AI detection tools have become increasingly sophisticated.
Platforms like Originality.ai can reliably (and accurately) flag AI-generated content even when different LLMs are used.
This has led to growing interest in the world of ‘AI Humanizers’; tools designed to rewrite AI output in an attempt to sound more human and get past detection.
In this article, we’re focusing on Hire Mia’s AI Humanizer, breaking down what it does, how it works, and whether it is able to get past detection from leading tools or not.
But before we dive straight into the tests, let’s quickly go over what the Hire Mia AI Humanizer is and what it claims to do.
The AI humanizer is a feature within CoSchedule’s Hire Mia suite that claims to take content generated by AI and refine it to make it sound more natural, conversational, and ‘human-like’.
Users paste their content into the tool, it uses AI to rephrase it, and the end result is designed to sound more like it was written by a human (keep reading for test results).
As you’d expect, there’s plenty of demand for a tool that claims to achieve these types of results.
Marketers and writers, for example, want the speed and efficiency that AI output can provide, but without content that feels mechanical or robotic. Not to mention the potential for Google penalties on low-quality AI content.
Content that reads like a human wrote it tends to perform better when it comes to engagement, dwell time, and audience connection, all key elements of good rankings and click-through.
Yes, the Hire Mia AI humanizer is free to use, but that does come with a few caveats.
CoSchedule offers the AI humanizer as a free tool, allowing you to paste your text into it without paying. This is part of a wider suite of free AI writing tools that CoSchedule’s Hire Mia platform offers, as you do need a free account to get started.
On the free plan, you are limited by a certain amount of monthly AI credits, which are needed to humanize content and also use other features, essentially making the tool like a free trial. If you want to use the tool beyond the AI credit limit, you’ll need to upgrade to premium pricing tiers.

To see whether the Hire Mia AI humanizer is actually an effective tool, we put it through our own firsthand testing. We wanted to see for ourselves whether or not the content it produces is detectable by AI detection tools like Originality.ai, Easemate, and ZeroGPT.
Step 1: To do this, we first started by creating content in ChatGPT to use as our baseline, 100% AI-generated content.
Step 2: Then, we pasted our sample text directly into each of the three detection tools listed above, without any changes, so that we could get a baseline AI detection score from each tool.
Step 3: From there, we then took the article and pasted it into the Hire Mia AI humanizer, asking it to produce a new humanized version for us to check.
Step 4: Finally, we took our new Hire Mia AI content and pasted it word-for-word into the three detectors, checking whether it was able to change the baseline score or not.
Original content (AI-generated): 100% Confidence that the text is Likely AI

Hire Mia AI Humanizer Version: 100% Confidence that the text is Likely AI

Original content (AI-generated): 15% AI-generated

Hire Mia AI Humanizer Version: 75% AI-generated

Original content (AI-generated): 9.21% AI-generated

Hire Mia AI Humanizer Version: 9.28% AI-Generated


As the chart shows, the results vary significantly depending on which AI detection tool is used.
When choosing an AI detection tool, it’s essential to review accuracy studies, as different brands offer AI detectors with varying levels of accuracy (Originality.ai has 99% accuracy proven in studies).
The overall takeaway? The Mia AI humanizer fails to reduce detection against industry-leading tools like Originality.ai, which confidently flagged the content as 100% Likely AI.

From our first-hand testing, we found the Hire Mia AI humanizer works by collecting the AI-generated content the user submits, altering the text (with changes such as in flow or wording), in an attempt to produce a version that is more human. However, the Originality.ai AI detector still identified the text as Likely AI with 100% confidence.
From our tests, we found that the Hire Mia AI humanizer was not able to get past AI detection with industry-leading tools like Originality.ai; its humanized text was still detected as 100% Likely AI.

When comparing Rytr to other AI content generation tools, it won’t take long for you to realize that it lacks almost all the features that its competitors do. As a result, it certainly isn’t the best option for marketing or AI experts looking for a detailed tool with plenty of additional capabilities. However, while Rytr’s offering is very basic, what it does do, it does very well. It is a solid AI generation tool, and the addition of an image generation tool is a nice touch. If you are new to AI content generation, Rytr can be a solid jumping-off point for beginners, but quickly you will realize the capabilities of other tools and will likely choose to move on.
