HeyGen versus Synthesia comes down to what you are making. The honest verdict is that HeyGen is the better fit for marketers, founders, and small teams who want flexible avatar videos, translation into many languages, and a cheaper way in, while Synthesia is the stronger pick for training, onboarding, and corporate communication where governance, SCORM export, and structured team features matter. Both publish credit-based pricing that is hard to translate into finished minutes, so verify current numbers on each pricing page before committing.
For this comparison, we looked at each vendor's documented plans, credits, and limits, plus the patterns reviewers consistently report. HeyGen documents a free plan, Creator at $29 per month ($24 billed annually), Pro from $49, and Business at $149 plus $20 per seat. Synthesia documents a free Basic plan, Starter at $29 per month ($18 billed yearly), and Pro at $89 per month ($64 yearly), with Enterprise on custom pricing.
How We Compared These AI Video Platforms
We compared HeyGen and Synthesia using their public pricing pages, documented feature lists, and consistent themes in published reviews. We did not generate videos in either platform, so nothing here is a judgment of avatar realism or render speed, which are subjective and change with each model release. We applied one yardstick to both: what the free plan allows, what each paid tier costs and includes, how credits relate to minutes of video, the language and avatar options, and which team and compliance features are documented.
HeyGen and Synthesia Pricing and Credits Compared
HeyGen's free plan is documented at 3 videos a month, up to 1 minute each, exported up to 1080p, with 1 custom avatar. Creator adds 600 monthly credits, videos up to 30 minutes, voice cloning, translation across 175+ languages and dialects, and watermark removal. Pro starts at 1,000 credits with 4K export and access to advanced AI models, with larger credit tiers available at higher prices. Business adds 5+ custom avatars, SAML single sign-on, SCORM export, and LMS integrations.
Synthesia's free Basic plan is documented with 500 credits, 9 stock avatars, and a watermark. Starter adds downloads and logo removal, 125+ stock avatars, and 3 personal avatars; Pro adds 180+ stock avatars, 5 personal avatars, interactive videos, branded video pages, and priority support. The vendor's own figures suggest roughly 12 minutes of video a month on monthly Starter and about 60 on monthly Pro, though it says these are estimates that depend on avatars, motion graphics, and dubbing.

Where HeyGen Wins: Flexibility, Translation, and Entry Price
HeyGen's documented strengths are breadth and price. Creator lets you produce videos up to 30 minutes, clone a voice, and translate into a wide set of languages at a monthly price comparable to Synthesia's Starter, and the documented rollover of unused credits for one extra month softens the credit model. Reviewers consistently highlight its video translation with lip-sync as a standout, which suits marketers localizing the same ad or explainer. The free plan is also enough to try the core experience.
The limits are worth noting. Credits are a single currency spent across features, and usage per video varies by model, duration, and complexity, so the cost per finished minute is not fixed. Upgrading is prorated but downgrades take effect at the end of the cycle, and after cancelation unused credits do not carry over. Business-grade controls only appear at the $149 tier plus per-seat fees.
Where Synthesia Wins: Training Content and Governance
Synthesia positions itself around corporate training, onboarding, and internal communication. Its documented extras include learner seats for role-play training, survey responses with analytics, interactive videos on Pro, and on Enterprise SAML single sign-on, SCORM export, brand kits, live collaboration, and a dedicated customer success manager. For an HR or learning team publishing many structured videos that must meet security reviews, that set of documented features is the clearest reason to choose it.
The costs and caveats are also clear. Entry plans cap editors at one, extra capabilities such as the Studio Express-1 avatars are a paid add-on at $1,000 a year for annual plan users, and the vendor's own page lists some inconsistent credit figures on the yearly Starter tier, which is a reason to confirm the numbers before buying. Its free Basic plan carries a watermark and is mainly a trial.
Which AI Video Platform Fits Your Team
Pick HeyGen for marketing videos, sales outreach, social content, and localization, especially if you are a solo creator or a small team that wants the lowest practical entry cost and long-video allowances. Pick Synthesia for training libraries, compliance content, and enterprise rollouts where SCORM, single sign-on, and a managed relationship are requirements. If you only need occasional videos, test the free plans on both and see whether the avatar style suits your audience.
Be realistic about the category too. AI avatar video can look uncanny to some viewers, and disclosure rules around synthetic media are evolving, so review what your audience and platform policies expect. Our best AI tools for small business guide places video generation alongside writing and automation tools if you are still deciding where to invest first.
The bottom line: choose HeyGen for flexible, affordable marketing and translation videos, and choose Synthesia when training content, governance, and enterprise controls are what you are buying.
