Synthesia

Learning Objectives

• Understand what Synthesia is and how it positions in the AI avatar video market
• Learn the core features that make Synthesia the choice for enterprise L&D and training teams
• Distinguish Synthesia's strengths versus HeyGen and other avatar video tools

What Is Synthesia?

Synthesia is a London-based AI video platform founded in 2017, making it one of the oldest companies in the AI video space. Synthesia's focus is squarely on enterprise learning and development (L&D), corporate training, and internal communications — the use case of producing professional, multilingual presenter-style videos at scale for large organizations.

While HeyGen and Synthesia serve overlapping audiences (AI avatar video for business), Synthesia has historically focused more on depth of enterprise features — SCORM/LMS integration, compliance workflows, and breadth of supported languages — rather than consumer-facing viral growth.

Pricing

Read the allowances carefully — the paid tiers are budgeted per YEAR, not per month. Starter's 120 minutes is an annual figure, so it works out to about ten minutes a month; a team that reads it as monthly will overestimate its capacity roughly twelvefold. Pricing is denominated in credits, and the headline monthly prices above are the billed-yearly rates — month-to-month costs $29 and $89 respectively.

The free Basic plan is a real plan rather than a time-limited trial, which makes Synthesia unusually cheap to evaluate properly against a real training script.

Synthesia's Enterprise tier is where its differentiation is strongest — SCORM export for LMS integration, SSO for corporate identity management, and data processing agreements for regulated industries like financial services and healthcare.

Core Capabilities

AI Avatar Library

Synthesia offers a large library of diverse professional AI avatars — reaching 240 or more on Enterprise, 180 or more on Creator — covering a wide range of ages, ethnicities, attire, and presentation styles. Avatars are designed specifically to look appropriate in a business context — more polished and professional than the broad avatar libraries found in general-purpose tools.

Language Support Across 160+ Languages

Synthesia supports video generation in more than 160 languages and accents, available on every plan including the free one. For global organizations running training programs across multiple markets, that breadth removes the need for per-language recording sessions entirely.

Worth being precise about where this sits competitively, because it is easy to overstate: 160-plus is broad but no longer category-leading — HeyGen now covers more than 175. Treat language count as table stakes among the serious enterprise tools rather than as the reason to choose one. Synthesia's real separation is on the enterprise side: SCORM and AICC export, compliance workflows, and data processing agreements. Note also that Enterprise one-click translation covers 80 or more languages, a narrower set than the generation figure — if translating existing footage is the actual job, check that number rather than the headline.

Template-Based Editor

Synthesia provides a drag-and-drop video editor with professional templates — combining AI avatars with slides, screen recordings, images, text overlays, and branded elements. The editor is designed for people without video production experience; L&D managers, HR teams, and subject-matter experts can produce polished videos without any editing software knowledge.

SCORM and LMS Integration

A key enterprise feature: Synthesia videos can be exported as SCORM or AICC packages — the standard formats for deploying interactive content in Learning Management Systems (LMS) like Workday Learning, Cornerstone, and SAP SuccessFactors. This makes Synthesia the natural choice for organizations already operating LMS-based training infrastructure.

Custom Avatar Cloning

Personal AI avatars — a digital version of yourself or a designated company presenter, built from a short recording session — start on Starter, which includes three, rather than being gated to the top tiers. Creator includes five and Enterprise is unlimited. The custom avatar can then produce video content without requiring that person's availability.

Screen Recording + AI Presenter

Combine a screen recording (software demo, product walkthrough) with an AI presenter in a split-screen or overlay format — producing professional instructional content in a format learners find more engaging than screencasts alone.

Strengths

• Broad language support — 160+ languages on every plan, including the free one; competitive with the category leaders rather than ahead of them
• Enterprise-grade compliance — SCORM export, AICC, SSO, SLA, and data processing agreements for regulated industries
• L&D-specific design — templates, workflows, and LMS integration built specifically for training content
• Established track record — one of the oldest AI video companies; used by Zoom, Heineken, Reuters, and thousands of enterprise customers
• Non-technical audience focus — editor designed for subject-matter experts and L&D managers, not video production teams

Limitations & Considerations

• Annual credit budgets, not monthly minutes — paid allowances are granted per year, so Starter's 120 minutes is roughly ten minutes a month; high-volume training programs need Enterprise pricing
• Less competitive for cinematic or creative content — Synthesia is purpose-built for business explainer video; it is not suitable for cinematic, artistic, or social media creative content
• Avatar naturalness — stock avatars are polished and professional but can appear slightly artificial in emotional or casual contexts compared to realistic custom avatar clones
• Custom avatar quality depends on recording — the personalized avatar requires a clean, controlled recording environment to produce convincing results

Best Use Cases

When to choose alternatives:

• Consumer or social media video → Sora 2, Runway ML, or Pika Labs
• Lip-sync video translation of existing footage → HeyGen (stronger translation feature)
• AI video editing (cutting, overdub) → Descript
• Cinematic or artistic video generation → Veo 3 or Runway ML

Getting Started

1. Go to synthesia.io and create a free account
2. Click Create Video → choose a template or start from blank
3. Select an AI avatar from the library
4. Enter your script in the text panel — Synthesia's AI generates the voiceover and lip-sync
5. Add slides, images, or screen recording to complement the presenter
6. Set the language and export the video; on Enterprise, export as SCORM for LMS deployment

Key Takeaways

• Synthesia is the leading enterprise platform for AI avatar video in corporate training, with 160+ language support and SCORM/LMS integration that competitors do not match
• It is purpose-built for L&D, HR, and internal communications teams — not a general-purpose video or cinematic content tool
• The SCORM export and data processing agreements make it particularly valuable for large, regulated organizations deploying training at scale
• HeyGen is a stronger choice for video translation of existing footage, and now covers more languages besides (175+ against 160+) — so do not choose Synthesia on language count; its durable advantage is enterprise infrastructure built in from the ground up: SCORM and AICC export, compliance workflows, SSO, and data processing agreements
• Paid allowances are annual rather than monthly, which is the single most misread thing about its pricing
