Undelve: AI Writing Checker

Catches the words and habits that make writing sound like AI, while you type. Runs entirely in your browser and collects nothing.

Everyone knows the tells now. "Delve." "It's not just X — it's Y." The em-dash pileup. The paragraph that ends by "underscoring the importance of our shared vision." Whether AI wrote your draft or you just write like that naturally, readers are judging, and you only find out after you hit send. Undelve underlines the tells while you're still typing. WHO IT'S FOR - You use AI for drafts and don't want your emails, posts, and docs to read like everyone else's AI drafts - You write everything yourself and you're tired of being side-eyed for loving em dashes. See exactly what's triggering people, and decide what stays. HOW IT WORKS 1. Type anywhere: Gmail, LinkedIn, forums, comment boxes, most editors 2. Undelve underlines AI-associated words, stock phrases, hollow constructions, and statistical patterns (clause-glue density, uniform sentence rhythm, transition stacking) 3. Hover any underline for the why and the source. Every rule is cited, from a published Science Advances word study to Wikipedia's editor-maintained field guide. 4. You decide: rewrite it, keep it, allow the word, or turn off the rule WHAT YOU GET (FREE, NO ACCOUNT) - 177 cited rules across vocabulary, phrases, constructions, and statistics - A slop score with a full breakdown in the popup - Per-site on/off, sensitivity levels, per-rule controls, personal allow-list - Calibrated to respect human style: em-dash lovers don't get shouted at. Defaults only speak up when density gets truly unusual. PRIVATE BY ARCHITECTURE Undelve makes zero network requests. It runs without a server, without accounts, and it keeps no analytics; the extension's only permission is local storage for your settings. Your writing never leaves the page you're typing on. Read the privacy policy (it's one short page). WHAT IT ISN'T Undelve doesn't rewrite your text (yet), and it doesn't pretend to compute an "AI probability." It's a mirror. It shows you what makes text read as AI and teaches you why, so the words that go out under your name sound like you. Fooling people is someone else's business. English only for now. Google Docs is out of reach (it draws its editor in a way extensions can't read), and a few heavily custom editors may be too. Everything else, Undelve just works on. Stop sounding like everyone's chatbot. Sound like yourself. (Yes, we ran this listing through Undelve before shipping it. The quoted examples flag. The rest is clean.)
