What is Comment Scope
Analyze YouTube comments and transcripts with AI. Get deep insights, sentiment, and personas plus a powerful scraper & CSV exporter. Unlock deep audience intelligence with AI. Stop guessing and start growing with CommentScope, the ultimate YouTube Comment Analyzer and Audience Research Tool.
Comment Scope is a professional-grade toolkit that uses advanced AI (Gemini 2.5 / 3.x Flash & LLaMA 3.1) to transform thousands of chaotic comments and hours of transcripts into clear, actionable growth strategies in seconds. Whether you are a Creator, Researcher, or Brand, Comment Scope provides an AI Video Summary and a 360-degree view of audience sentiment that other tools miss.
WHY COMMENT SCOPE IS DIFFERENT Most analyzers only look at comment text. CommentScope uses Dual-Intelligence Technology: it reads the video's Transcript and Description alongside the Comment Section. This ensures every summary is 100% factual and every insight is rooted in what was actually said in the video.
KEY FEATURES:
1. AI-Powered Audience Summary & Insights Get a deep breakdown of the video's core message and how the audience is reacting. No more reading through thousands of comments to get the "vibe."
2. Deep YouTube Sentiment Analysis View the emotional pulse of your community with precise percentage breakdowns (Positive, Neutral, Negative). Perfect for tracking brand health and audience satisfaction.
