Sync Labs
Sync Labs provides an AI lip-sync API that generates mouth movements matched to video and audio. Its listed models include lipsync-1.9, lipsync-2, lipsync-2-pro, react-1, and sync-3. The introduction lists 512×512 face resolution for lipsync-2 and lipsync-2-pro, and native 4K for sync-3. The models use audio waveforms rather than text and support 29 spoken languages, including tonal languages such as Mandarin and Thai. Use cases include dubbing, localization, personalized video messaging, e-learning, marketing, entertainment, media, and gaming. Developers can use a REST API and official Python and TypeScript SDKs; documented integrations include Adobe Premiere, DaVinci Resolve, ChatGPT, an MCP server, ComfyUI, and ElevenLabs. Inputs include MP4 video and WAV or MP3 audio, provided by public URL, API upload, or media-library asset ID. The free plan provides 3 generations per month, each up to 20 seconds, and no credit card is required. Hobbyist costs $5 a month plus $0.05/sec; paid plans also list usage charges. The service is available via API and web.
