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.
Other hook tools give you a score. This one refuses to. It measures which axis your own numbers support, and throws out the ones they do not. Paste your hooks with their real numbers. It builds candidate axes from your own copy, tests within-group homogeneity first, and only then compares groups. An axis whose groups are not internally consistent is rejected, not crowned. Ships with one measured prior: name the specific thing, not the category. On 14 ad creatives that ran 2.44x on CTR.
Generate 5 scroll-stopping TikTok hook variations optimized for the For You Page algorithm — each built on a different psychological pattern (shock, question, list, story, visual demo), with shot direction and a why-it-works rationale. Use when you want TikTok opening hooks, need to grab attention in the first 3 seconds, or mention FYP. Output is a creative starting point for you to adapt.
Describe your product and get 3-5 scroll-stopping TikTok Shop hook scripts in 5 minutes — each a different proven pattern, scripted second-by-second from opening line to CTA, with on-screen text and the reason it holds attention. Built for sellers and creators who film their own videos but keep losing viewers in the first second. Test multiple openings, let the algorithm pick the winner. No account access — you describe, you film.
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 your weak hook or video topic — get 5 rebuilt hook variations with diagnosis, director notes, text overlay suggestions, and retention predictions. Stop losing viewers in the first 3 seconds.
Turn a weak Shorts, TikTok, or Reels opening into a stronger before/after hook pack with scripts, captions, titles, and Seedance 2.0 / KingAI-ready video prompts.
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.
