Both platforms turn a script into a presenter-led video with a talking avatar. The split is simple: HeyGen moves fast for creators and marketing, Synthesia is built for enterprise training at scale.
HeyGen – creator speed
Avatar cloning from a short selfie video, instant translation with lip-sync across 175+ locales, and an API that marketing teams actually use for personalised video. The free plan gives three videos a month; paid tiers start around $29 for creators and scale to enterprise seats.
Synthesia – enterprise depth
230+ verified avatars, 140+ languages, one-click PPT-to-video, SCORM export for LMS platforms, brand kits and SOC 2-grade controls. Collaboration is first-class, which is why most Fortune 100 L&D teams run on it. Entry pricing starts at $29 per month with custom plans above.
How to choose
- Social ads and personalised outreach: HeyGen.
- Training, onboarding, compliance: Synthesia.
- Both: start free on each, check your language against their locale lists.
Switching is cheap early – test your real script on both free plans before committing.
