AI Detectors

Humanize.io is an AI text humanizer that rewrites AI-generated content to bypass detectors such as GPTZero, Originality.ai, and Turnitin. It offers Light, Medium, and Heavy rewriting modes, a built-in AI checker, and multilingual output.

ABOUT HUMANIZE.IO

Humanize.io leans on a three-mode rewriter with Heavy mode positioned for the strictest detector environments. Free users get two runs a day with no login, and the paid tier removes word caps entirely on both monthly quota and per-request length.

OVERVIEW

Who is it for?
Writers, students, marketers, and SEO teams who need to rewrite AI-generated drafts so they pass detectors while keeping keywords intact.
Problem
AI drafts frequently get flagged by GPTZero, Originality.ai, Copyleaks, ZeroGPT, and Turnitin, and manual rewriting is slow and can strip out SEO keywords.
Solution
Humanize.io offers Light, Medium, and Heavy rewriting modes, a built-in AI checker that aggregates scores from multiple detectors, SEO-aware keyword preservation, and multilingual output across 30+ languages. The free tier gives 200 words per month with two runs a day without signup.
What makes it unique
Three rewriting intensities with Heavy positioned for the strictest detector environments, an aggregated multi-detector AI checker in one interface, and an unlimited words plan at 9.99 USD per month annually.
