What is Synthesia?
Synthesia generates videos of an AI avatar speaking a script you provide, in dozens of languages, without needing a camera, studio or human presenter. It's widely used for training videos, product explainers and internal communications where a talking-head video is useful but production resources are limited. Plans are priced per seat with a monthly video-minute allowance; there's a limited free trial rather than an ongoing free tier. The main appeal for organizations is repeatability at low marginal cost: once a script is written, producing the video doesn't require booking a presenter, a studio or a camera crew, which matters most for content that needs frequent updates (compliance training that changes yearly, product explainers that need a new language version, internal announcements). The tradeoff is presentation style — an AI avatar reads noticeably differently from a human presenter, which fits some brand contexts (internal training, neutral explainers) better than others (consumer-facing marketing that leans on personality or spontaneity).
