Which Should You Choose?
FAQs
Is HeyGen or Synthesia better for marketing videos?
HeyGen wins for marketing. It has more realistic avatars, 300+ marketing-specific templates, better pricing for small teams, and the best video translation feature — perfect for multilingual campaigns. Synthesia's strengths (LMS integrations, compliance certifications, large avatar library) are more relevant to enterprise training than marketing content.
Which AI video tool is better for corporate training?
Synthesia is better for corporate training, specifically L&D teams in regulated industries. It offers SCORM export for LMS platforms (Workday, SAP SuccessFactors), ISO 27001 certification, advanced RBAC for team management, and has been the category leader for training video creation since 2017. HeyGen can produce training videos but lacks the deep LMS infrastructure.
How does HeyGen's video translation compare to Synthesia?
HeyGen's video translation (dubbed 'Video Translation') is one of its standout features — it can translate any existing video into 40+ languages with synchronized lip movements, matching the original speaker's face. Synthesia can create videos in 130+ languages but doesn't translate existing footage as seamlessly. For localizing existing video content, HeyGen is the better choice.
Can I create a custom AI avatar of myself?
Yes, both platforms support custom avatars. HeyGen creates a custom avatar from a 2-minute video recording and it's available on most paid plans. Synthesia creates custom avatars from a 1-minute clip but requires the Creator plan ($59/mo) or higher. Both produce high-quality results. HeyGen's avatar creation is slightly easier and available at lower price points.
What's cheaper — HeyGen or Synthesia?
HeyGen is significantly more affordable at the entry level. HeyGen has a free tier (3 videos/month) and Creator plan at $29/mo. Synthesia starts at $18/mo (Starter) but with only 10 video exports, and its Creator plan is $59/mo. For equivalent functionality, HeyGen delivers more value per dollar for individual creators and small teams. Synthesia's enterprise pricing is competitive for large deployments.
Are there good free alternatives to HeyGen and Synthesia?
HeyGen offers the best free tier with 3 full video exports per month — enough to test the platform seriously. Other alternatives include: D-ID (free tier available, less polished avatars), Runway (not avatar-focused but powerful AI video), Fliki (text-to-video with avatar option, affordable). For fully free use at scale, open-source alternatives like SadTalker exist but require technical setup.
