Winning Ads

A swipe library of proven video and static ads — browse by niche, then one-click rebuild any ad as your own with your product and avatar.

Why start from a blank page when you can start from an ad that already works? Winning Ads is a swipe library of proven, high-performing video and static ads.

What it does

Winning Ads collects ads that have performed well, in both video and static formats, so you can browse them by niche for inspiration. When one fits, you can rebuild it as your own in one click, swapping in your product and avatar while keeping the structure that made it work. It turns a proven ad into a starting template instead of something you study and try to recreate by hand.

How to use it

  1. Open Winning Ads and browse the swipe library.
  2. Filter by niche to find ads close to your product or audience.
  3. Open an ad to see how it's built.
  4. Click rebuild to make it your own.
  5. Swap in your product and avatar.
  6. Render the result and refine as needed.

Tips

  • Start with ads from your own niche, then borrow ideas from adjacent ones once you've found what works.
  • Keep the structure of a winning ad and change only the product and message at first.
  • Rebuild more than one ad and test them against each other.
  • Pair the format you pick with a strong opener from Hooks.
