What it does

sync. (Synchronicity Labs) makes lipsync models that edit an existing video so the speaker's mouth matches a new audio track, the last step of a dubbing or line-replacement edit. Its open-source MCP server generates tools from the API spec at startup and works in Claude Code, Claude Desktop, Cursor and Windsurf.
