Hook Lab
Test four openings side by side before you post
The first two seconds decide whether anyone watches the rest. Hook Lab creates alternative openings for any clip, each saved as its own version you can edit and export, and plays them side by side so you can pick with your eyes, not guesswork.
Cold open
Starts right on the strongest moment, with captions and zooms shifted to match.
Question hook
Opens with a question on screen to pull viewers through.
Bold statement
A short, confident title with big one-word captions.
Tight start
Cuts the slow first sentence so it starts mid-action.
