How is HeyGen different from Synthesia?

Both generate avatar-presented videos from a script, but HeyGen leans more toward marketing use cases and is particularly known for lip-sync dubbing — relocalizing existing video into other languages with the speaker's mouth movements matched to the new audio.

Does HeyGen have a free plan?

Yes — a free tier with a limited number of monthly video credits, enough to test output quality before committing to a paid plan for higher volume.

Can HeyGen create a custom avatar of a real person?

Yes, custom avatar creation is available on higher tiers, on top of the stock avatar library included by default.
