## About Line 21
Line 21 provides AI-powered live captions and subtitles, ensuring seamless accessibility for live events, streaming platforms, and digital content. Our hybrid approach combines AI automation with human expertise, delivering high-accuracy captions that adapt to industry-specific terminology, accents, and niche references. By leveraging our AI Proofreader, we enhance real-time captions, reducing errors and making live experiences more inclusive and engaging. Our solution is designed for event organizers, broadcasters, and language service providers who need scalable, cost-effective, and high-quality captions. Traditional human captioning is expensive and non-scalable, while ASR solutions often lack accuracy. Line 21 bridges this gap by offering real-time AI-enhanced captions that integrate seamlessly into event tech and streaming workflows. With Line 21, businesses can improve accessibility, comply with regulations, and reach wider audiences. Our cloud-based platform reduces logistical costs and environmental impact, eliminating the need for in-person captioners. Whether for conferences, esports, or corporate events, we make live content truly inclusive, accurate, and future-proof.
