to writers to agencies, can benefit from the tool.

• Starter Plan: The pricing starts at just $9 for 25,000 words.
• Standard Plan: This costs $18 for 50,000 words, which should be more than enough for most freelance writers.
• Pro Plan: This goes for $30 for 85,000 words.

 There is no Unlimited plan. But the 85,000-word pro plan at just $30 makes up massively for this, not to mention they provide a free rewrite loop. Also, the yearly plans give users a 40% discount on all paid plans.

There is a free AI text humanizer option available on their Free Forever plan, allowing users to humanize AI content for 700 words per month. This is great to at least try out the tool. The tool offers three writing styles (casual, conversational, and formal) for users to choose from, a very clean editor, and formatting functions.

Pros of ReHumanize AI:

• Excellent at bypassing AI detectors.
• Preserves SEO keywords perfectly.
• High-quality, natural writing output.
• Free rewrite loop saves credits.
• Very affordable starter plans.
• Clean, user-friendly interface.
• Offers a free AI humanizer tool plan forever.

Cons of ReHumanize AI:

• No unlimited word plan available.
• No AI detector feature

2. WalterWrites AI

WalterWrites AI is another good AI humanizer tool to bypass detectors if you are looking for granular control. The first thing you notice is the clean editor and formatting functions.

You simply have to paste in your AI text on the left side of the editor, and then you’ll see your humanized text on the right side of the editor. It is intuitive and easy to use.

One standout feature is that the tool offers five different readability levels to match your target audience, alongside 11 different intended uses, which they tag “Purpose.” This allows you to tailor the voice, which helps make ChatGPT sound human. You can pick from three detection bypass levels: simple, standard, and enhanced.

However, with my observation using the tool, the higher the bypass level you choose, the poorer the writing quality gets. The aim seems to be to force bypassing AI detectors at the cost of flow.

The best bypass level is “simple,” where the content quality is good and still bypasses detectors. It struggles with bypassing GPTZero, Turnitin, and Copyleaks sometimes, but it consistently bypasses other AI detectors in the industry.

Another helpful feature it offers is an inbuilt AI detector, which, from our observation, is very reliable with the likes of Copyleaks and GPTZero.

WalterWrites AI Pricing

• Starter Plan: $12 gives you 30,000 words monthly.
• Pro Plan: $23 gives you 70,000 words.
• Unlimited Plan: They offer an Unlimited Plan for $47 monthly.

You get a 45% discount when switching to a yearly plan. There are a few other drawbacks of the tool, like no free rewriting loop. Struggling to bypass GPTZero and Copyleaks consistently could quickly use your allocated word limit, trying to humanize the same text over and over again.

Pros of WalterWrites:

• Good variety of readability levels.
• Specific “Purpose” settings help context.
• Clean editor with side-by-side view.
• Includes a reliable built-in detector.
• Offers an unlimited plan for power users.

Cons of WalterWrites:

• Quality drops significantly on high bypass settings.
• Struggles with tough detectors like Turnitin.
• No free rewrite loop eats up credits.

3. WriteHuman AI Humanizer

WriteHuman is a well-known name, but does it do a decent job if one is a writer who is open to a lot of edits on the generated text? When I tested it, it did get a very low score from AI detectors like ZeroGPT, GPTZero, and Copyleaks.

This sounds great, though the quality does drop quite a bit, especially on the enhanced model. The platform is very straightforward, and the functionality is very clear.

For those looking for an AI humanizer free, the functionality of the free plan is capped to 200 words per interaction. This is quite small for serious work. WriteHuman also offers a free AI detector that lets you check up to 1,200 words of content for AI.

I did perform free checks with the detector. Sadly, it’s not as advanced as major AI detectors like GPTZero and Copyleaks, so take the results with a grain of salt.

WriteHuman Pricing

The pricing of the paid plan is a bit different from the humanizers we’ve reviewed earlier. It operates on “requests.”

• Basic Plan: Offers 80 humanizer requests monthly, with up to 600 words per request for $18.
• Pro Plan: Costs $27, with 200 humanizer requests of up to 1,200 words per request.
• Ultra Plan: Costs $48 for unlimited requests per month, and you can humanize up to 3,000 words per request.

However, using the tool, I quickly discovered that trying to humanize 1,200 words or 3,000 words per request is not a good idea. The content quality becomes really poor with a lot of hallucinations. The best option is to choose any of the plans, but make sure you don’t go above 500 words per request for good quality.

Pros of WriteHuman:

• Simple, straightforward interface.
• It effectively bypasses some detectors.
• Unlimited requests are available on the top tier.
• Good for short snippets of text.
• Ai humanizer free trial available (limited).

Cons of WriteHuman:

• Request-based pricing can be confusing.
• Quality degrades heavily on long texts.
• The built-in detector isn’t very reliable.
• High rate of “hallucinations” in the text.

