About
Sync. (also known as Sync Labs) is a San Francisco-based generative video AI company that develops industry-leading lip-syncing technology — enabling creators, media companies, and enterprises to modify video content so that a speaker's lip movements perfectly match translated audio or updated scripts in near real-time HD quality, powering video localization, dubbing, and post-production workflows that would traditionally require re-shooting or expensive manual animation. Backed by GV (Google Ventures), Nat Friedman, and Daniel Gross with $5.5 million in seed funding, Sync. graduated from Y Combinator's Winter 2024 batch with both an open-source model (Wav2Lip, 8,700+ GitHub stars) and a proprietary Lipsync-2 zero-shot model that requires no training data.

About
Grok is the AI assistant developed by xAI, Elon Musk's AI company founded in 2023, and distributed primarily through X (formerly Twitter). Grok launched in November 2023 as an X Premium perk, with the notable differentiator of real-time access to X posts and a less restricted, more direct conversational style. Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
