What Synthesia does
Synthesia is an AI video platform that turns written scripts into polished presenter-led videos. In the video category it specializes in AI avatars, letting you produce a talking-head clip without a camera, studio or actor. You type or paste a script, pick an avatar and voice, and Synthesia generates a video with synchronized speech and captions. A large library of stock avatars, templates and AI voices covers common business use cases out of the box.
Who it is for
Synthesia is built for teams that produce a lot of instructional and communication video, such as L&D, HR, sales enablement and product marketing. Its strength is scale and localization: with support for 140+ languages plus translation and dubbing, one script can become videos for audiences worldwide. The editor adds slides, screen recording and brand kits so output stays on-brand. Pricing is subscription-based from around $18 per month, with a limited free plan to test the workflow before committing.
