Synthesia

Synthesia is an AI video generation platform that creates videos using AI avatars that deliver spoken content from a text script. Users write a script, select an AI avatar and voice, and the platform generates a professional-quality talking-head video without cameras, actors, or studio equipment. Founded in 2017 and headquartered in London, Synthesia is primarily used by enterprise learning and development teams, corporate communications departments, and marketing organisations that need to produce video content at scale without the traditional production overhead. It is one of the most established platforms in the AI video avatar market, offering over 100 AI avatars and supporting 120+ languages, making it particularly relevant for multilingual training and communication content.

How it works

Users create a new video project in the Synthesia web interface, write or paste a script, and select from available AI avatars and voice options. The platform synthesises the video by animating the avatar to deliver the script with appropriate lip sync and expression. Users can add slides, screen recordings, images, and background music. Finished videos are rendered in the cloud and can be shared via link or exported as MP4 files. Custom AI avatars can be created from an approved recorded video of a real person.
