10 Best Tools To Humanize AI Content In 2025

Are you looking for the best ways to humanize your AI content to save time from manually going through and editing your AI-generated content to sound more humane?

I understand some of you will look for a one-off task, while others will look for a more advanced and comprehensive humanizer (e.g., humanize AI content at scale for client work).

In this article, I’ll go over the 10 best tools to humanize your AI content in 2025, going over both free-to-use and advanced tools for different use cases.

What are the factors to consider when evaluating AI content humanizers?

Here are the 3 key factors I’d consider when looking for a tool to help me humanize AI content:

#1: Quality of final output

The reason why you are looking for a way to humanize your content is that you want to level up the quality of your content while making it easier to read and understand.

This is why the quality of the humanization was the #1 thing I took into consideration when considering the tools in this list.

➡️ This includes assessing whether the tool improves the natural flow, sentence variety, and overall reader engagement.

#2: How effective is it to evade AI detectors

As one of the primary purposes of an AI humanizer is to make AI-generated text indistinguishable from human writing, we also want to be able to bypass AI detection tools.

This is why, for this guide, I’ll be running each one of the regenerated texts through an AI detector to see how well they can evade it.

#3: Cost of the generator

Although the bulk of text humanizers are free, I also considered more advanced paid options that can help you humanize content at scale for different clients (e.g., if you’re a marketing agency looking for a best-in-class text humanizer).

What are the 10 best tools to humanize AI content in 2025?

Here are the 10 best AI-powered text humanizers on the market out of the 30+ mini tools I reviewed:

#1: Team-GPT

Team-GPT (that’s us) offers the best place to humanize your AI content in the market because it’s possible to customize an AI model to write like you, collaborate with your team, and refine your best prompt for text humanization with our AI prompt builder.

But if Team-GPT does not have a traditional text humanizer, what makes it ideal for the job in that case?

➡️ Team-GPT offers 3 things that other text converters do not:

• The ability to customize tools like ChatGPT and Claude to humanize content like you.
• A prompt builder, which will help you refine your text humanization prompt.
• Being able to collaborate with your team on content humanization so you can learn from prompts from one another and save your best prompts.

💡 By having better prompts and collaborating with your team, you can better produce human-like content for your clients or your brand in the long run.

Here’s how you can generate humanized text with Team-GPT alongside your team:

Step #1: Build your best content humanization prompt with the Prompt Builder

The way our prompt builder works is that you have to begin by describing your task, such as ‘‘I want to humanize AI content’’ in my case.

After that, our prompt builder will ask you to answer a few follow-up questions about the content that you want to humanize.

For me, these questions were:

• Who is the target audience for this AI-generated content you want to humanize? (e.g., general public, specific industry, experts)
• What tone and style do you want to achieve in the humanized content? (e.g., friendly, professional, humorous, persuasive)
• What kind of AI-generated content are you working with? (e.g., blog post, email, code, report)

As a final output, Team-GPT generated a prompt to use to humanize my content, which provides information about the persona, context, and task:

You can learn more about how you can use our prompt builder by watching this guide on it: How to use the Prompt builder | Team-GPT 

Step #2: Click on ‘’Save & Use’’ and Apply the prompt

After you click on ‘’save and use’’, a new form pops up asking you to fill out your AI content, tone style, and target audience.

Our collaborative AI platform lets you choose the AI model that you want to use for the output, such as ChatGPT’s o3 model.

💡 Pro Tip: This does not have to be an effort from you alone. You can collaborate with your teammates on prompts and save your best prompts.

Here’s the final output that I was provided by Team-GPT after I provided it with my prompt:

ChatGPT’s o3 provided me with a humanized and more playful version of the original article that I provided it with.

But what happens if I were to put this article to an AI detector? I got a 13% likelihood for the content to be AI in QuillBot’s AI detector.

➡️ If you’re not satisfied with the level of output, you can send a follow-up prompt to refine the text further.

Step #3: Turn into a page

Everything you generate inside of Team-GPT (be it an FAQ, an outline or a conclusion) can be turned into a page, similar to Google Docs, to further refine your content.

You just have to click on ‘’Turn to Page’’ on the bottom right of the generated output.

For humanized content, I like to play around with paraphrasing or adding my own unique insights to improve the article’s information gain score.

(Optional) Step #4: Add custom instructions to the AI model to humanize content like you would

If you’d like to step up your AI content humanization further, you can add custom instructions to ChatGPT or the AI model you prefer to use.

Start by clicking on ‘’Custom Instructions’’ on the bottom right of your screen.

From there on, you have to click on ‘’Create instruction.’’

You’ll also notice that you can store these instructions, as my team has done for writing LinkedIn posts.

From there on, you can add your custom instructions, including the type of instructions (e.g., I go with WritingStyle, but there’s also BrandVoice, Persona, and more).

💡 Pro Tip: You can create custom instructions for the different types of content that you want to humanize, such as top-of-the-funnel content or how-to guides.

Team-GPT Pricing

Next Steps: Humanize AI content as you would do it alongside your team in Team-GPT

The right AI-powered content humanizer depends on what kind of output you’re looking for.
