How to Bypass GPTZero and Copyleaks: Bypass GPTZero AI Detection

Quick answer: The best AI humanizer to bypass GPTZero and Copyleaks AI detectors is ReHumanize AI. How true is this? You’ll find out in this review.

Have you ever spent hours creating content only to have it flagged by a detection tool like GPTZero or Copyleaks? You’re not alone. The good news is, there’s a solution to this problem: AI humanizers. But first, let’s take a look at why we need them.

As content generation has become increasingly important for businesses, educational institutions, and individuals, use AI detectors to determine whether a human or ChatGPT wrote a piece of content. While these detectors aren’t foolproof (they can produce false positives), they do pose a challenge for users.

It’s a problem that has many different aspects:

• As a student, you could be accused of cheating.
• Freelancers and agencies run the risk of upsetting clients and damaging their reputation.
• If you’re a business owner, your website could lose its search engine rankings.

So, it’s important to find a way around this issue—which is why you’re reading this right now.

In this post, we’ll take a look at the five best AI humanizers that can bypass GPTZero and Copyleaks detectors. I’ll walk you through their features, prices (where applicable), pros, and drawbacks. We’ll also reveal the best tool out there.

If you’re tired of seeing ‘this content was AI-generated’ messages whenever you use an AI detector on your work, keep reading to learn how to bypass GPTZero and Copyleaks to ensure your content remains undetectable.

Best AI Humanizer to Bypass Copyleaks and GPTZero at a Glance

If you’re in a hurry and want to bypass Copyleaks AI checker or ensure your writing isn’t flagged as AI on GPTZero, you need a reliable AI humanizer. Below are the top picks, reviewed head-to-head so you can make the best decision before subscribing to any one of them.

How I Vetted the Best AI Humanizer to Bypass GPTZero and Copyleaks

I wanted to see for myself which ones were truly effective. So, I decided to put them to the test. My first step was to create two 400-word articles using Google’s AI, Gemini. Since these were typical AI-generated articles, they would undoubtedly be flagged as AI content by any detection software.

I then ran the AI-generated content through the five humanizers I’ve reviewed here. My aim was simple: see if they could help me bypass AI detection. To find out, I checked the results against Copyleaks and GPTZero— the two leading AI detectors. If an AI humanizer can bypass GPTZero, it should be able to do the same with other detectors out there.

But I did not just want to see if the humanizers could help me bypass AI detection; I also wanted to see if they could retain the overall quality of the content. So, after running the content through the humanizers, I read it to see if it sounded natural or robotic in any way.

Some of the AI humanizers here offered an AI detector alongside its humanizer. However, they often give false negatives— indicating that the content is not AI-generated when it actually is. The only exception to this was WalterWrites AI, which uses GPTZero’s official API to detect AI content. 

After testing all five humanizers, one stood out from the rest: ReHumanize AI. Not only did it bypass GPTZero and Copyleaks better than any other humanizer, but it also retains the overall quality of the content. 

Plus, it comes with an advanced grammar checker (like Grammarly) and a readability tool called ReadBreeze — meaning you get two extra useful tools for free when you subscribe to any plan.

In this blog, I am going to show you how to bypass GPTZero and Copyleaks using five different tools in 2026. Whether you are a student, freelancer, blogger, or business owner, these tools will help you create high-quality content that looks like a human wrote it.

How to Bypass GPTZero and Copyleaks AI Detection: 5 Best Tools in 2026

If you are ready to learn how to bypass AI detectors and make AI text undetectable, these are the tools you need to know about.

1. ReHumanize AI

This is an AI humanizer that consistently passed Copyleaks and GPTZero AI detection. It’s a tool that does exactly what it claims. It is reliable, easy to use and generates quality results every time.

When testing ReHumanize AI, I threw everything at it, and it handled it all with ease! Not only did it bypass GPTZero and Copyleaks, but it also bypassed ZeroGPT, Quillbot AI Detector and Turnitin!

Regardless of which AI detector you use, ReHumanize AI will help you bypass detection every single time! You won’t have to worry about being caught out by an AI detector when using ReHumanize AI because this tool has been specifically designed to help users bypass them!

