3 Best AI Humanizers to Humanize AI Text (in 2024)

In this blog post, I’ll discuss the 3 best AI Humanizers I found that are producing good quality content.  

If you’re working with AI-generated content, an AI humanizer can help to humanize AI text and to bypass AI detection. This can lead to a decreased risk of being punished by Google and increase your chance of ranking a blog article or a website in the top pages of Google. 

AI humanizers can help with getting beyond AI detection, but it’s important that they do so without sacrificing the text’s quality. While using too many unusual terms or reducing the quality of the text may help avoid discovery, the result may be strange and unappealing content.

I’ve tested 20 AI Humanizers and summarized the results of the 3 best AI Humanizers I found that produce good-quality content.

How I Tested The Best AI Humanizers

I’ve tested over 20 tools to find the best AI Humanizers and to be honest, I was shocked by how much some AI Humanizers were damaging texts. Some tools included weird wording, blew up the text and others even changed the meaning of sentences.  

Rephrasing AI-generated texts and making AI content “undetectable” but at the same time good to read is a huge challenge. From the 20+ AI Humanizers I tested, just 3 stood out, that had rephrased the texts I had given them and still made them sound good.

What Are The Best AI Humanizers?

Discover my picks of the 3 best AI text humanizers to evade AI detection while maintaining the quality and engagement of the content.

1. Undetectable AI

Starts from $5/month (if billed yearly) for 10,000 words.

Undetectable AI was the only tool that created truly undetectable AI content. This tool can turn AI-generated texts into well-written content that bypasses most AI detection tools.

Undetectable AI offers options to adapt the content according to a certain style or writing purpose. For readability, there is an option to choose between ‘university’, ‘high school’, ‘journalist’ or ‘marketing’. As for the writing purpose, there are options available like ‘general writing’, ‘cover letter’, or ‘essay’. 

Key Features:

• Passes AI detectors
• Built-in AI detector
• High-quality, readable content
• Multiple readability options (e.g. ‘University’, ‘Journalist’, ‘Marketing’)
• Multiple purpose options (e.g. ‘General Writing’, ‘Essay’, ‘Marketing’, ‘Story’, ‘Cover Letter’)
• API compatible
• Option to make a text ‘more readable’, ‘balanced’, or ‘more human’
• All humanized content is saved and can be accessed under the documents tab

My Experience: 

Undetectable AI was easy to use and the writing style was simple to adjust by choosing the writing mode or purpose of the text.

It produced a good quality text and the fact that it saves your original input as well as the rephrased and humanized output (in the paid versions) is really helpful when you’re working with a lot of AI content on a regular basis.

Results:

Here is an example of a AI-generated text I posted and the ‘humanized’ version which Undetectable AI generated:

• AI-Detection (Quillbot): 100% Human
• AI-Detection (GTPZero): 53% Human, 47% AI-generated

What I like:

• Creates good texts. They sound natural and well-rephrased.
• Passes well-known AI detectors like GPTZero and Quillbot as mostly human.
• Offers a money back guarantee.

What I don’t like:

• Not all AI detectors validate the text as 100% human.
• Some sentences still need manual work to sound really human-like and well written.

Pricing:

• Free Trial
• Paid Monthly – $14.99/month: Starting from 15.000 words / month – passes most AI Detectors, API compatible
• Paid Yearly – $5.00/month: Starting from 10.000 words / month – same features
• For Business – Custom Pricing: Non-expiring-credits and priority support

2. Quillbot

Unlimited words for $8.33/month (if billed yearly, otherwise $13.33 if semiannual or $19.95 if paid monthly).

Quillbot is one of the best AI Humanizers I found with a lot of features and flexibility.

After rephrasing it allows you to exchange single words or sentences and offers you many examples for synonyms or alternative phrasings when you click on a word or sentence.

It also offers a free AI detection tool where you can post the created content to see which parts you need to rework and which ones are recognized as 100% human.

