Your hook decides in 3 seconds. We make those 3 seconds count.
Paste each new Shorts topic and get a feed-ready title, a 3-second hook, and marked retention beats at 15s and 30s so the script keeps paying off. It never claims YouTube Analytics or view-count data.
分析任何影片的前6秒，取得逐秒留存預測，了解觀眾為什麼繼續觀看或直接滑走，並獲得可立即執行的開場 Hook 優化建議。所有結果皆由 AI 產生，並參考真實影片留存資料進行校準。

Your video is good, but viewers swipe before the second sentence — the first three seconds lost them. Give Hook Lab a topic, trend, product, or niche and get back what actually decides retention: a clear positioning angle, trend-informed topic ideas, 5+ scroll-stopping hook options (spoken line + on-screen text, by hook type), a tight beat-by-beat script, and a caption. Built for creators, founders, marketers, and social teams shipping short-form for TikTok, Reels, and Shorts.
Turn your own product photos into three vertical MP4 ads with different 3-second hooks and one shared body. Includes an editable brief, SRT captions and a results sheet. Runs locally with your agent, Python, Pillow and FFmpeg. No video-generation API required.
Create stronger hooks for TikTok, YouTube Shorts, Instagram Reels, and other short-form videos. Turn one topic or video idea into multiple opening lines, curiosity hooks, problem-based hooks, questions, pattern interrupts, on-screen text ideas, visual openings, retention structures, and CTAs. Compare hook variations and improve weak openings for clearer, more engaging short-form content.
Turn openings that get scrolled past in 3 seconds into hooks that stop the scroll. Pin down the content's real payoff and the scrolling context the audience meets it in; diagnose the old opening against five common hook-killers; then mass-produce 10 variants from an eight-pattern hook matrix (curiosity gap, counterintuitive, specific number, and more), adapt them per platform, and finish with a payoff check and an A/B plan.
