AI UGC
How do I create UGC-style ads with AI avatars?
Write a 15 to 30 second script with one hook, one problem, the product and one call to action. Generate the avatar delivering it, add real product shots, burn in captions, and export 9:16. Then make two or three alternative opening hooks on the same body, check every frame, and launch them together.

Step by step
- Pick one claim the product page supports and one customer problem it solves.
- Write the script in the customer's words: hook, problem, product, proof, call to action. Spell the brand name phonetically if needed.
- Choose the avatar and setting to match who buys the product and where they'd use it.
- Render the presenter delivering the script.
- Insert real product footage for close-ups instead of asking the AI to fake packaging.
- Add captions and an end card, keeping text inside the safe zone. Export 9:16, which TikTok recommends, plus 4:5 for Meta feeds.
- Make 2 to 3 alternative hooks on the same body.
- Launch them together with equal budgets.
Quality checklist before launch
- Lip sync matches on every line, including the brand name.
- Hands and fingers look natural in every frame.
- No garbled text on packaging or backgrounds.
- The presenter doesn't claim to be a customer, doctor or expert.
- Every claim matches the label or product page.
- The AI label is on where the platform requires it (TikTok's rules).
Common mistakes
Starting from the tool instead of an angle, using the same avatar for every ad, and launching one version instead of a set of hooks.
