In this video, you'll meet Express-3, the newest and most lifelike step forward in AI avatar technology from Synthesia.
Here's what's new: you can now create a custom AI avatar from a single prompt. Just describe the character you want and Express-3 generates it — from super realistic humans, to a cartoon AI avatar, to full 3D animation. Whatever style you need, you type it and it's generated in minutes.
But that’s not all.
When you combine these new customizable AI avatars with the new AI Assistant in Synthesia, it's never been easier to go from idea to finished video — just describe what you want and build the whole thing by typing.
📋 What you'll learn:
→ How to create custom AI avatars from a single prompt
→ Generating avatars in any style — realistic, cartoon, or 3D animation
→ How to make an AI cartoon avatar just by describing it
→ Combining Express-3 avatars with the AI Assistant for effortless videos
Express-3 is the most advanced Avatar model yet 💥
→ Sentiment-aware performances
→ Better lip sync and more natural body motion
→ 2x faster video generation
Express-3 also powers Style Avatars - stylized characters you can create from a prompt or preset today (reference images coming soon) via Avatar Builder.
If you've been comparing AI avatar generators or weighing up Synthesia vs HeyGen, Express-3 is the reason to take another look — this is the most realistic AI avatar tech available, plus the flexibility to create literally any character.
