What they are
HeyGen
HeyGen generates studio-quality videos using AI avatars and text-to-speech voices, so creators and marketers can produce talking-head content without filming themselves. It supports over 175 languages and lets you clone your own voice and likeness. Teams use it for product explainers, onboarding videos, and localized content at scale. The avatar quality is impressive for scripted material, but unscripted or conversational styles still feel noticeably synthetic.
Synthesia
Synthesia generates studio-quality videos using AI avatars that lip-sync to a typed script, with no camera, microphone, or editing software required. It targets corporate trainers, marketers, and course creators who need to produce multilingual video content at scale. The output looks polished but has a recognizable AI avatar aesthetic that some audiences find less engaging than real presenters. Pricing starts at $14 per month on the Starter plan.
