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.
You open the app to post, stare at a blank caption box, and the idea in your head never becomes a video. This turns a rough topic, trend, or product into a finished short-video script in one go: three scroll-stopping hook options for the first three seconds, a full spoken script timed to length, on-screen text overlays, shot-by-shot visual cues, a caption with hashtags, and a filming tip. Built for creators, founders, marketers, and social teams who need to ship, not brainstorm.
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).
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.
A free single-file tool that tells you whether a short-form script fits your target length before you record it. Open the HTML in any browser - no install, no signup, no API key, no coding tool of any kind. Paste your script and get the estimated spoken length, a per-line breakdown marking your first cuts, a hook-length check, a warning for lines too long to read as captions, and a stopwatch that measures your own pace and recalibrates to it. Runs offline; your script is never uploaded.
Your hook decides in 3 seconds. We make those 3 seconds count.
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.
Not just a script writer — get a fully laid-out storyboard PDF with timing, voiceover, camera direction, and captions, so you don't have to organize the shooting script yourself.
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.
