Synthesia Review (2026)
Create presenter-led videos with AI avatars in over 100 languages — no camera needed. Best for: Corporate training, onboarding and multilingual explainer videos.
What is Synthesia?
Synthesia lets you create videos featuring realistic AI presenters simply by typing a script. It is one of the most widely adopted AI video platforms in businesses, used for training, internal communication and customer education.
You choose a stock avatar or create a custom one of yourself, pick a voice and language, and Synthesia produces a professional-looking video. Updating the video later is as easy as editing text, which is a big advantage over reshooting.
