Questions
What does the AI humanizer do?
It rewrites AI-assisted text so it reads naturally, while keeping your meaning. You choose the model and how strongly it rewrites.
Can an AI detector be wrong?
Yes. Every AI detector makes mistakes, including on text a person wrote. Use a score as a guide to review your writing, not as proof either way.
Is Online Humanizer affiliated with Turnitin?
No. Online Humanizer is an independent service and is not affiliated with Turnitin.
Do you keep my text?
Your runs are saved to your History so you can reopen them. You can delete one item or clear all of it at any time, and deleting your account removes everything.
