The bottom line
Both HeyGen and Synthesia are solid choices for ai video. HeyGen takes our recommendation with an overall score of 7.4/10. HeyGen is Synthesia's strongest competitor and wins on personalization features. The ability to create hundreds of personalized sales videos from a template, or dub existing content into new languages with lip-sync, makes it particularly valuable for marketing and sales teams. The credit system requires planning, but the output quality justifies the investment for teams producing video at volume.
That said, Synthesia (7.4/10) has its own strengths. Synthesia is the best option for creating professional training and onboarding videos without a camera crew. The AI avatars are impressively realistic, and the multilingual support is genuinely useful. Expensive, but it replaces a much more expensive production process.
