Synthesia

Synthesia solves one expensive problem completely: video that has to be updated often. A compliance module recorded with a real presenter costs a studio day to change a single sentence. In Synthesia you edit the script and re-render. For L&D and internal communications teams that alone justifies the subscription.

The 140-language support compounds it. Producing an onboarding course in twelve languages is a scheduling and budget problem that mostly does not happen; here it is a translation step. Reviewers in multinational organisations consistently name this as the feature that moved them from evaluating to buying, and the avatars are licensed from paid actors, which gives the commercial-rights position most enterprises need.

The limit is audience tolerance. Avatars have improved but remain identifiably synthetic — a slight stiffness around gesture and eye-line that viewers notice even when they cannot name it. Our reviewers report that internal audiences accept this readily and external marketing audiences do not, which is a useful rule of thumb. Per-minute pricing also adds up quickly at volume.

Our guidance: excellent for training, onboarding, product updates and internal comms, particularly multilingual. Not yet the right tool for brand-facing marketing video where a real presenter still reads better.