SEO Preservation

For web writers, ReHumanize AI offers SEO preservation. This means that when using this tool to make your content more human and less detectable by AI, it will retain your important keywords. Many AI humanizers fail at this, messing up keywords and ruining your SEO – how you rank on Google. Not only does ReHumanize AI help you bypass Copyleaks, but it does so without sacrificing your SEO.

Content Quality Maintenance

As I have experienced with many AI bypassing tools, their performance in terms of content quality is quite disappointing. There are lots of incomplete sentences, strange sentence structures, and broken phrases. On the other hand, “ReHumanize AI” produces well-structured, grammatically correct, and natural-looking content. So, if you want to create quality content, then “ReHumanize AI” ticks all the boxes.

Free Rewrite Loop

Sometimes, it takes a few attempts to get the best output (content) from a humanizer. Most bypass tools will take more of your word allotment even when you run the same content through their humanizer multiple times. 

This means that you will end up using up your monthly word count very quickly. This is not something that you will have to worry about when using ReHumanize AI because they don’t charge you extra for running your content through their system multiple times.

Advanced Grammar Checker and Readability Tool

ReHumanize AI also provides an advanced grammar checker and readability checker (ReadBreeze) with its paid plans. You don’t have to pay for these tools separately, which is a great deal for freelance content writers. You get to convert your AI-generated content into human-like content that is undetectable at an affordable price.

Here is a screenshot of what the grammar checker looks like:

ReHumanize AI Pricing

The pricing of ReHumanize AI is quite affordable, and anyone can afford it. The starter plan is available for just $9, which provides a 25000-word limit. The standard plan costs $18, which provides a 50000-word limit. Most freelancers prefer this plan. 

The pro plan costs $30 and provides an 85000-word limit. Although ReHumanize AI doesn’t provide any unlimited word count plan, the 85000-word limit is more than enough for most content creators.

You will get a 40% discount on all yearly plans. There is a free forever plan that allows you to humanize 700 words every month. This free plan allows you to test the tool before you make a decision if it’s worth a subscription. 

A lot of the humanizers we’ve reviewed here are very limited in their free plans.

• WalterWrites AI: Free 300-word trial, not a monthly free plan 
• Humanize AI: 1500 words to try out the tool with no sign-up required, but not a forever-free monthly plan
• BypassGPT.ai: You get just 200 words to try out the tool when you sign up
• Undetectable AI: 3-day free trial, but you’ll have to input your card details 

You will get three different writing styles (casual, conversational, and formal) with this plan. The editor of ReHumanize AI is quite simple and easy to use.

Pros of ReHumanize AI:

• Bypasses GPTZero, Copyleaks and Originality.ai with ease and consistently 
• Has an advanced Grammar Checker and Readability checker 
• SEO preservation to keep your keywords intact
• Free rewrite loop 
• Authentic content with a human touch
• Very affordable paid plans
• Simple user interface with many writing styles

Cons of ReHumanize AI:

• No unlimited word count plan
• Doesn’t have an AI detector

2. WalterWrites AI

If you want your content to appear more human and natural, try WalterWrites AI. Its simple editor is divided into two sections: you paste your AI content on the left side, and the tool will show you its humanized version on the right side. There are five readability levels available, and each one is geared towards a specific audience.

You have 11 different purposes to choose from, which means you can customize the output to suit your needs.  WalterWrites also offers three levels of detection bypassing: simple, standard, and enhanced.

When using WalterWrites AI, you’ll notice that the enhanced mode produces lower-quality content when compared to the simple and standard modes. If you want quality content, you’d have to stick with the simple mode.

Another issue is that it sometimes struggles to bypass GPTZero depending on the type of content you’re working on. However, it does really well with other detectors like ZeroGPT, Copyleaks, Winston AI and Quilbot. 

One standout feature of the tool I really like is the AI detector. WalterWrites includes its own content detector, which uses the official GPTZero API, to check whether the content is AI-written. It’s the only tool on this list that offers a reliable AI detector. 

WalterWrites AI Pricing

• Starter plan $12 (30,000 words per month)
• Pro plan $23 (70,000 words per month)
• Unlimited plan $47 (per month)

The annual plans offer a discount of 45%.

