What sync.labs does
sync.labs (legal entity Synchronicity Labs Inc.) is a San Francisco-based generative AI company founded in 2023 that builds audiovisual models for video lip synchronization and visual dubbing. Its core technology — proprietary models including sync-3, lipsync-2-pro, and react-1 — regenerates facial expressions to match new dialogue or translated audio while preserving the original actor's performance, emotion, and identity across 95+ languages without per-speaker training or fine-tuning. The platform handles challenging production scenarios (sharp angles, low light, multiple speakers, 4K 60fps, objects blocking the face) and supports professional codecs up to 4K 16-bit HDR with ProRes 4444XQ and uncompressed EXR output.
The company distributes through multiple surfaces: a browser-based Studio app (Lite and Pro modes) with a freemium tier of three videos per month at full HD, a REST API with Python and TypeScript SDKs, native plugins for Adobe Premiere Pro and ComfyUI, an MCP server for AI-assistant clients (Claude, ChatGPT, Cursor, Windsurf), and a managed enterprise service called Sync Productions. Voice capability is delivered through an ElevenLabs integration, and content authenticity is supported by proprietary watermarking/verification technology.
Commercially, sync.labs serves four customer segments: film and TV production studios needing studio-grade visual dubbing and ADR replacement; content creators and YouTubers localizing videos into multiple languages (named customers include MrBeast, Mark Rober, and Nas Daily); developers and platform integrators consuming the API (Kapwing embeds Sync into its AI Personas product); and enterprise clients on Sync Productions managed contracts. The company is privately held and venture-backed, with a $5.5M seed round led by Google Ventures in August 2024 on top of earlier Y Combinator, AI Grant, and Founders Inc. funding.

Functional benefit
Products and services
- sync.so Studio Browser-based Studio application that lets individual creators and prosumers upload videos, generate translations or dubbing with lip sync, and export the resulting localized video, without needing post-production tooling.
- sync.so API REST API that allows developer and product teams to programmatically access sync.labs lip sync and visual dubbing features to embed inside their own video, social, e-learning, or communication applications.
- sync.so Enterprise Enterprise-grade offering for film, streaming, and media studios that combines access to sync.labs models with bespoke production services (Sync Productions) for large-scale multilingual dubbing and localization projects.
- Adobe Premiere Pro Plugin Plugin that integrates sync.labs lip sync and dubbing capabilities directly into Adobe Premiere Pro, enabling professional editors to localize and dub footage inside their existing editing environment.
- Voice Cloning Voice cloning capability that produces a synthetic voice matching an original speaker, used to drive translated or dubbed audio that is then aligned to video via sync.labs lip sync models.
- Visual Dubbing End-to-end visual dubbing service that takes source video and produces a new version with translated speech, cloned or synthetic voice, and re-synced lip movements, used to localize video into other languages.
- Sync Productions Bespoke service for studios and large media clients in which sync.labs produces finished dubbed and lip-synced video content using its AI stack and production team, rather than the client operating the tools themselves.

sync.labs competitors and assessment
Company assessmentDirect peers
- HeyGen: AI video generation platform with avatar creation, voice cloning, and lip-sync-driven multilingual video. Competes directly with sync.labs for creator and enterprise video localization use cases, and has raised at substantially higher valuations.
- D-ID: Digital human / talking avatar platform that animates still photos and videos with lip-synced speech. Comparable to sync.labs' image-to-video and lip-sync capabilities for creator and enterprise avatar use cases.
- Captions: AI-powered video creation and editing app used by creators and short-form video producers. Offers AI dubbing, voice cloning, and lip-sync features, directly competing for the same creator/YouTuber segment.
- Hedra: Audio-to-video character animation platform with continuous performance animation including facial and lip movement. Targets the same creator and developer markets with audio-driven video generation.
- Synthesia: AI avatar video generation platform serving enterprise customers with synthesized talking-head videos in many languages. Overlaps with sync.labs on multilingual enterprise video, though Synthesia focuses on avatar-led rather than dubbing existing footage.
Broad incumbents
- Runway: Broad generative AI video platform with editing, generation, and increasingly lip-sync-related features. Well-capitalized incumbent competing across creator and professional workflows that overlap with sync.labs.
- Adobe: Creator of Premiere Pro — sync.labs' primary professional distribution channel via plugin — and Firefly Video. As Adobe ships native AI features, it represents both partner and existential competitive threat.
- ElevenLabs: Voice AI leader that powers sync.labs' voice cloning today via integration. ElevenLabs is expanding into video and dubbing capabilities, making it both a critical technology partner and a growing competitor.
Emerging players
- Akool: AI video generation platform offering face/avatar animation and lip-sync features for marketing and enterprise localization. Competes in similar use cases but with a broader generative video product surface.
Others
- Sieve: Video dubbing API platform that integrates sync.labs technology as a backend for its own dubbing pipeline. Strategic partner rather than direct competitor — illustrates the developer/API ecosystem play sync.labs is building.
