Hooks

Generate scroll-stopping opening lines for your short videos — describe your product or topic and get a batch of hooks to test.

The first line decides whether anyone watches the rest. Hooks helps you write openers that stop the scroll.

What it does

Hooks generates a batch of opening lines tailored to your product or topic. Instead of guessing at one headline, you get several options at once, each taking a different angle so you can test which one lands. Use it to find the strongest opener before you commit to a full render.

How to use it

  1. Open Hooks and describe your product, service, or topic in a sentence or two.
  2. Add any detail that matters, such as your audience or the angle you want to lead with.
  3. Generate to get a batch of hook options.
  4. Skim the list and shortlist the ones that fit your voice.
  5. Copy a hook into your script or carry it into a render as your opening line.

Tips

  • Write a few seconds of pause into your favorites — read each one out loud to check the rhythm.
  • Test more than one hook on the same video idea; small wording changes can shift performance a lot.
  • Feed in a specific pain point or outcome rather than a generic product name for sharper results.
  • Pair the winning hook with a matching shot in Prompt Studio so the visual backs it up.

Find your opener and keep building — get started or send your hook into a render next.
