AI analyzes YouTube videos before you click. See scores, summaries, comment insights & transcripts on thumbnails. Stop wasting time on low-quality YouTube videos. CleoSum uses AI to analyze any video before you watch it — so you know what's worth your time. Hover over any YouTube thumbnail to instantly access four powerful tools: Analyze, Summarize, Comments, and Transcript. CleoSum works everywhere on YouTube — the home feed, search results, channel pages, and the watch page sidebar. FEATURES -- Analyze -- Get a full video breakdown in seconds. CleoSum's AI evaluates usefulness score (0-100), content density, filler detection, key topics, target audience, and a clear watch/skip/skim recommendation. Color-coded stat bars make it easy to see quality at a glance. -- Summarize -- Read a structured summary instead of watching the whole video. Includes a TL;DR, key points, timestamped sections you can click to jump directly to that moment, and notable quotes. Perfect for research, studying, or catching up fast. -- Comment Analysis -- Understand what the community thinks without scrolling through hundreds of comments. AI extracts the overall sentiment, recurring themes, top insights, and flags any controversy — so you get the pulse of the audience instantly. -- Full Transcript -- Access the complete video transcript with clickable timestamps. Copy the entire text to your clipboard with one click. Great for note-taking, quoting, or reading at your own pace. -- Watch Page Panel -- On the video watch page, CleoSum adds a dedicated panel below the video player with all four tools accessible without hovering. Your analysis stays visible while you watch. -- Deep Analysis (Pro+) -- Upgrade to Pro+ and unlock Deep Analysis mode — powered by a more capable long-context AI model for sharper, more thorough summaries on long-form content. 10 Deep Analyses per day on top of your 100 standard analyses. -- Share and Copy -- Copy any analysis or summary to your clipboard with one click. Share insights with your team, paste into notes, or save for later. -- Customization -- Adjust font size and analysis language. Supports 40+ languages, including English, Spanish, French, German, Chinese, Japanese, Korean, Arabic, Hindi, and many more. HOW IT WORKS 1. Install CleoSum from the Chrome Web Store. 2.
