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

Orato Flow - AI Translation for Events is real-time translation software for live events and conferences, offering instant captions and audio in over 70 languages. Attendees scan a QR code, select their language, and receive live captions or audio on their devices via earbuds or speakers. The platform supports bilingual or single-language displays, with HDMI connectivity for projecting captions onto venue screens in customizable layouts. A custom glossary allows real-time updates to terminology, and mobile hosting lets speakers manage translations from smartphones. Hosts can download transcripts and SRT files post-event. Remote attendees can access live captions, ensuring inclusivity for all participants.
