Synthesia

Synthesia lets you make studio-quality videos without a camera, actor, or microphone. You type a script, pick an AI avatar and voice, and get a polished video in minutes, complete with templates, branding, and screen recording.

It is widely used for training, onboarding, product explainers, and localized marketing at enterprise scale. Because updates are as simple as editing text, teams can keep video content current without reshoots.
