Synthesia Review
Create professional AI videos with 140+ avatars in 120+ languages. No filming equipment needed.
Our Review
Synthesia is the enterprise choice for AI avatar video creation, used by over 50,000 companies including Amazon and Zoom. The avatars are among the most realistic in the industry, and the platform offers robust features for corporate training, compliance videos, and product demonstrations. After creating corporate training modules, we found it significantly more professional-looking than HeyGen for business contexts.
How to Use Synthesia
Getting Started with Synthesia
Visit synthesia.io to create a trial video. Choose from 140+ AI avatars, select a template, and type your script. Synthesia's templates are organized by use case: training videos, product demos, onboarding content, and compliance communications. Start with a simple template to understand the platform's workflow.
Creating Professional Training Videos
For corporate training, use Synthesia's slide-based template. Upload your presentation slides, add narration text for each slide, and choose a professional-looking avatar. The avatar reads your script with natural lip sync and body language. Add on-screen text, images, and your company logo for brand consistency.
Multilingual Content Creation
Synthesia's 120+ language support makes it ideal for multinational organizations. Create a training video once in English, then duplicate the project and translate the script to other languages. The avatar speaks each language naturally, making it possible to produce localized content at scale without hiring voice actors.
Best Practices
Keep scripts concise — avatars look most natural with sentences of 15-25 words. Use the pause feature between sections for natural pacing. For compliance and legal content, review the output carefully for accurate pronunciation of technical terms. Consider adding subtitles for accessibility and better information retention.
