Welcome to my Undetectable AI review.

I’ve been using Undetectable AI for months, chatted with its CEO on business talks through LinkedIn, and tried most, if not all, its features. I even tried it against its competitors—this way, you can say I walk the talk.

In fact, I use this best AI humanizer tool almost daily to check, rewrite, or improve the readability of plain, boring SEO content (yes, even human content can sometimes be flagged as AI).

In this review, I’ll break down all you need to know about Undetectable AI and answer any questions you might have about the tool. That way, you’ll learn what it does and how it can help you so that you can make a wiser choice before investing your precious money into it.

Let’s start the review, and you can then decide.

Undetectable AI Pros

  • Checks for AI detection: There are many AI content detectors in the market, and having to go through all of them is a nightmare. With, you can check the score of the most popular AI detectors in the same dashboard. What a relief!
  • Humanizes AI content: Afraid of being penalized by using AI writing tools? can humanize any text, including with different readability levels.
  • Different human-like styles: The tool lets you humanize your AI-written content using several styles, such as marketing, essay, story, legal, report, and more.
  • Helps you publish more: You can confidently use AI tools to craft your content and humanize it. This will help you get more content out and increase your publishing schedule.
  • Improves readability: Are you a lousy writer? Is English not your primary language? With, you can become a content creator who publishes content that truly sounds engaging and free of errors.
  • Money-back guarantee: If your humanized content doesn’t bypass AI detectors, they’ll refund the cost of the humanization process. There’s nothing to lose.

Undetectable AI Cons

  • No plagiarism checker: Every content creator’s worst nightmare is to plagiarize other creators. Unlike some alternatives, you can’t verify the originality of your text with this tool.
  • No brand voice: While you can access several readability levels, you can’t specify a brand voice. You must still personalize the content to feel more natural to your voice.
  • No formatting: If you copy and paste a blog post with headings and bullet lists, won’t keep your formatting. Instead, it will output plain text without any formatting. So, it’s best to humanize different sections at a time.

Quick Verdict: Is Worth It?

After testing this AI tool with different texts for different purposes, I have to say yes, Undetectable AI is worth the money.

For as little as $5/mo (on a yearly plan that offers 6 months free), you can humanize 10k monthly words and future-proof your website against AI content. You get access to all tools, including the API developer key that you can use in your own applications. Moreover, if, for any reason, the newly humanized content doesn’t bypass AI content detectors, you can request the cost back.

You might think that $5/mo is too expensive. But consider this: those 10k words you get each month can fill a good number of blog posts. Besides, it’s much cheaper than hiring a writer to rewrite your AI-generated text.

Sometimes, you might need to fix grammar, ditch commas, or break up long sentences. But really, these are small things you can easily deal with. Besides, it’s always good to tweak the content and add your personal viewpoints.

However, when you combine the low price that lets you create content indistinguishable from human writing with your skills to generate content, it’s a no-brainer. Plus, you get your humanization cost back if any AI detector flags your content. So, why not give it a try?

Who is Undetectable AI for?

You’ll love Undetectable AI if:

  • You’re a blogger wanting to publish content quickly without being detected as AI-generated content.
  • You’re using AI writing software extensively to craft copy for your website and blog posts and wish to humanize it.
  • You don’t have a budget to hire a human writer and, instead, rely on AI tools to do the job for you.
  • You want to bypass AI writing detection systems while generating engaging content with a human touch.

You won’t love Undetectable AI if:

  • You don’t mind having AI content on your website.
  • You’re a perfectionist and believe that human writers should write all types of content.
  • You believe that AI tools don’t bring the content quality you desire (you couldn’t be further from the truth).

Undetectable AI review - clean interface is a cloud-based software that can check if your content bypasses AI detection tools and humanize it. Consider it as a modern-day paraphraser that passes AI detection.

It’s one of the few tools that can turn any AI-generated text into high-quality content that looks like a human writer wrote it. The main benefit is that it allows you to use AI writing tools and avoid AI detection.

Undetectable AI purposes and styles

Undetectable AI readability levels

And one of the tool’s highlights is the AI content detection likelihood scores.

Undetectable AI detection likelihood featuring many AI detectors

You can confirm on each individual AI writing detection tool’s website, and you’ll see the same results. Fortunately, Undetectable AI displays the scores of the most popular AI detectors on the market, allowing you to save time and do what matters most—crafting great content.

The best part is that, unlike other AI writing tools, you can actually be confident that your AI-generated text will not get marked by multiple AI detectors.

Reasons I Recommend

Imagine using tools like Writesonic or Jasper to write content for your blog. Even if you make some edits, it might (and eventually will) be flagged as AI. Although Google has stated that using AI writing tools isn’t against their guidelines (unless it’s bad quality content written with the sole purpose of manipulating rankings), they can detect if your content is AI or not. Picture this: if AI detectors can, Google can.

