Free browser AI humanizer that rewrites AI text to read naturally

You can use the humanizer directly in the browser without registering, signing in, or installing anything.
The rewrite is designed to retain the original meaning and SEO terms so you do not lose search relevance.
Alongside the humanizer, the site offers paraphrasing, plagiarism checking, grammar checking, and AI detector tools.
