CommentIQ

🔍 EVERY COMMENT, INSTANTLY SEARCHABLE Open the side panel on any YouTube video and search its comments by keyword, then sort by most liked, most replied, newest, or relevance. No more scrolling endlessly to find that one comment — type and it's there. 📊 UNDERSTAND THE CONVERSATION AT A GLANCE A quick-stats panel breaks down total comments, likes, replies, averages and the most-used words, plus an activity timeline showing when the conversation happened — all from the comments themselves. 🧠 ON-DEVICE AI INSIGHTS (on supported devices) On Chrome desktop with built-in AI, CommentIQ analyses the comments entirely on your own machine and surfaces: • Audience sentiment — Positive / Neutral / Critical, plus a mood timeline showing how the room shifts from the first comment to the most recent • A topic map — what people are actually talking about, sized by how often • The questions your audience keeps asking • Content ideas pulled straight from your viewers • Standout comments worth a reply • An AI reply assistant that drafts responses you can copy Every bit of this runs locally through Chrome's built-in AI (Gemini Nano). Comment text never leaves your browser — there is no server. 📤 EXPORT IN ONE CLICK Send any set of matching comments to CSV or Markdown for your own notes, research or content planning. 🎨 MAKE IT YOURS Four themes — Light, Dark, Cream and Umber — switchable any time from the top of the panel. 🔒 PRIVATE BY DESIGN No account. No tracking. No ads. No analytics. No backend. Comments are fetched directly from YouTube on your device, AI runs on-device, and your preferences are stored locally — nothing about what you read or analyse is ever sent to us, because there's nowhere for it to go. ℹ️ GOOD TO KNOW CommentIQ works on YouTube watch pages and needs an internet connection to load comments. The AI insights require Chrome 138+ on desktop (Windows, macOS or Linux) with built-in AI available; Chrome downloads the on-device model once and caches it. Where the model isn't available, search, stats, timeline and export all still work, and you can join a waitlist to be notified when AI insights light up on your device.
