Synthesia produces video of a person presenting, generated rather than filmed. Pick an avatar or create your own, paste a script, and get a finished presenter video — in over a hundred languages, with lip movement matched to the audio. For corporate training, onboarding, product walkthroughs, and internal communications, that removes the cost and scheduling friction of filming, and it makes updating a video as cheap as editing a document.

The second capability is localization. Translating an existing video while keeping the speaker's voice and mouth movement is expensive and slow to do conventionally; doing it in a few clicks changes the economics of multilingual content entirely. For companies that produce the same training in eight languages, the saving is substantial.

The honest limits are format and polish. This is a talking-head product: there is no cinematography, no narrative storytelling, and no way to build something that does not look like a presenter at a desk. Viewers increasingly recognize the format, which matters for external marketing more than internal use. Higher-tier features and longer videos consume credits quickly, and enterprise capabilities sit above the self-serve plans.

The free Basic plan includes a monthly credit allowance, roughly ten minutes of video, which is enough to judge whether the workflow suits you.

A practical consideration for anyone planning a library of videos: the cost model rewards planning ahead, since scripts consume credits and revisions are cheaper than reshoots but not free. Building a template — consistent framing, lower thirds, intro — makes a series feel intentional rather than assembled ad hoc. For internal audiences the format is now familiar enough that viewers judge the content rather than the delivery.

One thing to decide early is whether avatar video is the right format at all. For process explanations, compliance training, and product updates it clearly is. For anything where emotional register matters — a difficult leadership message, say — a real face is worth the filming, and an avatar can read as evasive.

Best for corporate training, onboarding, and multilingual communications. Not for creative or cinematic video production.
