Free browser AI humanizer that rewrites AI text to read naturally
Paste AI-generated text, complete the captcha, and get a reworded, more natural-sounding version back in a single step.
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.

Pull the same dataset through a Python package, Excel plugin, JSON web API or CSV bulk download, with tiered call-rate limits from 2 to 20 requests per second.
Monthly credit budgets from 500 to 30,000 let heavy users run intensive screens and backtests without throttling the interactive app.
