What Is Synthesia?
Synthesia is an AI video communications platform that turns scripts, documents, presentations, prompts, and other source material into videos using AI avatars, voices, generated media, translation, dubbing, and interactive elements.
Its strongest positioning is business communication at scale. Typical use cases include employee training, onboarding, learning and development, sales enablement, standard operating procedures, internal communications, product explainers, and multilingual knowledge content.
What Is HeyGen?
HeyGen is an AI video creation platform for generating avatar-led videos, translating and localizing existing content, cloning voices, creating custom avatars, and producing video without a traditional camera crew.
HeyGen is used across marketing, social content, sales, learning and development, and personalized video. Its newer plans emphasize Avatar IV, large avatar libraries, multilingual creation, higher-resolution exports, team collaboration, and integrations with automation and business tools.
Synthesia vs HeyGen Pricing in 2026
Both platforms now have accessible free plans and a $29 monthly paid entry point, but their usage models are different. Synthesia measures self-serve usage through a shared credit pool tied to video, dubbing, and generated assets. HeyGen also uses credits on paid plans while setting separate maximum video lengths and export capabilities by tier.
| Platform / Plan | Current monthly price | Key current limits / features |
|---|---|---|
| Synthesia Basic | $0 | 1,200 credits/month, up to 10 minutes of video, 9 AI avatars |
| Synthesia Starter | $29 | 1,200 credits/month, up to 10 minutes of video, 125+ avatars, downloads, AI Video Assistant, AI dubbing |

Free Plans Compared
Synthesia Basic provides 1,200 credits per month, which currently corresponds to up to 10 minutes of generated video, along with a limited avatar set. It is useful for exploring the editor and testing the workflow before paying.
HeyGen Free allows three videos per month, each up to one minute, and includes access to Avatar IV, more than 500 stock video avatars, one custom video avatar, and support for more than 30 languages. The limits are tighter by duration but provide a practical way to test HeyGen’s avatar quality and interface.
AI Avatars
Synthesia offers a large stock avatar library that expands by plan, from a small Basic selection to 240+ stock AI avatars on Enterprise. Paid plans also support Personal Avatars, allowing teams to create digital versions of real people with consent.
HeyGen currently advertises more than 500 stock video avatars and places strong emphasis on Avatar IV, Photo Avatars, and custom video avatars. For teams that prioritize a wide visual range and creator-style avatar output, HeyGen’s avatar catalog is a major attraction.
Personal and Custom Avatars
Synthesia Starter currently includes three Personal Avatars, Creator includes five, and Enterprise supports unlimited Personal Avatars subject to reasonable usage policies. Personal Avatars can be created from approved photo or video workflows with consent requirements.
HeyGen includes custom-avatar capabilities across its plan structure, with Free including one custom video avatar and Business including five. Creator and Pro also provide unlimited Photo Avatars under current packaging.
Languages, Voice Cloning, and Localization
Synthesia supports AI video creation across 160+ languages and has a large voice library. Its localization tools include one-click translation, AI dubbing, lip-sync, voice cloning, and a multilingual video player that can serve content in a viewer’s preferred language.
HeyGen Creator and higher currently support 175+ languages and dialects and include voice cloning. HeyGen also provides dedicated video-translation tools that can adapt existing content into additional languages while preserving speaker identity and synchronizing the result.
If voice generation is a bigger priority than avatar video, compare our ElevenLabs vs Murf 2026 guide for a closer look at AI voice platforms.
Video Quality and Export Resolution
HeyGen makes resolution differences easy to understand in its current plan structure: Creator exports at 1080p, while Pro, Business, and Enterprise support 4K export.
Synthesia focuses less on headline resolution tiers and more on business production workflows, localization, avatars, interactivity, and collaboration. Teams should verify the current export settings available on the plan they are evaluating if resolution is a purchasing requirement.
AI Video Generation Workflow
Synthesia can turn a script, prompt, document, PowerPoint, or link into a structured video. Teams can combine avatars, AI voices, generated visuals, media, animations, quizzes, calls to action, and branching interactions.
