Comment Vibe

Comment Vibe uses Chrome's built-in AI (Gemini Nano) to analyse the tone of your comments in real time — before you hit Post.

HOW IT WORKS
Type a comment on LinkedIn, Twitter/X, YouTube, or any other site. A small badge appears near your text box showing the detected tone. Click it to see why — and if your comment sounds harsh or toxic, get an instant, kinder rewrite suggestion you can copy in one click.

SENTIMENT 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 something other than English? Comment Vibe automatically detects your comment's language and shows the tone label, the explanation, and the rewrite suggestion in that same language — so the kinder version is ready to paste, no translating needed. (Powered by Chrome's on-device Language Detector and Translator APIs.)

WHY COMMENT VIBE?
• Catch negativity before you regret posting it
• Improve your online communication habits
• Get AI-powered rewrite suggestions instantly
• Works in your own language, not just English
• Works on LinkedIn, Twitter/X, YouTube, Reddit, and more

100% PRIVATE — NO DATA LEAVES YOUR DEVICE
All analysis is done locally using Chrome's on-device Gemini Nano model. Your comments are never sent to any server. No account required.

REQUIREMENTS
• Chrome 138 or later, on desktop (Windows, macOS, or Linux)

• No flags needed on Chrome 138+. On older builds (127–137) only: open chrome://flags, set "Prompt API for Gemini Nano" to Enabled, then update "Optimization Guide On Device Model" at chrome://components
