Sync

Sync (sync.so) is an AI lip-sync platform and API that generates video where a speaker's lip movements are synchronized to a given audio track, used for dubbing, localization, and AI avatar or talking-head video generation. Developers integrate it via an API and SDKs, with features such as active speaker detection, voice cloning for a limited number of voices per plan, and a custom text-to-speech API key on higher tiers. Pricing combines a monthly base subscription with usage-based charges per second of generated video, and plans differ in maximum video length, concurrent job capacity, number of clonable voices, and included team seats. It targets developers and video/localization teams building dubbing or synthetic-video features into their own products, from individual builders on the entry Hobbyist plan up to teams needing batch processing and dedicated support on the Scale and Enterprise plans.
