What is the Elai AI avatar video workflow?

Elai focuses on AI-generated presenter videos that use digital avatars and synthesized speech to deliver scripted content.

Built for presenter-led AI video

Elai belongs to the AI avatar video category, where a digital presenter delivers a script. That is different from a workflow whose main objective is preserving the layout and visual content of an uploaded document page by page.

  • Create presenter-led AI videos
  • Use digital avatars and synthesized speech
