The Hook Lab takes your best-performing concepts and turns each into a set of hooks and captions you can use immediately — grounded in what already works for your audience, not generic templates.
- 1Open the Hook Lab tab. Each block is a proven concept from your data, with several hooks and captions.
- 2Tap Copy on any hook or caption to grab it.
- 3After you post one, tap 'mark used' — that tells Merge what you shipped so future ideas keep improving.
The rules baked in
- Payoff-first: lead with the result, not a setup.
- No question openers — they quietly cut your reach.
- Show the payoff inside the first 5 seconds.
