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.
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 script runs long and you are recording today. Open one HTML file in any browser - no install, no signup, no API key, no coding tool of any kind - and every line becomes a row you can keep, tighten or cut while the running total moves. It names the lines that would get you to your target, strips stock filler and reports what it cost, finds the block eating the overrun, checks a hook against the first seconds, and exports the recut script, caption cards and a printable shot list. Offline.