4. Undetectable AI

Undetectable.ai is a somewhat popular AI humanizer that offers an AI humanizer, AI detector, AI essay writer, and AI SEO writer. Our major concern using the tool was its ai humanizer text capabilities and detectors, so we didn’t pay attention to the other tools it offers.

Looking at the AI humanizer, they offer a three-day free trial for new users to test out the tool, but they require you to enter your card details, which will automatically charge you for the plan you choose after the 3-day trial ends. So, they don’t offer a forever-free plan. This is a barrier for those just wanting a quick AI humanizer free test.

One of the things we consistently noticed using the tool is the content quality, with occasional hallucinations and very poor grammar. You’ll find a humanization setting at the editor which offers three humanizer models (Basic, Stealth, and Undetectable).

I did notice when using the tool that choosing the Stealth or Undetectable model means you have to sacrifice content quality as the tool tries to force bypassing detectors.

You can also choose readability level, purpose, and human level, all at the same time. Does the tool bypass detectors? Yes, but most of the content makes little sense, especially when using the Stealth or Undetectable model.

Undectectable.ai Pricing

It’s one of the most expensive AI humanizer tools out there.

• 20,000 words monthly costs $19.
• 35,000 words cost $31.
• 50,000 words are priced at $42.

Actually, it’s the most expensive AI humanizer on our list. You’d have to pay $64 for 80,000 words. Compared to ReHumanize AI, where you pay just $30 for 85,000 words or $47 for Unlimited words, WalterWrites AI is very expensive.

Do we recommend this tool? Not really. It has more than quite a few drawbacks but is still a popular option out there for some reasons, perhaps vigorous promotion. It might work as an ai humanizer for essays if you have a big budget, but there are better options.

Pros of Undectectable.ai

• It does technically bypass detectors.
• Offers a suite of other tools (SEO, essay writer).

Cons of Undectectable.ai

• Very expensive compared to competitors.
• “Stealth” modes produce gibberish text.
• Requires a credit card for the trial.
• Poor grammar in the final output.
• No forever free plan.

5. Quilbot AI Humanizer

Quilbot is a really popular writing tool that needs no formal introduction. It used to be just a paraphrasing tool, but now it offers an AI humanizer tool feature that does a fairly good job.

I used the word “fairly” because while the content quality it gives is a lot better than WriteHuman and Undetectable AI, it struggles to consistently bypass major AI detectors like GPTZero, Copyleaks, and Turnitin.

If you need a tool that offers more than an AI humanizer, Quilbot is the right option. It offers a grammar checker, a paraphraser, an AI detector, and a plagiarism checker. It is a great all-rounder for students looking for an AI humanizer for essays or for writers who need general editing help.

QuillBot Premium offers competitive, flexible pricing.

Quilbot Pricing

• Annual Plan: Costs $8.33 per month ($99.95 billed every 12 months).
• Semi-Annual Plan: Costs $13.31 per month ($39.95 billed every 3 months).
• Monthly Plan: Costs $19.95.

It is a solid option for turning AI-generated text into human-like writing, but not the strongest for evasion.

Pros of Quilbot Humanizer:

• Excellent content quality and grammar.
• Very established, trustworthy brand.
• Includes a full suite of writing tools.
• Pricing is quite reasonable for the package.

Cons of Quilbot Humanizer:

• Struggles to bypass strict detectors like Turnitin.
• Humanizer is not its primary focus.
• Free ai text humanizer version is very limited.

How to use AI Humanizers to get the best quality

Using AI humanizer tools isn’t magic; you still need a strategy. To get the best results, don’t just paste a huge block of text and hope for the best. Break your content into smaller sections. This helps the AI focus on nuance. Also, always review the output.

Even the best AI humanizer software can make mistakes. Use these tools as a partner to humanize AI, not a replacement for your eyes. Finally, try mixing tools. Use a rewriter, then run it through a grammar checker like Grammarly to polish the human text.

FAQs on the Best AI Humanizer Tool to Bypass AI Detectors

Are AI Humanizer worth it?

Yes, they are worth it if you rely on AI for drafting content. They save time on manual editing and help protect your SEO rankings. By using an AI humanizer, you ensure your work reads naturally and avoids penalties from platforms that flag robotic content.

What is the best AI Humanizer to bypass AI detectors?

Based on my testing, ReHumanize AI is the top choice. It balances cost, quality, and detection evasion perfectly. It serves as an excellent free AI humanizer tool for testing, and the paid plans offer incredible value for bypassing tough detectors like GPTZero and Copyleaks without ruining the text.

How to bypass GPTZero and CopyLeaks?

To bypass these strict detectors, you need to alter sentence variability (perplexity) and structure (burstiness). Simple paraphrasing won’t work.

You must use a dedicated AI humanizer for writers like ReHumanize AI or WalterWrites set to a high humanization level, to restructure the logic while keeping the meaning completely.
