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

Generate open or closed captions for videos automatically, in a matter of minutes. Subly will do the heavy lifting, so you can focus on making subtitle edits and styling your video, ready to share faster with your audience. You wouldn’t share a video without image or sound. So why leave out the text? Subtitles can help to get the attention of those with sound off, deaf or hard of hearing. Making sure they can understand your content, whilst your engagement soars too. You can generate subtitles or captions automatically, by typing the text in the subtitle editor, or by uploading your own SRT file. Quickly make amends to the timings inside the subtitle editor or move your subtitles in the timeline. You may also preview your video with the subtitles to confirm they are accurate and in sync.
