User-generated-style ads outperform polished brand spots because they feel like a person, not a billboard. You don't need a creator, a camera, or a studio to make one.
The 3-minute version
- Open Product Ad and drop your product — a URL to scrape, or images from your brand catalog.
- Pick an avatar — choose from the library, generate one, or bring your own clone.
- Write the script — or let the Copilot write it from your product. Three short lines is enough: hook, value, CTA.
- Render. Krex AI lip-syncs the avatar, cuts in your product as B-roll, burns in karaoke captions, and outputs a vertical 9:16 video.
What makes it land
- Hook in the first line. The avatar's opening sentence decides whether anyone watches the rest.
- Show the product. B-roll cut-ins beat a static talking head — Krex AI does this automatically.
- Captions on. Most feeds play muted; burned-in captions are non-negotiable.
Make ten, not one
The real unlock is volume. Once you have a winner, vary the hook and re-render — or hand it to Automation and let it produce and schedule a week of variations while you do something else.
