About
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.

About
We ensure your content reaches as many people as possible. Whether you’re creating a program, hosting a conference, or planning an event, adding captions and/or audio description provides accessibility and engagement for all. At VITAC, we’re here to help ensure that the process goes smoothly. We’re the largest and most trusted captioning company in the United States, and our investment in our people, process, and technology are unmatched in the industry. Captioning is the art of transcribing the audio portion of a video, program, or event into text and displaying that text on a screen. These captions can appear on a television, movie, computer, or mobile device. Captions largely are used by members of the deaf and hard-of-hearing community, and captioning a program, conference, or event goes a long way towards making it inclusive and accessible to all.
