Overview
Synthesia is an AI video platform for business that lets teams create studio-quality videos with AI avatars and voiceovers in 140+ languages. It supports generating videos from scripts, PowerPoints, documents, or links, and offers interactive Sessions for roleplay practice and conversational surveys. The platform is designed for enterprises, trusted by 90% of the Fortune 100, and includes APIs for programmatic video generation and real-time interactive avatars.
How it works
Synthesia generates videos from a script, PowerPoint, document, or URL using an AI Assistant that produces a draft with scenes and an avatar presenter. Users can choose from hundreds of stock avatars, design custom avatars with Avatar Builder, or create a Personal Avatar from a photo or video with a live consent recording. Videos can be translated into 140+ languages with 1-Click Translation or dubbed with AI Dubbing, preserving the original voice and lip sync.
Key capabilities
The platform includes Roleplay Sessions where avatars push back during practice conversations and provide coaching and scoring, and Survey Sessions that ask questions, follow up, and summarize themes and sentiment. Interactive Avatars can be embedded in products for real-time customer support or training. The API allows programmatic video generation, dubbing, and avatar streaming, with an MCP server for use inside Claude or ChatGPT.
