Avatar Studio

Browse preset talking-head avatars, generate a custom one from a description, or upload your own portrait to reuse across the ad tools.

Avatar Studio is where you choose the face that fronts your ads. Set it once and that avatar carries into every tool that uses a talking head.

What it does

You can browse a catalog of preset talking-head avatars, generate a custom avatar from a written description, or upload your own portrait. For a custom avatar, you describe traits like ethnicity, age, and vibe, and Krex AI generates a matching face. Whichever avatar you choose is saved and reused across the ad tools so you don't reselect it each time.

How to use it

  1. Open Avatar Studio from My Brand.
  2. Browse the preset avatars, or start a custom one.
  3. For a custom avatar, describe the traits you want — ethnicity, age, style, and overall vibe.
  4. Or upload a clear, front-facing portrait to use your own image.
  5. Save the avatar so it's available across the ad tools.
  6. Select it when building a Product Ad, talking-head video, or Copilot ad.

Tips

  • Be specific with custom-avatar descriptions — name the traits you want rather than leaving them open.
  • Uploaded portraits work best when the face is well-lit and looking at the camera.
  • Save more than one avatar if you run different audiences or brands.
  • Pair your avatar with a chosen voice for consistent talking-head renders.
