Synthesia revolutionizes video production by eliminating the need for cameras, studios, and actors. You type or paste a script, choose an AI avatar from a diverse library (or create a custom avatar of yourself), select a voice, and Synthesia generates a professional video with the avatar speaking your words with realistic lip-sync and expressions. The platform supports 120+ languages and accents, making it perfect for creating localized content at scale. Beyond avatars, Synthesia offers templates for various use cases, screen recording, media library, and collaboration features. It's particularly popular for corporate training videos, product explainers, how-to content, and internal communications. By reducing video production from days to minutes, Synthesia makes professional video accessible to organizations of all sizes.
