A free AI tool that scores the first three seconds of a short-form video — the opening hook — so you can test whether it will stop the scroll before you post.

HowHooking is a free AI tool with one job: it scores the opening of a short-form video. You upload a clip and it rates the first three seconds — the hook — so you get a quick, objective read on whether the start will stop the scroll or get swiped past. It is aimed at the formats where the first moment decides everything: TikTok, Instagram Reels, and YouTube Shorts.
The premise is that the hook is the highest-leverage part of a short video and the hardest thing to judge on your own. Creators usually decide whether an opening "works" by watching it back a few times or asking a friend — both unreliable. HowHooking replaces that guesswork with an AI assessment you can run before you publish, turning "I think this opening is fine" into a score you can act on. Run across a batch of cuts, it becomes fast triage: which videos are ready to post and which need a stronger first three seconds.
Keep its scope in mind. HowHooking is a diagnostic, not a studio. It tells you the hook is weak; it does not write a better opening line, generate a new hook, re-edit the clip, add caption or hook-text overlays, or publish anything. It reads the first three seconds and hands back a verdict — everything you do with that verdict happens in other tools. The exact score scale, the model behind it, and any paid features were not publicly detailed at the time of writing, so treat the score as one signal, not a guarantee, and confirm current terms on the tool directly.
HowHooking is the smoke alarm; [Kompozy](/) is the crew that puts the fire out. A low HowHooking score tells you the first three seconds are weak — but a scorer can't fix them. Kompozy can, in ways a checker never could. When the hook fails, you rebuild it inside Kompozy: Persona VFX HeyGen prepends a five-second generative VFX opener that Kompozy AI-ranks against your script before it commits, so the strongest hook wins; [HyperFrames](/glossary/hyperframes) layers hook text that reads on mute in that critical first second; a Listicle or Naturalistic Video leads with a title card built to stop the scroll; and governed copy on managed Claude and OpenAI models rewrites the spoken opening line in your [Persona Brief](/glossary/persona-brief) voice. Re-score in HowHooking and you have a closed loop: diagnose, regenerate, confirm.
Then Kompozy does the half HowHooking never touches — shipping. Once the hook lands, the same engine burns in branded captions, reframes the clip to 9:16, 1:1, and 16:9, and fans it across the eight social platforms plus blog and email from one queue on [Autopilot](/glossary/autopilot) behind a per-post review gate. And because Kompozy generates net-new formats — [Persona Shorts](/glossary/persona-shorts), [Persona Frames](/glossary/persona-frames), carousels, quote cards, blogs — you can spin the winning idea into a week of posts, each with its own strong opening. HowHooking grades one hook; Kompozy builds the hook, then builds everything around it and publishes it.
HowHooking is a free AI tool that scores the first three seconds — the hook — of a short-form video you upload, so you can test your opening before posting. It is built for Reels, Shorts, and TikTok, where the first moment decides whether someone keeps watching.
Yes — at the time of writing it is positioned as a free tool for scoring a video hook. Specific usage limits or any paid features were not publicly detailed, so check the tool directly for current terms before you rely on it.
No. It only scores the opening; it does not rewrite the hook, re-edit the clip, add captions, or publish. Acting on the score happens elsewhere — for generating a stronger hook and then publishing, that is what an engine like Kompozy is for.
A clipper cuts long video into shorts and may predict how a whole clip will perform; HowHooking judges only the first three seconds of a finished short. They answer different questions and can be used together — clip in one, gut-check the hook in the other.
Regenerate the opening in Kompozy: prepend an AI-ranked VFX hook, add HyperFrames hook text that reads on mute, or rewrite the spoken opening line in your brand voice, then re-score. Kompozy also captions, reframes, and publishes the result across nine destinations.