Key Features:

• Unlimited words in Paraphraser
• Unlimited Custom and 8 predefined modes
• Full use of Synonym Slider
• Unlimited Freeze Words
• 6,000 words in Summarizer
• Plagiarism Checker (100 pages/month)
• Create unique summaries using custom instructions
• Recommendations
• Compare Modes
• Tone insights
• Paraphraser History
• Browser Extensions Available
• Different Languages Available

My Experience: 

This tool is my Top Pick due to its flexibility and availability of synonyms that allows me to exchange certain words or parts of the content it produced.

It reshapes the text to form a new structure and paraphrases the content to create something new without losing the original intent.

I really loved the visibility of the changes it showed as well as the flexibility and the way I could work on the text after rephrasing it. It allowed me to exchange single words or sentences and offered a lot of synonyms or alternative phrasings when I clicked on a word or sentence.

It also has a free AI detection tool which allows me to validate the generated content. It did detect some parts as human and some as “AI generated and rephrased” but I could then go back to the text, exchange some words for the synonyms Quillbot offered and Voilá, I got a text which was evaluated as ‘100% human’.

Results:

Here is an example of a AI-generated text and the ‘humanized’ version Quillbot has generated:

• AI-Detection (Quillbot): 100% AI-generated and paraphrased
• AI-Detection (GTPZero): 9% Human, 91% AI-generated

What I like:

• Good Text Quality
• Cost-Effective
• Offers Unlimited Words
• Shows Rephrasing Options & Marks Text Changes
• Best User Interface & Customization Options
• Also Custom Tone as Rephrasing Mode Available
• More Tools (also Grammar Checker, Summarizer, Translator)

What I don’t like:

• Text was detected as mainly AI-generated

Pricing:

• Free Trial
• Paid Monthly – $19.95/month: Unlimited words, Plagiarism Checker, different modes and a custom mode, synonym slider
• Paid Semi-Annually – $13.33/month: same features
• Paid Annually – $8.33/month: same features

3. Humanize AI

Free Tool

Humanize AI is an AI humanizer tool that converts AI text to human-like text. It has an easy to use Interface and offers unlimited rephrasings for free.

Key Features:

• Free
• Easy-to-Use Interface
• No Registration Hassles
• Unlimited Access
• Contextual Intelligence
• Sentiment Analysis

My Experience: 

Humanize AI was the only free tool which I thought was worth adding to the list of best AI humanizers. It produced astonishing good text quality considering it to be a completely free tool.

It’s easy to use and can generate good ideas for rephrasing text. The fact that both AI detectors evaluated the text as 100% AI-generated, shows that it’s not really a reliable tool if you want to produce human-like content without rewriting some content.

Results:

Here is an example of a AI-generated text and the ‘humanized’ version Humanize AI has generated:

• AI-Detection (Quillbot): 100% AI-generated
• AI-Detection (GTPZero): 100% AI-generated

What I like:

• Produces good quality text (also preserves meaning and context of the content )
• Easy to Use Interface
• It’s free

What I don’t like:

• Most of the texts were recognized as generated by AI
• Doesn’t have a lot of additional functions
• No mode choices, so impossible to add instructions or to choose different writing styles or text intents
• Doesn’t have an option to save texts

Pricing:

With Humanize AI you can humanize AI text for free.

Summary Of The Best AI Humanizers

I hope my discussion of the 3 Best AI Humanizers can help you to produce more content in less time and to make your AI-generated content less detectable, while keeping a good text quality.

Even though I was really amazed by the produced quality of the texts I know that it will stay a challenge for many AI Humanizers to keep up with improvements in AI detection. So I treat all AI generated content as a draft and try to add my own spins on texts.

There will surely come a time when AI writers will be better trained and able to write content that sounds as human as you or a professional copywriter would write. But we’re not there yet. I haven’t seen an AI tool, writing as beautifully and creatively as a human being.

And still, learning how to use an AI content writer can give you a huge advantage when creating content.
