Pricing Compared
Pricing checked July 2026; both vendors run frequent promotions and meter differently, so confirm current numbers before subscribing.
| HeyGen | Synthesia | |
|---|---|---|
| Free plan | Yes (1 credit, test only) | No free plan |
| Entry paid | Creator $29/mo ($24 annual) | From ~$18–$29/mo (annual) |
| Higher tiers | Pro ~$49–$99, Business $149 | Creator ~$67–$89, Enterprise custom |
| Metering | Unlimited standard video; premium features use credits | Minute-based (1 credit = 1 min) |
| Languages | 175+ | 140+ |
The key difference: HeyGen’s headline “unlimited” applies to standard avatars, but its best features — Avatar IV, video translation, AI video agents — draw from a monthly premium-credit pool that can drain faster than expected. Synthesia meters everything the same way, which makes budgeting simpler even if the entry allowance is small.
Avatar Quality
HeyGen’s Avatar IV is the most realistic AI avatar technology available in 2026 — in independent testing, reviewers struggled to tell its output from real footage. Synthesia’s Express-2 avatars prioritize stability and polish over raw lifelikeness, which actually suits long-form training where consistency matters more than looking indistinguishable from a filmed presenter. If a viewer-facing marketing video needs to wow, HeyGen leads; if an internal course needs to stay clean across dozens of modules, Synthesia’s steadiness is an advantage.
Who Should Choose Each
Choose HeyGen if you’re a creator, marketer, or small business making avatar videos for social media, product demos, or multilingual campaigns, and you want the most convincing avatars at a reasonable per-video cost. Choose Synthesia if you’re an enterprise or L&D team that values compliance, collaboration, and structured production with costs you can forecast to the minute.
Frequently Asked Questions

Yes — a genuine free tier with a single credit (about one minute), meant for testing. Synthesia does not offer a free plan as of 2026; you start on a paid tier.
Which supports more languages?
HeyGen, with 175+ languages and real-time translation with lip-sync, versus Synthesia’s 140+. For multilingual-first strategies, HeyGen has the edge.
Final Verdict
