Both platforms are strong for corporate training, but Synthesia has built its reputation specifically around enterprise use cases with dedicated training video templates and SCORM export capabilities. At $19/month for the Starter plan, Synthesia offers an affordable entry point for creating professional training content. HeyGen at $29/month also supports training videos but is particularly strong in multilingual video translation.

HeyGen can serve as a viable alternative to Synthesia for most AI avatar video needs, especially given its free tier and competitive pricing at $29/month.
