If you’re looking for the best AI humanizer tools to help you bypass AI detectors, this list will provide you with the best picks out there that can actually transform your AI-generated text into undetectable AI text.
The evaluation involved various AI detection tools, with Originality.ai—a paid service renowned for its robustness and difficulty to deceive—being employed for the most stringent test. This means that if the content passes Originaly.ai, it passes all others.
The last thing you want is to throw out money on an AI humanizer tool just to figure out later your content has been detected as AI.
Choosing one of these tools will ensure you can continue to use your favorite AI writing tool without being detected.
Let’s move on!
How I Tested the Best AI Humanizer Tools
Humanizing AI content is still a relatively recent trend in the industry. As a matter of fact, it’s also funny to see AI tricking AI!
I scoured the internet to find the tools that could humanize AI-generated content, and from all those I found, only the ones that passed my criteria ended up featuring on this list. It’s simple—it must pass Originality.ai, the most fierce AI detector you can find.
Originality.ai is a paid service, and as such, not all tools have access to it. But even those tools that claim to bypass it, not all of them are authentic (at least 100% of the time).
I also tested tools like GPTinf and Huxli to find out that they were flagged 100% written by AI. Although they’re considered AI humanizer tools, and while they certainly may pass other detectors, I didn’t include them on this list.
What are the Best AI Humanizer Tools?
1. Undetectable AI
Best overall.
Key Features
- It cross-checks between several AI detectors before you humanize the content.
- The software’s algorithms undergo regular updates to keep pace with the latest AI detection systems.
- Includes several options for readability and purpose.
- It offers different human strength levels.
Pros
- Offers excellent value for money, allowing you to save 50% on yearly plans.
- You can select from several tones for the humanization process.
- Access all the previous humanization documents inside your dashboard.
Cons
- At times, the tool may experience glitches, resulting in blank text.
Undetectable AI Overview
Undetectable.ai is, without a doubt, one of the best AI humanizers out there. Apart from being a pioneer in the field, they offer something other humanizers don’t: different output styles.
Whether you’re publishing a report, marketing content, a piece of journalism, a cover letter, legal material, or others, the tool’s AI model can transform your AI content into high-quality writing that follows those styles.
Other tools also don’t display a likelihood score like Undetectable AI does. Instead of checking all AI detectors manually, you can cross-check the most popular and free ones right inside the dashboard.
It’s no wonder they have been featured on CBS, Fox, NBC, BuzzFeed, and other prestigious outlets. Besides, they offer an enticing pricing plan, entitling you to get 6 months for free when you subscribe annually.
You can read more about the tool in my in-depth Undetectable.ai review.
I Tested Undetectable AI
I asked ChatGPT to write about 120 words on the topic “How digital nomads stay mentally healthy.” I cross-checked the AI content detectors Undetectable AI provides, and this was the result.
Just to make sure the content is really flagged as AI, I also passed it through Originality.ai, the most challenging detector on the market.
Yes, ChatGPT content is definitely flagged as being AI-generated.
Putting Undetectable AI to the test, I ran the content through the highest humanization level it offers.
And here’s the output.
Now the test begins! Will Originality.ai pass this content as human?
As you can see, using the latest AI detection model (2.0), it came out as 98% human content. If it passes Originality.ai, it passes all AI detectors.
It’s important to note that there were some grammar elements to fix, like adding commas, hyphens, and even combining sentences. Also, make sure you edit the text in order to give your personal viewpoints, helping you make more meaningful contact with the reader.
2. HideMyAI
Best for conversational content.
Key Features
- Cross-checks the most popular AI detectors, including Originality.ai.
- You can select the type of writing, readability level, and perspective.
- Allows you to upload documents in TXT or DOCX to humanize AI written content in bulk.
- Supports English, Spanish, Russian, and French.
Pros
- Match the content to your desired style.
- Great for multilingual purposes.
- Besides avoiding AI detection, it makes the content more humanlike and conversational.
Cons
- You have to fix grammar errors and remove slang words if you wish a more polished text.
HideMyAI Overview
HideMyAI is an outstanding AI humanizer tool that helps you create truly undetectable AI content that bypasses all AI content detection tools. Furthermore, it displays the detection probability of Originality.ai (the only tool that does it), Turnitin, CopyLeaks, ZeroGPT, and Content at Scale.
As one of the best Undetectable.ai alternatives, it offers a similar interface but with more advanced AI options, such as matching the perspective of the text to the first, second, or third person.
Moreover, if you generate content in Spanish, Russian, or French, HideMyAI has you covered. As the only undetectable AI tool to provide multilingual support, you can humanize your AI content to reach a global audience.
And lastly, you can import documents in bulk for simultaneous AI humanization.
I Tested HideMyAI
Using the same sample provided by ChatGPT, I put HideMyAI to the test.
For starters, HideMyAI language skills are not as professional as Undetectable AI’s. For instance, you see slang words like “gotta” and others. It also adds two spaces after each period. It’s normal to see some commas and apostrophes missing.
However, that’s not a problem. Originality.ai flagged it as 85% human content, even after fixing those aspects and replacing the slang words with more appropriate ones.
If the content score had beaten Undetectable AI’s, this tool would be at the top of the list.
3. Netus AI
Best for originality and creativeness.
Key Features
- An all-in-one tool with a paraphraser, summarizer, AI detector, and AI bypasser.
- All content is plagiarism-free.
- It offers multiple algorithms for bypassing AI detectors.
Pros
- It provides a fast AI check before you humanize your content.
- You can fine-tune the humanization process.
- There’s no need for extra tools when it comes to plagiarism checker.
Cons
- The interface is a bit clunky.
- Too many algorithm choices can overwhelm you.