Google wants to show trustworthy information that has the intent of satisfying users. Content creators who want to publish human-written content may have a fair advantage over those who generate content with AI tools without any human input. Besides, readers want to feel they’re reading the thoughts of another human being (at least I want)—and that’s something AI writing tools lack.

Although the quality of AI-generated content is improving, especially with GPT-4, it still doesn’t match a human brain that can pivot thoughts and writing styles. If this is something that makes you anxious, Undetectable AI has got you covered.

Google ranks content based on its helpfulness, usefulness, originality, and aspects of what they call EEAT (Expertise, Experience, Authoritativeness, and Trustworthiness). You can’t tick all these boxes with AI writing tools—human expertise is necessary. You can, however, use Undetectable AI to bring a human touch to your content.

What You Might Not Like About Undetectable AI

If you think your content will rank better just because it evades AI detectors like Winston AI, Content at Scale, or, you better think twice.

As I mentioned previously, if your content is not helpful, useful, or original, and doesn’t serve search intent, it doesn’t matter if it’s human or AI—it probably won’t rank.

Having said this, Undetectable AI is not some kind of magic tool that will make your content rank better. There are other aspects to it, including learning how to optimize your content for search engines.

But if you’re already using, there’s something that might turn you down. At least for me, that’s the number one objection that makes me not give Undetectable AI a full 5-star rating—while it can pass even the sharpest AI detectors, it doesn’t include a likelihood score to, known for its ruthless AI detection system.

I’ve used quite often and found it to be very accurate in flagging content written by AI, while others weren’t. However, I must say that Originality AI does have false positives—even truly human writing can sometimes be marked as AI, which is a bummer.

But anyway, only school teachers or those webmasters who are stingy about their published content might turn to a tool like Also, it makes sense why Undetectable AI won’t include it in their detection likelihood—it’s a paid service.

How Does Undetectable AI Work?

This tool has different aspects to it. In this review of, I’ll break down all of them.

1. AI Detection Likelihood

Before you start humanizing your AI content, will give you a score prediction of several detectors. The process is straightforward:

  1. Copy/paste your text into the text box.
  2. Click the “Check for AI” button.
Undetectable AI marketing text example flagged

I questioned ChatGPT about marketing, and the output it gave me is pretty much detected as AI by the top AI detectors.

By combining the strengths of GPTZero, OpenAI, Writer, CrossPlag, CopyLeaks, Sapling, Content at Scale, and ZeroGPT, offers comprehensive detection coverage for AI-generated content.

It’s important to clarify that, a leading paid service in the AI detection field, is not included in this alliance. While focuses on making full use of these eight free detectors to maintain the integrity of original content, pursues its mission independently in the realm of premium detection services.

Unlike detection tools, you won’t get a typical score here. Instead, shows you three types of color codes:

  • Green: 100% human
  • Yellow: 50% human
  • Red: 0% human

Sometimes, the green light doesn’t match the score the individual tool gives exactly. For example, if you get a green light on Content at Scale and if you actually run the content through its AI detector, you might get a 70% human score. That’s why they call it “AI detection likelihood.”

2. Choose Readability and Purpose

As mentioned previously in this review, there are different readability levels and purposes you can choose from. Depending on the type of content you’re humanizing, whether it is business-related, legal stuff, or plain marketing material, you might want to select the appropriate purpose.

Readability basically stands for the complexity level of the humanized text. Do you want a readability at a high school level or a doctorate? Once more, it depends on your content and, most importantly, your target audience.

3. Select Humanization Strength

One crucial feature not present in other reviews is the humanization strength. Right now, it offers three humanization levels:

  • More readable
  • Balanced
  • More human

Choosing the first one will yield a higher quality output regarding readability and grammar. The “more human” approach will need grammar fixing, such as removing or including commas or joining sentences to make it more readable. Nonetheless, all three options will show green lights on all AI detectors.

4. Humanize AI Content

When done with all the above selections, all you have to do is hit the “Humanize” button. In a few seconds, you’ll have fresh content waiting for you.

Using the same example as above, here’s the result of the humanization process.

Undetectable AI humanization strength more human

As explained in the “humanization strength” section, the “more human” approach might have a few bumps, such as missing commas or grammar errors. In this case, I noticed several missing commas and apostrophes. However, these are easily corrected with a grammar tool like Grammarly.

And if you’re unsatisfied, they offer another humanization iteration free of charge.

Undetectable AI Review: Key Features

Final Verdict: Should You Use Undetectable AI?

$5/mo to humanize and create AI-rewritten content is almost a steal! And coupled with some low-cost content generation tools, you can have the perfect set for your writing needs.