Pros of WalterWrites AI

• The unlimited plan is great for heavy users.
• The content detector works very well.
• There are many readability levels and purposes.
• The side-by-side editor is very user-friendly.
• Simple mode creates better content than enhanced.

Cons of WalterWrites AI

• Enhanced mode creates poor content.
• Struggles to bypass GPTZero AI detector.
• No free rewrite loop consumes credits fast.
• It doesn’t have a grammar checker.

3. Humanize AI

Humanize AI is one more tool that helps you make your AI content look more human. The fact that there are so many controls (free, standard, academic, simple, flowing, informal, formal, expand, shorten, and custom) makes this an excellent choice if you want to experiment with different tones or ways of bypassing AI content detectors.

When you sign up for a free account, you get 1500 words that you can use to test the tool. Keep in mind that this is not a monthly allowance; once you use up your 1500 words, the free account will be unusable until you buy a plan.

On the right side of the interface, there is a button labeled “ultra run.” Humanize AI claims that this feature will allow your content to bypass any AI content detection software.

They also provide an AI detector with the text converter, and I wanted to see how good it was, so I compared it with other popular AI detectors like GPTZero and Copyleaks. Unfortunately, it failed to identify AI-generated text created by Gemini as such, which could cause problems if you rely on it.

Humanize AI Pricing

Humanize AI has three paid plans: Lite, Standard and Pro.

• Lite Plan: $19 per month for 20,000 words.
• Standard Plan: $29 per month for 50,000 words.
• Pro Plan: $79 per month for 150,000 words.

While you can pay for the service, it’s more expensive than ReHumanize AI if you want an easy way around Copyleaks.

4. BypassGPT

If you’re looking for another way around Copyleaks and GPTZero, you might want to check out BypassGPT. This tool markets itself as a “humanizer,” but it also doubles up as an AI detector. The service offers three modes of writing: Fast, Creative and Enhanced.

During my test run, I found that Enhanced mode created a lot of strange and awkward sentences that made absolutely no sense. The impression I got was that it was trying too hard to bypass detection and thus ended up producing unnatural-sounding text. It’s free plan only allows for 150 words per month, which is too little in my opinion.

BypassGPT Pricing

Their pricing structure is quite simple. They have three paid plans:

• Basic Plan: $12 per month for 5,000 words.
• Pro Plan: $35 per month for 30,000 words.
• Unlimited Plan: $39 per month for unlimited words.

By looking at their pricing, it’s obvious that they’re trying to push users into buying their unlimited plan since the lower-priced plans don’t offer much value at all.

I also took their AI detector for a test run, but I wouldn’t recommend using it because it failed to detect AI content created by Gemini as AI content.

5. Undetectable AI

Undetectable. ai is not just an AI humanizer. It’s also an AI detector, an AI essay writer and an AI SEO writer. We were mainly interested in seeing if it could help us bypass Copyleaks & GPTZero, though, so that’s what we tested.

New users at AI humanizer are given a 3-day free trial to try out the service. In order to start the free trial, users must enter their credit card information. After the three-day period is over, the company will automatically charge the user’s credit card for the amount due for the selected plan.

This means that AI humanizer does not have a forever-free plan, and it’s impossible to bypass GPTZero with free methods without a credit card on this site.

We found content quality to be one of the consistent issues with the tool. At times, it comes up with hallucinations and really weak grammar! Within the editor is a setting called “humanization,” which has three humanizer models: Basic, Stealth, and Undetectable.

I did notice that choosing the Stealth or Undetectable model means you have to sacrifice quality for the most part. The tool tries to make sentences complicated enough so they’ll pass detectors, but the sentences often end up being broken or nonsensical. 

You can also select readability level, purpose, and human level all from within settings. So, does the tool pass detectors? Yes! But the majority of the time (especially with the Stealth and Undetectable models), the content makes no sense. It may say “100% human” on the score, but you’ll barely be able to read what you wrote.