Netus AI Overview
Netus AI is a paraphraser tool that not only rewrites your text but humanizes it using AI. Besides beating AI detectors, it also bypasses plagiarism checkers, so you can rest assured your content is original.
As one of the best AI tools for humanized content, you can check for AI within the dashboard, although they don’t give you any clue about which detector was flagged.
One thing I like about Netus over most other tools on this list of the best AI humanizers is the creativity of the output. It really strives to give a more creative spin to your text, including analogies, conversational tones, and even humor.
I Tested Netus AI
Netus AI may seem to have a more cluttered interface, especially the AI Bypasser feature. Besides having Detector V1 and Detector V2, it currently offers 50 bypassed algorithms. According to them, V30 to V50 works well for all AI detectors, including Originality.ai. Let’s see if they’re being truthful.
I pasted the original text from ChatGPT on the left and checked it for AI within the platform. Netus clearly flagged the orange section as being AI-generated.
On the AI Bypasser window, I first chose the Bypasser V50 algorithm, and Originalty.ai flagged it as 100% AI. However, after choosing the V46, it returned a 96% human score.
Despite the V50 being detected by Originality.ai, I ran the same output on different detectors, and all of them returned a 100% human score. This is not pure science, and you’ll have to do tests on your side to achieve your desired result.
4. Chat by Copy.ai
Best for high-quality content generation.
Key Features
- Ask the software what you want, including generating content that avoids AI detectors.
- Analyze websites for detailed information.
- Get factual data from Google searches.
- Unlimited content generation.
Pros
- It always uses the latest AI models, so you always get the finest quality.
- Once you find the best prompt, you can keep it in your favorites to use later.
- Highly conversational tool.
Cons
- It doesn’t check for plagiarism or AI detection.
Chat by Copy.ai Overview
You might be wondering why Copy.ai is in this roundup review. In fact, Copy.ai is one of the best free AI writing tools with a lifetime free plan. But that’s not all.
Unlike other AI chats that can retrieve information about Google searches, Chat by Copy.ai is the only AI writer that can analyze webpages, YouTube videos, and websites in general to bring you detailed information about them.
It also uses the latest AI technology, GPT-4, for generating AI-written content, improving the quality of your material.
I Tested Copy.ai
Because it is a chat tool, you can ask it whatever you want. In this case, I asked Copy.ai to humanize the content for me. Here’s a screenshot that depicts it.
Just by looking at the text, I’d tell it would be flagged as AI—and it was! But that’s not the end of it.
Because we’re dealing with an AI chat, I can refine my question or simply follow up with it, saying it doesn’t pass AI detectors.
And here’s the magic of this AI tool. Look at what it answered back.
After pasting this new content into Originality.ai, it flagged it as being 54% original.
Not bad for an AI writing tool. You can’t get this with any other AI writer, and apart from that, it’s one of the reasons I highly recommend Copy.ai to anyone interested in generating written content with artificial intelligence.
Besides, you can input your brand voice and be very specific about it for every text generation the software does. This is vital if you want genuine content that has the potential to bypass AI detectors.
And if it still flags as AI content, keep refining your prompts and brand voice. Eventually, you’ll get there. And don’t worry—the premium plan offers unlimited words.
5. WordAI
Best rewriter.
Key Features
- Create 1,000 variations simultaneously while maintaining originality.
- Rewrite multiple documents simultaneously.
- Make your content more human.
- Protect words, titles, URLs, and quotes from being rewritten.
Pros
- It lets you repurpose content while maintaining originality.
- Easy-to-use interface.
- You can integrate with Article Forge, an undetectable AI writing tool, to create several variations of your articles.
Cons
- The AI humanization may not prove to be truly optimal.
WordAI Overview
WordAI is a premium rewriter tool that lets you create unlimited variations of your content. If you want to repurpose your content on multiple platforms without plagiarizing yourself, this is your tool.
It also includes an “Avoid AI Detection” tool that makes your AI-generated content more human. And this is key: “more human,” not “human.” You’ll see why in the testing section below.
Unlike other tools like Undetectable.ai, WordAI (review) transforms your content with almost no grammar errors. It also puts the changes in meaning and structure to a minimum. Apart from that, you can choose two levels to humanize writing: “change less” and “change more.” The “change more” feature helps more difficult content bypass AI content detectors.
I Tested WordAI
Using the same ChatGPT answer about the digital nomads, here’s what WordAI created.
And here’s the result from Originality.ai.
That’s disappointing!
However, other AI detectors flagged the content as being truly human. Here’s the result with Content at Scale’s AI detector.
And here’s with ZeroGPT.
And Writer.com.
So, why do I include WordAI in this article? Well, AI content detectors are not perfect, and even the best tools have false positives. In fact, 1.56% of the time, human-written content is accused of being AI-written.
Here is some critical information to keep in mind. According to Originaliy.ai,
When any amount of AI touches the content, it can cause the entire article to be flagged as AI.
AI Outline, Human Written and heavily AI Edited = AI-Generated Text.
—Jonathan Gillham, CEO of Originality.ai
Ultimately, no AI detection tool can conclusively prove that your content was definitely generated by AI.
Best AI Tools to Humanize AI Content: Final Verdict
If you want to turn flagged AI content into high-quality original content, these best AI humanizer tools will cover you. However, it’s important to remember that AI technology is constantly evolving, and what stands as truth today might not hold the same certainty by tomorrow.
In light of this, learning how to humanize AI content is crucial, including not only using tools like the ones above but also your own human creativity.
But if you’re lazy right now, I highly recommend going with Undetectable AI or HideMyAI for similar features and pricing. On the other hand, if you require an outstanding AI writing tool, go with Chat by Copy.ai.
