Textumi: AI Detector & Humanizer

Check text on any page for signs of AI writing and rewrite it in a natural, human style that keeps your facts.

Textumi brings the AI Detector and the Humanizer of textumi.com to every web page, in a side panel that stays open while you browse. AI DETECTOR • Check selected text, the main text of the current page, text you paste — or a whole site. • See the result on the same five-band scale as on textumi.com: Human-written, Mostly human, Mixed: human and AI, Mostly AI, AI-generated. • Find the passages marked for review right on the page. Highlights never change the page itself. • The result is an estimate from the style of the text, not proof of authorship. Short, formulaic or heavily edited text can be misclassified. Use it as a starting point for review, never as the sole basis for a consequential decision. HUMANIZER • Rewrite selected or pasted text so it reads more naturally and keeps its meaning and facts. • Keep your formatting, copy the result or put it back into the field you are editing. • Optionally translate before rewriting, or apply your own writing style (My style). • Rewriting does not guarantee a particular result from any detector. Review the facts and tone before you use a draft. WHOLE-SITE SCAN • Find the pages of a site from its sitemap, see how many words the check needs before you start, and get a report of pages per band with a CSV export. YOUR ACCOUNT • The same account, plan and allowance as on textumi.com. Sign in with Google, Apple or e-mail on textumi.com; the extension never sees your password. • Your remaining words are always visible in the panel. • 17 interface languages, light and dark themes, keyboard shortcuts and screen-reader support. PRIVACY • Textumi reads a page only when you ask it to. Nothing is sent until you press a button. • No browsing history is collected and no analytics run in the extension. • Detection runs on Textumi's own servers. Rewriting sends your text to an external AI model provider, as described in the privacy policy.