Undetectable AI Pricing

Undetectable AI is one of the most expensive undetectable AI writing tools on the market. Their plans are as follows: 20,000 words for $19 per month, 35,000 words for $31 per month, 50,000 words for $42 per month.

In fact, when compared to other humanizers on our list, undetectable AI is the most expensive option for those who need to pay: $64 for 80,000 words. For comparison’s sake, ReHumanize AI charges $30 for 85,000 words (or $47 for unlimited words with WalterWrites AI).

Do we recommend this tool? Not really. It’s got a lot of drawbacks, but people seem to like it regardless— probably because of a lot of marketing.

Pros:

• Offers an all-in-one suite with essay and SEO writers.
• Technically capable of passing detectors on high settings.

Cons:

• Stealth mode ruins content quality.
• Very expensive compared to competitors.
• Requires a credit card for trial.
• Prone to hallucinations and grammatical errors.
• No forever free plan.
• No free rewrite loop

Conclusion

It’s not just about getting around Copyleaks or GPTZero AI content checker; it’s about making sure what you write is valuable. In other words: don’t sacrifice quality for the sake of getting a better human score!

That being said, if your goal is to consistently bypass Copyleaks and GPTZero while keeping your content quality great (in terms of editing time, at least), there’s one tool we’d recommend above all others: ReHumanize AI.

Undetectable AI, Humanize AI and BypassGPT don’t seem to do a good job at producing quality content and are a more expensive option in terms of pricing. From our head-to-head comparison, ReHumanize AI and WalterWrites AI provide the best value for less money.

Walter AI does a good job like ReHumanize, but it struggles to bypass GPTZero and even sometimes Copyleaks consistently.

You might have to humanise a specific piece of content several times before it bypasses Copyleaks and GPTZero, and with the fact that there is no free rewrite loop, it quickly eats into your allocated word limit. The AI detector offers checks all the boxes as a reliable tool because it uses the GPTZero API.

With ReHumanize AI, you bypass all major AI detectors, keep content quality, free rewrite loops, and don’t have to pay separately for a grammar checker, all at a fraction of the price compared to other tools out there.

Frequently Asked Questions on How to Bypass GPTZero and Copyleaks

1. How to make AI-generated text undetectable by AI detectors?

If you want your AI content checker results to say “human,” simply reworking your text may not do the trick. You’ll need to tinker with something called “burstiness” and “perplexity”: how predictable (or not) your writing is. Fortunately for you, we’ve found a way around this problem: Use ReHumanize AI content editing software!

2. How to bypass GPTZero AI detector?

It’s worth remembering that simply rephrasing your text may not be enough to get past an AI content checker like GPTZero— they can usually tell when you’re up to this trick by looking at the “syntax trees” (i.e., structure) of your sentences. What they’re really looking for is logical flow. In other words: Does your content read like something a human would have written? ReHumanize AI does a great job of altering logical flow— so if you’re looking for an easy way to bypass GPTZero’s AI content checker, this might be just what you need.

3. How to bypass Copyleaks AI detector?

You probably won’t get very far using simple paraphrasing tools to beat Copyleaks AI content checker: It’s very good at picking up changes in syntax (i.e., how you’ve reworded your sentences). This will ensure there are plenty of logical inconsistencies (from an AI’s perspective) in your text, giving you a much better chance of passing Copyleaks’ AI content checker test! The best AI humanizer to bypass Copyleaks AI detector is ReHumanize AI or Walter AI.

4. What is the best AI humanizer to bypass GPTZero?

If you want something fast, cheap and effective that will also help boost your SEO rankings at the same time, look no further than ReHumanize AI. In our tests, this tool consistently achieved human detection scores of 100% while keeping language clear and free from spelling and grammar mistakes. It’s also great for rewording content without losing SEO keywords— a common problem when editing posts manually or with cheaper paraphrasing tools.

5. What is the best AI content detector?

You’ve probably heard people say GPTZero is the best AI content checker around— and they are right. It has an incredibly low false-positive rate (meaning it doesn’t mistake human writing for AI-generated content very often). Copyleaks comes close behind— it’s known for its strict enterprise-level scans, so if anything slips past Copyleaks AI detector, there’s a good chance GPTZero will pick up on it!
