Methodology
Official pricing and product documentation were checked on September 6, 2026. The comparison covers published workflow, free-plan access, usage limits, collaboration, and intended use. It does not assign an unsupported score for avatar or lip-sync quality.

The practical difference
Synthesia presents a structured business-video workflow with templates, scripts, files, PowerPoint imports, avatars, dubbing, and team-oriented controls. HeyGen presents avatar creation, translation, and creator-oriented video generation with plan limits that can vary by region and product mode.
The correct choice depends on the production job. Training and repeatable internal communication have different requirements from short marketing videos or translated creator content.
What the free plans can establish
Synthesia's Basic plan publicly lists a monthly credit allowance and up to ten minutes of video, while downloads and logo removal are paid-plan features. Its documentation also states that template, PowerPoint, blank-canvas, and dubbing starting points are available on the free plan, while some Assistant-driven imports require payment.
HeyGen's official help documentation describes free generation limits as region-dependent. A comparison should therefore record the allowance displayed in the actual account rather than presenting one universal free quota.
How to test both fairly
Use the same four-scene script, the same target language, similar stock-avatar framing, and the same 1080p requirement. Record setup time, available voices, pronunciation controls, subtitle editing, translation steps, generation time, visible branding, and export restrictions.
A second test should change only the target language. This separates localization workflow from differences caused by script length, scene design, or avatar choice.
Cost questions that matter
Compare the lowest plan that permits the required export, the included video minutes or credits, editor and guest access, and any limits on avatars, translation, or generated assets. Avoid converting credits into a universal price-per-video unless the exact workflow and current credit rules are documented.
Enterprise features and negotiated pricing should be treated separately from self-service plans. They are not directly comparable to fixed monthly prices without a real quotation.
Current editorial conclusion
Synthesia is the clearer research shortlist for structured training, presentations, and team video production. HeyGen remains an important comparison candidate for creator videos and translation workflows.
This conclusion is a workflow-fit assessment from official documentation. For a final quality decision, test both platforms with the same script, target language, scene count, and export requirement.
