Comets AI is a free Chrome extension that helps users search, filter, and analyze YouTube comments using artificial intelligence.

It works on any public YouTube video and allows users to instantly find specific comments, understand overall sentiment, and detect emotions such as joy, frustration, excitement, and sarcasm—without scrolling through thousands of replies.

Key capabilities include keyword and topic-based comment search, sentiment and emotion filtering, AI-generated summaries of large comment sections, and visual insights into trending discussion topics. The extension is lightweight, runs only when activated by the user, and processes comments on demand.

Comets AI is designed for YouTubers, marketers, researchers, and everyday viewers who want to quickly understand audience reactions, brand perception, or community feedback directly from YouTube comments.

The product requires no account or login, is privacy-first, and does not track browsing behavior or store watch history. Core functionality is completely free.

Comets AI positions itself as an AI-powered alternative to traditional YouTube analytics and comment tools by focusing on real-time sentiment, emotion analysis, and fast comment discovery.
