Viewers, QR codes & languages

Viewers never sign in and never install anything. Everything below happens at captioncast.io/d/your-slug , a public link.

How viewers join

Open the display link on any phone, tablet, or laptop browser. If the URL doesn't specify a language, you land on a picker screen listing every caption language enabled for that meeting.

Choosing a language

Tap a language on the picker (or go straight to /d/your-slug/es for Spanish, for example) to see a single-language caption feed that fills in as the speaker talks.

Side-by-side (split view)

Request two languages at once — /d/your-slug/en,es — and both appear side by side on one screen, aligned by utterance. This is meant for a projector or TV in a mixed-language room. The picker screen offers a direct "Side-by-side" link whenever a meeting has two or more caption languages enabled. If a URL asks for more than two, only the first two are shown.

QR codes

Every meeting's control panel shows a QR code that opens its display link directly. There's also a dedicated full-screen QR page at /d/your-slug/qr — meant for a screen the whole room can scan — which lists each enabled language next to its own direct link.

Making text bigger

Every viewer has their own A− / A+ controls in the bottom-right corner of the display, so someone reading on a phone can enlarge captions without changing anyone else's screen. A reset link appears once you've zoomed, in case you want the operator's default size back.

Language limits

How many caption languages a meeting can enable at once is set by your organization's plan — two by default (English and Spanish). That's independent of your credit balance; see Billing & credit packs for how minutes work. If you need more languages enabled, contact support.
