AI humanizers can make AI-written text sound more natural. Super Humanizer and Clever AI Humanizer are two of the most popular ones nowadays. Both of these tools deliver different quality results and are claimed to be better than each other.
To see what really happens, we are going to test Clever AI Humanizer and Super Humanizer with the same type of AI-written content.
Our goal was simple. We want to see which tool can give us better human-like text without making the content hard to read.
So, let’s explore both of these AI humanizers in depth.
Both Super Humanizer and Clever Humanizer are free to use with no daily limits. However, the word count limits per run vary. Super Humanizer is one step ahead, as it now also offers paid plans that offer extra quality, formatting-retaining features, and customized output options.
The table below represents what both of these AI humanizers are offering at the time we are writing this article.
| Feature | Super Humanizer | Clever AI Humanizer |
| Free usage | Yes | Yes |
| Daily limits | None | None |
| Words per run | 1200 free, 5000 with plans | 3000 (free) |
| Humanizing modes | Lite & Ultra | Normal |
| Output quality | Good | Average |
| SEO content | Yes | Not recommended |
| Content readability | Improves | Affected |
| Shows history | Yes | No |
| Text cleaning settings | Yes | No |
| Purpose-based humanization | Yes | No |
| Speed | Instant | Slow |
| Overall Pick | Good to humanize AI text | Can humanize but requires careful review |
Both tools have a simple setup. You paste your text, choose the required option, and get a rewritten version.
But the real difference appears after you read and test the output.
Seeing the features of both tools, Super Humanizer remains on the upper hand and seems to offer better results. But what about the quality of the results? How well do they remove AI detection and retain context? And whether they improve or maintain the readability, or destroy it. To find this, we are going to test both of these AI humanizers with a small article written using Claude that has 100% AI detection on ZeroGPT.
To begin testing, we are pasting the AI-written content into Super Humanizer. We have humanized it using the Super Ultra mode. Here are the results we got after humanizing the text.
Now that we have the humanized version, next we are going to check the AI detection performance. For this, we ran this humanized text by Super Humanizer through ZeroGPT and got the following results.
ZeroGPT found 0% AI detection in the content humanized using Super Humanizer. It says that the provided text is fully human-written. So, after the features, Super Humanizer performed well on the AI detection side too.
But what about the content readability?
To assess the content readability and quality, we read the humanized version multiple times. And, based on the experience of our content editing and writing team, this content reads better.
The tool retained headings like the title & topic and most of the remaining headings. It only removed technical jargon, brought variations in sentence structure, and introduced some simple vocabulary into the content.
If we talk about the SEO side, Super Humanizer kept most of the keywords. Those that were replaced seem to have a good synonym choice that didn’t disturb the context.
To test Clever Humanizer to its full potential, we are humanizing the same AI-written article that we used to test Super Humanizer. Here’s the humanized text we got from Clever AI Humanizer.
Proceeding with our testing process, we are going to run an AI detection for this text using ZeroGPT. The screenshot below shows the results we got this time for the text humanized using Clever AI Humanizer.
As per the AI detection results, Clever AI Humanizer failed to remove AI detection from the content. However, it reduced the score from 100% AI to 23% AI. Still, if compared with Super Humanizer, the difference is huge. Because Super Humanizer clearly delivered 100% human content.
Assessing the content further humanized by Clever AI Humanizer, we found the readability somewhat satisfactory. However, the vocabulary choice is at an advanced level, making the text difficult to read for an ordinary reader.
After testing both tools with the same AI-written content, Super Humanizer is the clear winner. It delivered better readability, kept the context and keywords, and reduced AI detection to 0% in our test.
Clever Humanizer also improved the content, but its 23% AI score and advanced word choices made it less effective.
So, if you want better human-like content that stays simple and SEO-friendly, Super Humanizer is a good choice.
