Ai humanizer for school - what do students actually use

what ai humanizer are students actually using for school assignments?

not looking for a debate about whether this is ethical. just want to know what tools people have found work for the academic context specifically, where the detector is usually turnitin or gptzero.

ngl most people i know just use whatever has a decent free tier. the tool matters less than people think for most assignments where the bar is just clearing the basic threshold.
