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 by a team of Oxford, Stanford, and Cambridge researchers, Synthesia has spent years building enterprise trust. By April 2026, over 55,000 companies — including Heineken, BSH Group, and Teleperformance — use Synthesia 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, SOC 2 compliance, team collaboration workflows, and a PowerPoint add-in.

Key Features

• 230+ AI Avatars: A diverse library of professional-looking avatars across multiple ethnicities, ages, and presentation styles, all validated for inclusive corporate use.
• Personal Avatar Creation: Record a 5-minute green-screen video of yourself, and Synthesia creates an AI avatar trained on your appearance and voice.
• 140+ Languages: Automatically translate and re-voice your video into 140+ languages. The same avatar speaks each language with appropriate accent and lip-sync.
• PowerPoint Integration: A native add-in lets you convert your PowerPoint slides into video presentations with AI narrators — no video editing required.
• SCORM Export: Generated videos can be exported as SCORM packages for direct integration into LMS platforms like Workday Learning, Cornerstone, or SAP SuccessFactors.
• Template Library: 60+ professionally designed templates for specific use cases (product demo, employee onboarding, how-to guide, etc.).
• Screen Recording: Combine AI avatar videos with screen recordings for software training and walkthroughs.
• Brand Kit: Custom brand colors, logo placement, and font integration across all videos.

How It Works

1. Script: Type or paste your script (or use the AI Script Assistant to generate one from a topic).
2. Avatar: Select from the avatar library or use your personal avatar.
3. Template: Choose a layout and customize colors/branding.
4. Generate: Synthesia renders the video in a few minutes.
5. Translate: Click "Add Language" to generate additional language versions automatically.

Technical Architecture:

3. Type your script in the left panel.

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.

Pricing & Plans

• Starter (~$22/month): 120 minutes of video/year, 90+ avatars, 140 languages, PowerPoint add-in.
• Creator (~$67/month): 360 minutes/year, personal avatar, custom brand kit, priority support.
• Enterprise: Custom pricing — unlimited video minutes, SSO, SCORM, advanced analytics, API, dedicated CSM.

Note: Synthesia pricing is based on video minutes generated per year, not credits.

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: Per-minute pricing can become expensive for high-volume production (Enterprise plan resolves this).
• Script Dependency: Avatars can only deliver pre-written scripts — no real-time interactivity in standard mode.
