Overview

Custom templates allow you to use your own PowerPoint template designs when generating presentations. Upload your branded template once, then use it across unlimited presentations.

​
How It Works

  1. Upload your PowerPoint template (.pptx)
  2. Get a unique template ID
  3. Generate presentations using your template ID
  4. Your presentations will automatically use your custom design

​
