Synthesys

Synthesys, built by London-based Nouveau Media Ltd (established 2020) and used by more than 50,000 creators and businesses, transforms text, images, and URLs into professional videos without traditional production needs, generating ads, reels, training videos, and product demos using AI avatars and voices. It offers more than 1,000 AI avatars in 4K resolution with customizable clothing, more than 400 voices across 140-plus languages with lip-sync capability, and multi-model AI orchestration integrating Sora 2, Google VEO 3.1, Kling 3, and other frontier models. Synthesys includes voice cloning and face-swap technology for custom digital twins, built-in royalty-free music and sound effects, and full commercial rights on all plans. The company estimates AI video generation costs about $0.50 per video versus $5,000-$20,000 for traditional production.
