HeyGen vs Synthesia: what each does better and how to choose

Updated August 25, 2026 to reflect current pricing, credit usage, dubbing, and SCORM availability.

HeyGen vs Synthesia is the comparison most people start with when evaluating AI avatar video platforms. Both turn a script into a video of a digital person speaking it. Both support multiple languages. Both offer custom avatar creation from recorded footage. Both start at $29/month.

The difference is in what each platform was built for. Synthesia optimized for enterprise L&D teams producing training content at scale, with compliance tooling and SCORM export baked in. HeyGen built for a wider market, with a larger template library, stronger video translation features, and a separate real-time product for conversational use cases.

This comparison covers what each platform does well, where each falls short, how pricing actually works, and when you should pick one over the other.

What does HeyGen do well?

HeyGen started as a video translation and avatar creation tool and has expanded into one of the broadest AI video platforms on the market.

Video translation. HeyGen can dub existing footage with lip sync, and its paid plans list 175+ languages and dialects. Synthesia now offers the same core workflow for uploaded files and YouTube links, with voice preservation and lip sync in 140+ languages. HeyGen still has a broader published language range, but the feature is no longer exclusive.

Templates and creative tools. HeyGen has more pre-built video templates than most avatar platforms. For marketing teams producing social clips, product videos, or ads on a tight cycle, the template library cuts production time. The editor supports scene-level control over backgrounds, text overlays, and transitions.

Broader integration surface. HeyGen connects with Zapier, HubSpot, and various video hosting platforms. For teams that need avatar video plugged into an existing marketing or content stack, the number of native integrations is wider than what Synthesia offers.

Interactive Avatar product. HeyGen has a separate real-time product (Interactive Avatar, at liveavatar.com) that supports live conversational avatar experiences. This gives HeyGen a foot in both the pre-rendered and real-time categories, though the real-time product is architecturally separate from the video creation studio.

Where HeyGen is weaker: Credit usage varies sharply by model, so costs need a little math. Avatar III costs 3 credits per minute, while Avatar IV and V cost 20. Governance features sit on Business ($149/month) and Enterprise at custom pricing. Business also includes SCORM export and LMS integrations, so the old no-SCORM claim is out of date.

What does Synthesia do well?

Synthesia is the longest-established name in AI avatar video and the default choice for large enterprise L&D teams.

Enterprise compliance and governance. Synthesia puts SCORM export, SAML SSO, audit trails, workspace permissions, and its broader governance controls on Enterprise at custom pricing. If your training team needs to publish avatar content to an LMS such as Cornerstone, Workday, or Docebo, that is the tier to evaluate.

Training-focused editor. Synthesia’s Creator tier ($89/month) includes interactive video and branching. Quizzes and SCORM export require Enterprise at custom pricing. HeyGen offers comparable interactive tools on Business ($149/month).

Generous free tier. Synthesia’s free plan gives 10 minutes of video per month with 9 avatars and a functional editor. Videos carry a Synthesia watermark, but the time allowance is far more generous than HeyGen’s 3 watermarked videos. For evaluation purposes, Synthesia lets you test more thoroughly before committing money.

Language breadth. Synthesia lists 160+ creation languages and dubbing in 140+ languages. HeyGen lists 175+ languages and dialects on paid plans. Both have broad localization coverage; HeyGen has the larger published paid-plan range.

Avatar library at lower tiers. At the Starter tier ($29/month), Synthesia gives access to 125+ avatars. HeyGen offers 700+ stock avatars on paid plans, but many of the higher-quality options require more credits per minute, so the effective selection depends on your budget per video.

Where Synthesia is weaker: Fewer marketing templates and less emphasis on social-video workflows. No general-purpose real-time conversational product alongside the main studio. API access requires Creator at $89/month. AI dubbing is now a strength, though, with uploaded-file and YouTube dubbing, voice preservation, and lip sync in 140+ languages.

How do HeyGen vs Synthesia features compare side by side?

For deeper dives on each platform individually, see the HeyGen API and feature review and the broader AI avatar generators comparison. There’s also a separate Tavus vs Synthesia comparison if you’re evaluating across more platforms.

How does pricing actually compare?

Both platforms now use shared credits, but the units are not interchangeable. HeyGen charges 3 credits per minute for Avatar III and 20 for Avatar IV or V. Synthesia Starter ($29/month) includes 1,200 credits, usable for up to 10 minutes of video or dubbing, while Creator ($89/month) includes 3,600 credits for up to 30 minutes.

