Synthesys
Multi-model AI video agent: avatars, UGC ads, voiceovers, and dubbing in 140+ languages.
About
Synthesys started in London in 2020 with AI voice generation and has grown into a multi-model AI video platform. It offers 1,000+ AI avatars, 400+ voices, text-to-speech and voice cloning in 140+ languages, talking-avatar videos, AI UGC ads, product videos, and multilingual dubbing with lip-sync. In 2024 it folded frontier video models such as Sora 2, Veo 3.1, Kling 3, and Wan 2.5 into its orchestration layer (vendor-reported), positioning itself as a one-subscription video agent.
The company reports over 1,000,000 videos generated for 17,000+ users, with enterprise customers including Coca-Cola and Yahoo (vendor-reported). A free trial is available; paid plans unlock commercial volumes and the full format range. Limitation: user and revenue figures come from the vendor, output quality varies across formats, and the richest features sit on higher-priced tiers.
