Synthesia

Synthesia turns text into professional-looking videos fronted by AI avatars, and it's become a default in corporate training and internal comms for a reason: it removes the entire production pipeline. No studio, no presenter, no re-shoots — type a script, pick an avatar, and render. When a process changes, you edit the text and regenerate rather than booking a film day.

With a large library of stock avatars, custom avatar creation, and speech in 140+ languages, Synthesia's strength is scale and localization. A single training video can be produced once and spun out into a dozen languages, which is transformative for global teams. The avatars are clearly synthetic on close inspection, but for talking-head explainers and L&D content that's rarely a dealbreaker.

The scene-based editor is approachable — slides, screen recordings, text overlays, and avatar placement all sit in a familiar layout. What it isn't is a creative video tool: there's no real motion graphics or cinematic control, and the format suits structured, informational content far more than marketing storytelling.

For training, onboarding, product how-tos, and multilingual internal video, Synthesia is one of the highest-leverage tools available — the time and cost savings are real. For brand or narrative video where production value and emotion matter, you'll still want a traditional workflow.
