About
Sync.so is a professional-grade AI lip-sync and visual dubbing platform developed by Synchronicity Labs. Designed for films, advertisements, podcasts, games, and animations, it delivers studio-quality lip-sync that preserves an actor's original performance across any language — making it an essential tool for localization and global content distribution. At the core of the platform is Sync-3, the company's most advanced lip-syncing model, engineered to handle demanding production scenarios: objects blocking the face, multiple faces in a single frame, multiple camera angles, low-light environments, fast camera movements, and rapid dialogue. The platform supports 4K ProRes output for broadcast and cinema-grade workflows. Sync.so offers multiple integration points: a browser-based web studio for direct use, a REST API for programmatic access at scale, an Adobe Premiere plugin for seamless editorial workflows, and a ComfyUI node for AI pipeline integration. A proprietary watermarking and video verification feature lets users confirm whether any video was modified using Sync's technology. The platform is suited for post-production studios, content localization teams, game developers, social media creators, and enterprise marketing teams. Available models include React-1, Lipsync-2-Pro, and Sync-3, catering to different quality and performance trade-offs. For projects requiring white-glove service, Sync.so also offers direct team collaboration.
