You already wrote a hook — spoken line and/or on-screen text. Paste it with your platform (TikTok / Reels / Shorts) and get a 0-10 score on 4 things that decide the first 3 seconds: clarity, curiosity gap, specificity, and pace. Each score gets a one-line reason, plus the single biggest fix and one rewritten version. This only grades a hook you already have — it doesn't generate new hook ideas or a script. For 5+ hooks and a full script from a topic, that's a different agent (Hook Lab).
Turn your product facts into nine hooks, three shootable short-video scripts, captions, and a focused testing plan.
HookCraft Studio turns a topic and source material into a complete, fact-checked faceless-YouTube package — not just a hook. You get: 10 scored titles (top 3 shown), a full script (900-1300 words) with a scroll-stopping hook grounded strictly in your source (no invented facts), a mandatory fact-check pass with a reproducible score, and 5 scored thumbnail-text concepts that don't just repeat the title. Built from a method proven on a live YouTube channel.
Predict second-by-second viewer retention for the first six seconds of a short-form video hook, then provide concrete opening fixes.
"An advanced script and content strategy assistant that engineers high-retention 5-second hooks, viral outlines, and engaging video scripts for YouTube, TikTok, and podcasts."
Your hook decides in 3 seconds. We make those 3 seconds count.
Generate 30–100 high-variety hooks for TikTok, Reels, Shorts, ads, products, creators, and social content — with optional visual hooks and A/B variations. Turn one idea into dozens of scroll-stopping hooks.
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.
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.
