Feature-by-Feature Comparison
Avatar Library — Winner: HeyGen
| Aspect | Synthesia | HeyGen |
|---|---|---|
| Stock Avatars | 230+ | 700+ |
| Avatar Styles | Corporate, professional, educational | Diverse, creator-friendly, expressive |
| Custom Avatar | Yes (Creator+, $1000/year for studio) | Yes (1 included free, more on paid) |
| Voice Cloning | Yes (with personal avatar) | Yes (unlimited on Creator+) |
The breakdown:
Synthesia’s 230+ avatars skew corporate—think professional attire, diverse age ranges, and regional looks suited for training, onboarding, and internal communications. If you’re producing compliance videos or global training content, you’ll find avatars that match your use cases.
HeyGen’s 700+ avatars lean into creator-friendly aesthetics—casual styles, expressive faces, and personalities that work on social feeds and marketing content. The larger library means more variety without repeating faces.
Lip-sync quality: Both have improved dramatically. Synthesia’s lip-sync handles technical jargon slightly better. HeyGen’s avatars are more expressive and warm—better for upbeat, personality-driven content.
Bottom line: HeyGen’s larger, more expressive library wins for most use cases. Synthesia wins specifically for corporate/enterprise scenarios where professional polish matters more than personality.
Video Quality — Winner: HeyGen
| Aspect | Synthesia | HeyGen |
|---|---|---|
| Max Resolution | 1080p (4K on Enterprise) | 4K (on Pro+) |
| Render Speed | ~2 min per 1-min video | ~3 min per 1-min video |
| Processing | Faster | Standard to Fast |
| Output Quality | Clean, professional | Clean, expressive |
Resolution breakdown:
HeyGen offers 4K export on Pro ($99/mo) and above. Synthesia caps at 1080p unless you’re on Enterprise. For YouTube, social media, and LMS content, 1080p is usually sufficient. But if you’re producing content for large displays, trade shows, or cinematic presentations, HeyGen’s 4K gives you more headroom.
Render speed:
In head-to-head testing, Synthesia renders roughly 30-40% faster. A 1-minute video takes about 2 minutes on Synthesia vs 3 minutes on HeyGen. This matters when you’re producing dozens of videos weekly—those extra minutes add up.
Quality verdict: HeyGen wins on resolution ceiling. Synthesia wins on production speed. For most users, the quality difference is negligible at 1080p. Choose based on your workflow needs.
Languages & Localization — Winner: Tie
| Aspect | Synthesia | HeyGen |
|---|---|---|
| Languages | 160+ | 175+ |
| AI Dubbing | Yes (with lip-sync) | Yes (with lip-sync) |
| 1-Click Translation | Yes | Yes |
| Brand Voice/Glossary | Enterprise only | Yes (Creator+) |
Both platforms excel at multilingual content:
- Synthesia supports 160+ languages with AI dubbing that maintains lip-sync. Their 1-click translation feature makes global rollouts efficient.
- HeyGen offers 175+ languages and dialects, with brand glossary features to maintain consistent terminology across translations.
For global enterprises: Both handle localization well. Synthesia’s enterprise features (translation proofreading, centralized controls) give it an edge for large-scale deployments.
Enterprise & Security — Winner: Synthesia
| Feature | Synthesia | HeyGen |
|---|---|---|
| SSO/SAML | Yes (Enterprise) | Yes (Business+) |
| Admin Controls | Comprehensive | Good |
| Content Moderation | Priority on Enterprise | Standard |
| Dedicated CSM | Yes (Enterprise) | Yes (Enterprise) |
| SCORM Export | Yes | Yes (Business+) |
| SOC 2 Compliance | Yes | Yes |
Synthesia’s enterprise advantage:
For organizations with strict governance requirements, Synthesia leads:
- More granular permission controls
- Priority content moderation (faster approval)
- Dedicated customer success managers at lower tiers
- Stronger audit and compliance features
- White-glove custom avatar creation
HeyGen’s enterprise offering:
HeyGen’s Business ($149/mo) and Enterprise tiers include solid team features—SCORM export, LMS integrations, SSO, and workspace collaboration. It’s sufficient for mid-sized teams but less mature than Synthesia’s enterprise stack.
Bottom line: If compliance, governance, and enterprise-grade security are priorities, Synthesia is the safer choice.
Ease of Use — Winner: Tie
Both platforms are beginner-friendly with similar workflows:
Synthesia’s UX: Clean, professional interface. Slightly steeper learning curve for advanced features. Better templates for corporate use cases.
HeyGen’s UX: More intuitive for first-time users. The free tier lets you learn without commitment. Templates lean toward marketing and social content.
Editor features both offer:
- PowerPoint/PDF import
- Screen recording
- Brand kits (colors, fonts, logos)
- Auto-captions
- Media library (stock footage, music)
- Template saving
Neither has a significant UX advantage. Both are far easier than traditional video production.
Integrations & API — Winner: Synthesia
| Integration | Synthesia | HeyGen |
|---|---|---|
| API Access | Yes (Creator+) | Yes (Enterprise) |
| LMS (SCORM) | Yes | Yes (Business+) |
| Zapier/Make | Limited | Yes (Business+) |
| Hubspot | No native | Yes (Business+) |
| n8n | Via API | Yes (Business+) |
Synthesia’s API is available starting at Creator tier (360 min/year) with more volume on Enterprise. It’s well-documented and production-ready for automation workflows.
HeyGen’s integrations with Zapier, Make, n8n, and Hubspot are native on Business tier—easier to set up without custom development. API access requires Enterprise.
For developers: Synthesia’s API is more accessible at lower price points.
For no-code automation: HeyGen’s native integrations win on Business tier.

FAQs
Is Synthesia or HeyGen better for beginners?
HeyGen is better for beginners because of its free tier. You can create 3 full videos (up to 3 minutes each) without a credit card. This lets you learn the platform, test avatar quality, and understand workflows before paying. Synthesia’s limited free tier makes genuine evaluation harder.

Both have excellent avatar quality, but they differ in style. Synthesia avatars are more corporate and professional—ideal for training and enterprise content. HeyGen avatars are more expressive and personality-driven—better for social and marketing content. Lip-sync quality is comparable, with Synthesia slightly better on technical jargon and HeyGen slightly better on emotional delivery.
Can I create my own custom avatar?
Yes, both platforms support custom avatars (digital twins). HeyGen includes 1 custom avatar in the free tier and more on paid plans. Synthesia offers custom avatars on Creator+ plans, with studio-quality avatars as a $1,000/year add-on. Both require you to record a short video for training.

Do Synthesia or HeyGen videos look fake?
Modern AI avatar videos are highly realistic. Both platforms have improved dramatically—lip-sync is natural, movements are fluid, and avatars pass casual inspection. Viewers may notice it’s AI on close scrutiny, but for training, marketing, and social content, quality is professional enough that “fake” isn’t the concern.
