Home / Guides / HeyGen vs Synthesia
HeyGen and Synthesia are the two dominant AI avatar video platforms in 2026. Both turn a script into a presenter-led video in minutes — but they are built for different buyers. This comparison is based on current public pricing and hands-on testing notes, last verified July 2026.
Pick HeyGen if you're a creator, marketer or small team: cheaper Pro tier ($49/mo with 4K export), a real free plan (3 videos/month), the more expressive Avatar IV model, and video translation across 175+ languages.
Pick Synthesia if you're buying for a company: 240+ stock avatars, 160+ languages, SCORM export for LMS training, minute-based plans that are easy to budget, and the strongest enterprise governance (SOC 2, content moderation, brand controls).
| HeyGen | Synthesia | |
|---|---|---|
| Starting price | $29/mo (Creator, 600 credits) | $29/mo (Starter, minute-based) |
| Mid tier | $49/mo Pro — 1,000 credits, 4K export | $89/mo Creator |
| Free plan | 3 full videos/month, no card required | ~3 minutes/month |
| Stock avatars | 500+ (incl. Avatar IV, gesture-synced) | 240+ |
| Languages | 175+ (incl. video translation/dubbing) | 160+ |
| Billing model | Credits shared across features | Minutes per month, rollover available |
| Custom avatar cloning | Yes, from short webcam footage | Yes (higher tiers) |
| Training/LMS (SCORM) | — | Yes — core strength |
| Best for | Creators, marketing, UGC-style ads | Corporate L&D, onboarding, comms |
Realism and price. Avatar IV syncs gestures and facial expression to the meaning of your script, which makes talking-head marketing videos noticeably less robotic. HeyGen Pro at $49/mo now undercuts Synthesia's Creator tier ($89/mo) while adding 4K export, and the video-translate feature — re-lipsyncing an existing video into 175+ languages — has no real equivalent at this price. The free plan gives you three complete videos a month, enough to properly evaluate it.
Predictability and governance. Minute-based plans are easier to budget than credits, and rollover means unused minutes aren't lost. For corporate training, SCORM export drops videos straight into your LMS, versioned templates keep 50 videos consistent, and enterprise controls (SSO, moderation, brand kits) pass procurement reviews that creator tools fail. If the video is going into onboarding or compliance training, Synthesia is the safer default.
There is no single winner — the split is buyer type. Individual or small team making content that sells: HeyGen. Company making content that trains: Synthesia. Both have free ways to test, so the cheapest decision is to run your actual script through both before paying.
