Synthesia

Synthesia is the most established enterprise AI video platform. The core workflow: pick or create an avatar, write or paste a script, choose a voice and language, hit generate, and a fully edited talking-head video — with backgrounds, lower-thirds, screen recordings, and B-roll — is rendered in minutes. The current Synthesia 3 / Express-2 model line has materially improved lip sync, body motion, and emotional range, with Personal Avatars that learn from a short consented webcam recording so an internal trainer or salesperson can appear without standing in front of a camera. The platform covers 230+ stock avatars, 140+ languages and accents, AI voice cloning, real-time translation of an existing video into other languages, screen recorder, video templates, brand kits, an AI assistant that converts PDFs, slides, or URLs into a script and storyboard, and an API for high-volume programmatic production. Synthesia is heavily used in corporate Learning & Development (training videos), internal communications, sales enablement, and how-to content.
