How to Implement Real-Time Face Swap Preview on Product Page (Pixar/Disney Style)?

Hi everyone! I’m trying to figure out how a site like Loverse.ai creates stylized models (e.g., Disney princesses or Pixar-like 3D characters) and swaps the face with a customer-uploaded photo, showing a real-time preview on the product page. I’d like to build something similar on Shopify:

  • Customer uploads a photo.

  • The face is applied to a predefined model (e.g., a cartoon character).

  • The preview updates on the product page before adding to cart.

Does anyone know how this might have been implemented? What tools or APIs could they be using? Is this possible natively in Shopify, or would it require an external app/integration? If you’ve built something like this, how would you approach it, and what would you charge for this kind of customization? Any tips, tutorials, or references would be greatly appreciated! Thanks!

This is definitely not a native Shopify feature and it would be reliant on an app which is likely making a call to the API of a GenAI platform. A super oversimplified approach would be:

  • create a form where a customer can upload an image
  • create a middleware app that takes the image and sends to to OpenAI/Midjourney API with specific prompts
  • set up some hosting service that can accept and save the images that the GenAI API will generate
  • send back the image to be previewed on the product page
