Synthesia is a web-based platform that turns text scripts into videos narrated by AI avatars, aimed at corporate training, sales enablement, and marketing use cases rather than open-ended cinematic generation. It offers stock and custom AI avatars, AI voiceover in 160+ languages, one-click video translation/dubbing into 140+ languages, and a separate AI Playground for prompt-based video/image generation using third-party models (Veo 3.1, Gemini Omni). A free Basic plan exists alongside paid Starter, Creator, and Enterprise tiers.
Businesses and teams producing training, sales-enablement, marketing, and internal-communications videos who want to avoid filming with cameras, actors, or studios.
A web editor for building avatar-led videos from text scripts, files, or URLs; a library of 240+ stock avatars plus personal/custom avatar creation; AI voiceover and dubbing into 140+ languages with lip-sync; and an AI Playground for generating video/image assets with third-party models like Veo 3.1 and Gemini Omni.
A user types or uploads a script, picks an AI avatar and voice, and Synthesia renders a video with synchronized speech and lip movement; videos can be translated/dubbed into other languages in one click, and separately, the AI Playground can generate short video clips from a text prompt or an uploaded start/end frame image.
