Grubby AI is a free, no‑login tool that rewrites AI‑generated content to sound natural and undetectable, claiming a 100 % human score against AI-detectors while preserving meaning, context, and SEO value.
Grubby AI lets users paste AI-generated text and hit Humanize—instantly rewriting it to sound more natural and less detectable. With no account or cost, it’s ideal for quick tasks: school emails, drafts, and notes. It supports multiple languages and browser types and aims to keep SEO signals intact. However, real-world tests show it averages only ~60 % human scores—far from foolproof. Users also report odd meaning shifts and inconsistent performance in certain regions.
