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

XRAI is an AI and augmented reality communication platform that converts live audio into real-time subtitles and visual text you can see on smart glasses or screens, helping users caption, translate, and understand conversations as they happen. The award-winning app performs high-accuracy speech transcription and supports multilingual translation across many languages, identifies speakers, and offers cloud-enhanced processing with options for offline use, while letting users stream captions to multiple devices simultaneously. Beyond basic subtitling, it includes AI-powered features such as conversation summarization and assistant tools that can answer queries and organize spoken content, and users can save, search, share, or manage transcript history. Designed to work seamlessly with the next generation of augmented reality smart glasses as well as phones, tablets, and desktops, XRAI Glass enriches everyday interaction by transforming speech into visuals.
