Short answer: pick Synthesia for professional training, multilingual marketing and business explainers. Pick HeyGen for casual social videos and viral talking heads. Long answer below.
Avatar Realism
On medium-shot business presenters, Synthesia's Expressive Avatars read as slightly more natural — better posture, more controlled head movement, fewer hand glitches. HeyGen avatars have more energy and pop on close-up, social-style framing.
| Use case | Synthesia | HeyGen |
|---|---|---|
| Corporate explainer | 9.3 / 10 | 8.7 / 10 |
| Social talking head | 8.5 / 10 | 9.1 / 10 |
| Long-form course module | 9.4 / 10 | 8.4 / 10 |
| Lipsync from external audio | 8.8 / 10 | 9.2 / 10 |
Pricing
| Plan | Synthesia | HeyGen |
|---|---|---|
| Free | 36 min/year | 1 min per video, watermarked |
| Entry paid | Starter — $29/mo, 120 min/year | Creator — $24/mo, 15 min/mo |
| Mid | Creator — $89/mo, 360 min/year | Team — $69/mo, 30 min/mo |

Voice Support
Both ship strong native voices. Many serious creators bypass both and feed in audio from ElevenLabs for maximum realism. HeyGen's lipsync-from-audio is a touch tighter; Synthesia's native voices are a touch more consistent across languages.
Multilingual Features
Synthesia leads here: 140+ languages with one-click full re-render of the entire video, avatar lip-sync included. HeyGen supports 40+ languages — plenty for most creators but a step behind for large multilingual rollouts.

Editing Workflow
Synthesia uses a slide-based editor that feels like Google Slides + Loom. Non-video teams ramp up in 20 minutes. HeyGen uses a more traditional timeline-style editor — more flexible for creative work but with a steeper curve for non-editors.
Speed
HeyGen typically renders short clips faster. Synthesia is competitive on longer videos and edges ahead on full multilingual re-renders. Real-world difference: usually minutes, not hours.
Best for Businesses
Synthesia. Brand kits, SOC 2 compliance, SSO, central template libraries and the slide editor make it the obvious enterprise choice. Recommended for training, customer onboarding, product release videos and multilingual marketing.
Best for Creators
HeyGen if you live on TikTok, Reels and Shorts. Synthesia if you publish evergreen YouTube explainers, courses, or any content you'll re-use across markets.
