Grubby: AI Humanizer - Humanize AI Text Anywhere

Grubby is an AI humanizer that works everywhere you write. Select your text, pick a mode, and Grubby will humanize AI text in place, on the page you are already on. Most AI humanizer tools make you leave what you are doing. You copy your writing into another tab, humanize AI text there, copy the result, and paste it back. Grubby removes all of that. The humanized text replaces the original where it sits. HOW THE AI HUMANIZER WORKS 1. Select at least 26 words in a post, an email, or a document. 2. Click the "Humanize" pill that appears under your selection. 3. Pick a mode, review the result, and click Replace. The result appears in a small card next to your selection. You can replace the original in place, copy it, see exactly what changed, or humanize AI text again in a different mode. Undo is one click in the card. THREE MODES TO HUMANIZE AI TEXT • Academic - recommended for formal and academic writing. • GPTZero - tuned for text that will be checked with GPTZero. • ZeroGPT - tuned for text that will be checked with ZeroGPT. Each mode shows one line of guidance so you know when to use it. AN AI HUMANIZER WHERE YOU ALREADY WRITE This Chrome extension appears on its own in the places students and professionals write most: Google Docs, Gmail and ChatGPT. On any other site, open the popup and choose "Open Grubby on this page". You can switch Grubby off per site at any time. HUMANIZE AI TEXT IN GOOGLE DOCS Grubby reads only the text you select, and "Replace in document" writes the result over that selection through Docs' own input. If the document is view-only, the result is copied to your clipboard instead. A SIDEBAR THAT STAYS PUT The AI humanizer opens as a sidebar on the right edge. In a document editor it takes the companion-panel slot and the page reflows beside it. WHAT THE AI HUMANIZER WON'T DO • It never reads a page in the background. Text is sent to Grubby only when you click Humanize. • It never appears over password, one-time-code, or payment fields. • It never reads your clipboard. • It runs only on a small set of writing surfaces unless you open it on a page yourself. The full list is in the extension's permissions. FREE TO START You need a Grubby account, and free plans are available at grubby.ai. Connect the extension from your Grubby account page in one click; the extension never sees your password. Humanizing uses word credits from your plan, and every button shows the price in words before you commit. Privacy: the text you submit is sent to Grubby to humanize it and is handled like text submitted on grubby.ai. Nothing else is collected from the page. Full details at https://grubby.ai/privacy
