Overview
See how your comment sounds before you post. On-device AI tone check with kinder rewrites. 100% private — nothing leaves Chrome.
Ever hit Post and instantly regretted the tone? Comment Vibe reads your comment as you type and shows you how it sounds — before the internet does. Powered by Chrome's built-in AI (Gemini Nano), everything runs on your device: no servers, no account, no data collection. HOW IT WORKS 1. Type a comment on LinkedIn, X (Twitter), YouTube, Reddit — any site with a text box. 2. A small badge appears next to the box showing the detected tone. 3. Click the badge to see why — and if your comment sounds harsh or toxic, get an instant kinder rewrite you can copy in one click. FOUR CLEAR TONE LABELS 😊 Positive — constructive and friendly 😐 Neutral — balanced and factual 😕 Negative — may come across as harsh or critical 🚫 Toxic — contains aggressive or harmful language SPEAKS YOUR LANGUAGE Writing in Polish, Spanish, Japanese — anything other than English? Comment Vibe detects your comment's language automatically and shows the tone label, the explanation and the rewrite in that same language, ready to paste. No translating needed. (Powered by Chrome's on-device Language Detector and Translator APIs.) WHY PEOPLE USE IT • Catch negativity before you regret posting it • Turn a heated draft into a point that actually lands • Build better online communication habits over time • Works in your own language, not just English • Zero setup — install and start typing 100% PRIVATE, BY DESIGN All analysis happens locally using Chrome's on-device Gemini Nano model. Your comments are never sent to any server. No account, no tracking, no analytics — and it keeps working offline once the model is downloaded. REQUIREMENTS • Chrome 138 or later, on desktop (Windows, macOS or Linux) • Hardware eligible for Gemini Nano — Chrome downloads the on-device model (~2 GB) automatically the first time it's used • On older builds (Chrome 127–137) only: enable "Prompt API for Gemini Nano" at chrome://flags, then update "Optimization Guide On Device Model" at chrome://components. No flags needed on 138+. TIP: The very first analysis can take a moment while Chrome loads the model — after that it's instant.
