Synthesia is an AI video generator that creates videos with digital presenters. Instead of filming, you write or paste a script, choose one of the stock avatars or create one of yourself, pick a voice and language, and Synthesia renders a video complete with slides, media and captions.
It is widely used for corporate training, onboarding, product explainers and internal updates, and supports translation into many languages so one video can serve global teams.

Our experience using Synthesia
For training content, Synthesia is a huge time saver: a slide deck becomes a narrated presenter video in under an hour, and updating it means editing text rather than reshooting. Avatars are convincing at normal viewing sizes.
For social media or more expressive marketing videos, HeyGen offers more creative avatar options. For voice only, use ElevenLabs.
Who should use Synthesia?
Synthesia is best for L&D teams, HR, internal communications and product marketing teams that produce lots of explainer and training videos.
Synthesia vs alternatives
HeyGen is the main alternative with strong marketing and translation features. Runway and Pika are for generative cinematic video. For voiceovers only, see ElevenLabs and Murf.
