Synthesia

Synthesia is the enterprise standard for AI avatar video. While HeyGen is the go-to for marketing teams and social creators, Synthesia has won the corporate market — specifically L&D (Learning & Development), HR, and internal communications teams who need professional, consistent, on-brand training videos at scale across global organizations.

Overview

Founded in 2017, Synthesia has spent years building enterprise trust. Synthesia states it is used by over 50,000 companies — Heineken among them — to replace costly studio video production with AI-generated presenter content.

The core product is straightforward: type a script, choose an AI avatar (or create your own), select a template, and Synthesia generates a professional video in minutes. What differentiates Synthesia from competitors is its focus on enterprise requirements — SCORM export for LMS platforms (an Enterprise-plan feature), SOC 2 Type II and ISO 42001 compliance, and team collaboration workflows.

Key Features

• Up to 240+ AI Avatars: The stock avatar library scales with plan — 9 avatars on the free Basic plan, 125+ on Starter, 180+ on Creator, and the full 240+ selection on Enterprise.
• Personal Avatar Creation: Create your own digital twin. Starter includes 3 personal avatars, Creator 5, and Enterprise unlimited. Higher-fidelity Studio Express-1 avatars are a paid add-on ($1,000/year, annual plans only) and take up to 10 days to process.
• 160+ Languages and Voices: Every plan gets access to over 160 languages and voices, including narration styles and local accents. AI Dubbing output is narrower: 70+ languages on Basic/Starter/Creator, 140+ on Enterprise.
• 1-Click Translation: Translate an entire Synthesia video into other languages in one click. Enterprise covers 80+ languages.
• SCORM Export: Videos can be exported as SCORM packages for LMS platforms — an Enterprise-plan feature.
• Screen Recording: Combine AI avatar videos with screen recordings for software training and walkthroughs.
• Interactivity & Video Agents: Interactive videos and interactive avatars, with Video Agents listed as coming soon.
• Brand Kit: Custom brand colors, logo placement, and font integration across all videos.
• 1000+ AI Voices and voice cloning to pair with a custom avatar.

Best Practices

• Keep videos under 5 minutes: Viewer retention drops significantly beyond 5 minutes for training content.
• One topic per video: Shorter, focused videos are more rewatchable and easier to update.
• Use the Script Assistant: Synthesia's built-in AI writes structured, engaging scripts from topic prompts.
• Record Personal Avatar professionally: Lighting quality in your recording directly determines avatar quality.

Limitations

• Presenter-Only Videos: Designed for talking-head style presenter videos — not for cinematic storytelling or complex scene generation.
• Avatar Realism: While improving, Synthesia's avatars can still look slightly artificial in high-scrutiny contexts like C-suite communications.
• Cost at Scale: The Starter and Creator plans cap output at 10 and 30 minutes of video per month respectively. Unlimited minutes require the Enterprise plan.
• Feature Gating: SCORM export and the full 240+ avatar library are Enterprise-only. API access starts at Creator. The Basic plan cannot download videos at all.
• Script Dependency: Standard avatars deliver pre-written scripts; interactive avatars are a separate beta feature.
