Stage Captions

Stage Captions is a web application that turns live speech into closed captions instantly. You use it directly in your browser to capture audio from a presenter and display the resulting text on large venue screens, within live video streams, or on attendees' personal smartphones and tablets. The core function is accessibility, making events understandable for everyone, including those who are deaf or hard of hearing, without requiring any software installation for the audience.

The tool works by having a presenter or producer create a 'room' in their browser, select an audio source (like a microphone or system audio), and choose a language. Its standout feature is the low-latency captioning engine, which aims for minimal delay between the spoken word and the text appearing. You can add custom dictionaries to ensure technical terms and brand names are transcribed correctly. The captions are then distributed via a simple viewer link or QR code for attendees, or through a browser-based output that integrates with professional broadcasting software like OBS Studio.

This tool is a direct fit for event organizers, conference producers, educators, and broadcasters. A university lecturer could use it to provide captions for a large lecture hall, with students following along on their phones. A corporate events team could display captions on screens during a keynote and simultaneously stream them to a live YouTube broadcast. It simplifies the technical challenge of making live spoken content accessible in real-time.
