On this page

You can have solid research, relevant sources and a well structured argument; your writing can still feel stiff. This happens because every paragraph follows the same pattern. Sentences sound more complex than they have to be or they just don’t have a natural flow.

That’s the reason why AI humanizers have become popular among students and academic writers. These tools explain themselves as the best and they humanize robotic or overly polished writing. It makes the writing more readable and natural.

So use these tools just for humanization and after that, edit the writing and analyze it to make sure it contains all the necessary details.
