Plain-English overview

What Express-3 actually is

Express-3 makes stock and approved custom avatars respond more naturally to a script, using sentiment and phrasing to shape facial expression, gesture, and delivery. It is aimed at training, enablement, internal communication, and other presenter-led videos rather than open-ended cinematic generation.

The model is included inside Synthesia plans instead of exposed as a separately priced checkpoint. Buyers should therefore compare the whole platform: video-minute allowances, avatar choices, localization, collaboration, templates, governance, and whether their plan includes the needed API route.

Good fit for

Multilingual training and internal communication
Consistent business presenters at scale
Teams that value templates, governance, and collaboration