HeyGen provides a fast creator-oriented workflow that can start from text or templates and produce avatar video with generated speech, custom avatars, translations, and other AI-assisted media. Its current higher tiers also unlock additional advanced AI models.
AI Dubbing and Video Translation
Synthesia’s AI Dubbing can localize existing videos into more than 140 languages while preserving speaker voices and using lip-sync. Its current credit model lets customers allocate usage between video generation, dubbing, and AI-generated media.
HeyGen also makes video translation a core part of its platform. Creator includes multilingual creation and voice cloning, while higher tiers add stronger translation controls, processing speed, and enterprise workflow options.
Interactivity and Learning Content
Synthesia is particularly strong for structured learning content because it supports interactive videos with quizzes, calls to action, and branching. Its broader product also includes Roleplay Sessions for AI-assisted practice and coaching use cases.
HeyGen Business includes Interactive Video features such as quizzes and links, along with SCORM export and LMS integrations. That makes HeyGen increasingly relevant for learning teams even though its broader market positioning remains more creator- and marketing-friendly.
Team Collaboration
Synthesia Starter includes one editor and three guests, while Creator includes one editor and five guests. Guests can view and comment, and Enterprise expands into more advanced workspaces, roles, permissions, and organization-level collaboration.
HeyGen Business adds workspace collaboration, video draft commenting and editing, team management, centralized billing, and SAML/SSO. Enterprise expands the control model further with multiple workspaces, role management, SCIM provisioning, and enterprise support.
API and Automation
Synthesia provides multiple APIs. Its Video API supports scripted video generation, dubbing, translation, and template-driven production, while the Interactive Avatars API enables real-time avatar experiences. Current availability depends on plan: the legacy Video API is available on Creator and Enterprise, while Interactive Avatars API access is broader.
HeyGen offers a separate pay-as-you-go API for generating video, translating video, text-to-speech, avatars, templates, and other programmatic workflows. This separation can be attractive to developers who want API usage without tying every automation to a standard creator subscription.
Integrations
Synthesia supports integrations and workflow connections for business video production, including API-driven creation and automation integrations such as Zapier.
HeyGen Business currently advertises integrations with tools including n8n, Make, HubSpot, and Zapier, which fits teams building AI video into broader marketing, sales, or automation workflows.
Enterprise Security and Governance
Synthesia’s enterprise positioning is one of its strongest differentiators. Enterprise plans are built around larger organizations with shared workspaces, organization controls, SSO, expanded avatar access, higher API capacity, brand governance, and large-scale video production.
HeyGen Business already includes SAML/SSO, while Enterprise adds multi-workspace control, SCIM provisioning, MFA, centralized role management, tailored onboarding, and enterprise support. Both platforms therefore have credible enterprise paths, but Synthesia’s product identity is more deeply rooted in large-company training and business communications.

Synthesia vs HeyGen for Training and L&D
Synthesia has a strong advantage in dedicated business-learning workflows. Interactive video, roleplay, enterprise workspaces, localization, and structured internal-content production make it particularly well suited to L&D and enablement teams.
HeyGen Business is also increasingly capable for learning workflows thanks to interactive video, SCORM export, LMS integrations, translation, and collaboration. It may be especially attractive when the same team also creates marketing or external-facing content.
Synthesia vs HeyGen for Marketing and Social Video
HeyGen is generally the more natural fit for fast marketing and creator workflows because of its avatar variety, 1080p and 4K tiers, translation, custom avatars, and lower-cost Creator plan.
Synthesia can absolutely produce marketing and explainer content, but its strongest differentiation is structured business video rather than fast-moving creator output.
Synthesia vs HeyGen for Global Localization
Both platforms are highly competitive for localization. Synthesia combines 160+ language support, AI dubbing, voice cloning, one-click translation, and multilingual playback. HeyGen supports 175+ languages and dialects on Creator and higher and provides dedicated translation workflows.
The decision should therefore depend less on raw language count and more on workflow: Synthesia fits structured enterprise localization, while HeyGen is compelling for fast creator, marketing, and sales localization.
