What each tool does
Synthesia lets companies produce videos without cameras or actors. You write a script and a lifelike AI avatar presents it, which makes it practical for training material, internal updates and learning content. It supports more than 160 languages, includes an AI assistant for creation, and exports to an LMS or other video platforms. It is a paid business tool with enterprise options.
HeyGen turns ideas into videos starring a lifelike AI avatar, which can even look like you. You supply text, an image or audio, and it builds a complete video with narration, captions, visuals and animations. It is used for social content, online courses and business videos in fields like real estate, legal and finance.
Key differences
- Focus: Synthesia is built around corporate training and communications; HeyGen covers social, course and business content.
- Input: Synthesia starts from a script; HeyGen accepts text, images or audio.
- Personal avatar: HeyGen highlights avatars that look like you.
- Learning systems: Synthesia offers easy export to LMS platforms and 160+ languages.
- Pricing: Both are listed as paid; HeyGen mentions a free way to get started. Check each pricing page for current plans.
Which should you choose?
Choose Synthesia if you work in HR, L&D or internal communications and need consistent training videos, often in several languages, that plug into your learning system.
Choose HeyGen if you are a creator, teacher or small business owner who wants presenter videos for social media or online courses, possibly with an avatar of yourself. Both usually require card payment in USD.
Can you use both?
They overlap heavily, so most people should pick one. A company might use Synthesia for internal training and HeyGen for public marketing videos, but that is only worth it at larger scale.
