We ran the same AI paragraphs through a popular AI humanizer and through neepora, then checked both with an AI detector and read them line by line.
Rome, a city of over a million inhabitants by the first century BCE, was utterly dependent on imported grain to feed its populace, particularly the vast numbers of urban poor.
Rome, the city of over a million people at the time, relied totally on imported grain for its sustenance, especially that of millions of poor citizens.
Date deleted. A city of one million now has millions of poor citizens.
Indeed, in the first century BC, Rome had over one million inhabitants, and it was almost entirely dependent on the import of grain to feed its urban poor.
Date, population and urban poor all kept.
Thank you again for your time and consideration. I look forward to hearing from you regarding the next steps in the hiring process.

Both closing sentences deleted. The email just stops.
Thanks again! Hope to hear from you soon!
The thanks and the hope to hear back are both kept.
Other humanizers usually get past AI detectors too. The difference is whether the text still says what you wrote.
Mostly yes, if the only question is the score. Most AI humanizers can move a detector result. The harder question is what happened to the text on the way.
In the examples above, both versions read as human to the detector. Only one of them still has the date, the right population and the closing line of the email.
The same check each time, and you can repeat it with any tool.
"Over a million inhabitants" becomes "millions of poor citizens". The sentence still sounds fine. It is just no longer true.
Whole sentences are cut to make the text less regular. In the email above, the closing was deleted.
Deliberate typos and odd word choices can lower a score. They also make you look careless.
Invisible characters and look-alike letters fool some detectors until the next update, and break when the text is copied.
It cannot guarantee a result on every detector. Detectors are built differently, change often and disagree with each other, so a promise of 100% is a red flag.
It cannot check your facts for you or decide what you are allowed to submit. Read the result before you use it, and see our responsible use page for where a humanizer fits and where it does not.
They can change how a text scores on an AI detector. Whether they work for you depends on whether the rewrite still says what your draft said, which is why we compare the text and not only the score.
We make one, so do not take our word for it. Run the same paragraph through each tool you are considering, then compare the facts line by line using the steps above.
