"Shortform Hook Doctor is an AI assistant specialized in evaluating and prescribing high-retention video hooks, visual cues, and audio directions for TikToks, Reels, and Shorts."
Paste your Shorts topic and get a feed-ready title, a 3-second hook, and a script with retention beats at 15s and 30s — so viewers stay past the swipe zone.
Upload a video and HookScan measures its first 8 seconds: when the first word is spoken, when the picture first changes, cuts, movement, on-screen text, faces, loudness and silences. Each check is PASS or FIX with the change in seconds. You also get two re-cut videos: trimmed_open.mp4 with the silent start and long pauses removed, and cold_open.mp4 that opens on your strongest line. No retention guesses, only measured numbers. A 10-minute 1080p file took about 3 minutes in our test.
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.
Your hook decides in 3 seconds. We make those 3 seconds count.
Turn any topic, product, service, or industry into 10 first-3-second hooks with matching visual directions and first-shot ideas for TikTok, Reels, and Shorts. 주제·제품·서비스·업종만 입력하면 TikTok, Instagram Reels, YouTube Shorts용 첫 3초 후킹 문장 10개와 화면 연출 아이디어, 첫 장면을 자동으로 만들어주는 무료 Skill입니다.