The HeyGen credit math to watch. Avatar III costs 3 credits per minute; Avatar IV and V cost 20. Creator ($29/month) includes 600 credits, enough for about 200 minutes of Avatar III or 30 minutes of Avatar IV or V. Full lip-synced translation costs 5 credits per minute. Check the model and workflow before turning a credit balance into a minute estimate.

Synthesia’s tier jump. Starter is $29 for 1,200 credits, usable for up to 10 minutes. Creator is $89 for 3,600 credits, usable for up to 30 minutes. If you need a middle price point, Colossyan Professional is $89/month, or $59/month with annual billing, with separate allowances of 30 NEO and 10 NEO2 minutes.

At $29/month, Synthesia Starter provides up to 10 minutes from its credit pool. HeyGen Creator provides 600 credits, which can mean about 200 Avatar III minutes or 30 Avatar IV or V minutes. HeyGen offers more output when you stay within those avatar models, while Synthesia’s allowance is simpler to read.

Annual billing. Both platforms offer discounts for annual commitment, typically 20-40% off monthly pricing. If you’re committing to either platform, annual billing changes the per-minute economics significantly. But don’t lock in annually until you’ve produced at least a month of content and confirmed the platform fits your workflow.

When should you pick HeyGen? When should you pick Synthesia?

Pick HeyGen if:

• You prefer HeyGen’s 175-language localization workflow and flexible translation credits.

• You’re producing marketing, social, or creative content where templates and visual flexibility matter.

• You want the option to explore real-time interactive avatars alongside pre-rendered video from the same vendor.

• You have variable usage patterns that benefit from a credit system over fixed minutes.

Pick Synthesia if:

• Your primary use case is corporate training and you need SCORM export, LMS integration, and compliance tooling.

• You’re in a regulated industry that requires SSO, audit trails, and enterprise governance.

• Language breadth matters and you need 160+ languages, including less common pairs.

• You want the most generous free evaluation experience (10 min, functional editor, more avatars than HeyGen’s free tier).

Pick neither if the use case is two-way conversation. Both HeyGen (standard product) and Synthesia generate scripted, pre-rendered video. If a user needs to talk back to the avatar, ask questions, or have an unscripted interaction, that’s a structurally different category. The split between content avatars and conversation avatars is the most important distinction in this market, and it determines which platforms are even in your consideration set.

If you need both scripted video and conversation, evaluate the categories separately. Buying a pre-rendered platform hoping it will eventually add real-time conversation (or vice versa) usually leads to disappointment. The architectures are different enough that doing both well from a single codebase is genuinely hard. Most teams that need both end up with one vendor for content production and a separate one for conversational deployment.

What if you need real-time conversation instead of scripted video?

Both HeyGen and Synthesia are primarily pre-rendered platforms. If your actual need is a live AI agent that holds a conversation, you’re evaluating a different product category.

Real-time interactive avatars generate every frame live during a conversation. The user speaks, the avatar listens, a language model processes the input, and the avatar responds with synchronized face, voice, and expressions in real time. No script. No rendered file. This is what customer support, onboarding, sales qualification, and training simulation use cases need.

HeyGen’s Interactive Avatar product extends its platform into real-time, though it’s a separate product from the standard video studio. Anam’s Cara model is purpose-built for real-time interactive avatar conversation with sub-900ms latency. Tavus is another option with strong developer tooling.

An independent 178-participant blind study at avatarbenchmark.com compared avatar platforms on realism, responsiveness, and interruptibility across real-time conversation. If you’re evaluating the conversational category, that benchmark is a useful starting point.

Can I create a custom avatar of myself on both platforms?

Yes. Both platforms support custom avatar creation from 2-5 minutes of recorded video. Quality depends on source footage lighting, framing, and audio clarity. Both also offer large libraries of stock avatars if you don’t need a custom likeness. Check each platform’s recording guidelines before shooting, as the requirements differ slightly.

Does HeyGen or Synthesia offer SCORM export?

Both do. Synthesia supports SCORM export on Enterprise at custom pricing. HeyGen includes SCORM export and LMS integrations on Business at $149/month. HeyGen no longer lacks native SCORM.

Which platform is better for marketing content?

HeyGen. Its template library and creative editing tools fit marketing workflows, and paid plans cover 175+ languages and dialects. Synthesia now has capable AI dubbing too, so the decision is more about templates, collaboration, and governance than a missing localization feature.

Is there a real-time conversational avatar option?

Synthesia is pre-rendered only. HeyGen has a separate product called Interactive Avatar for real-time conversation. For purpose-built real-time interactive avatars, Anam and Tavus are designed specifically for conversational use cases.
