Hook Lab
AI video hook generator and critique
Paste an opening line and get a score, a critique and alternative hooks for short-form videos before you build the full script.
For creators and social teams refining the first line. Compare a question with a demonstration-led opening and choose the promise your footage can actually deliver.
How it works
- Paste the opening line you plan to say.
- Read the score and critique to see where the promise, audience or payoff could be clearer.
- Compare the alternatives and choose the one the rest of your video can deliver. Take it into Script Builder to develop the full draft.
Illustrative example
- Opening to test
- Here are three things to know about our new rain jacket.
- What to look for in the critique
- The line opens with a product announcement. For a commuter, the useful question is what to check before a wet ride.
- Question-led option
- Buying a rain jacket for your bike commute? Check what the hood lets you see when you look over your shoulder.
- Demo-led option
- Watch what happens when I turn my head with this hood up.
