Everything you need to know about Grammy, the free AI text humanizer. Try it now →
Grammy is a free, browser-based AI text humanizer. It removes the tell-tale patterns of AI-generated writing (from ChatGPT, Claude, Gemini, and similar tools) and rewrites the text so it sounds genuinely human. You choose the style — grammar flaws, dyslexic flair, or Twitter/X slang — and Grammy applies it instantly.
Paste your text into the editor, pick one or more humanization styles, and click the button. Grammy sends your text to a Google AI backend which rewrites it according to the chosen style while preserving your original meaning. Results appear in seconds.
Yes, Grammy is completely free. There is no paid plan, no subscription, and no account required. Just visit grammy.mrhumble.lol and start humanizing.
Grammy offers three styles: (1) Human Flaws – adds subtle grammar slips and occasional typos to soften unnaturally polished text. (2) Dyslexic Style – uses phonetic spelling and natural-looking letter slips for a deliberately rough voice. (3) Twitter Slang – converts formal wording to casual internet English ("bc", "rn", "tbh", "gonna"). You can combine any of the three.
