Keynote → every attendee’s language

A global audience in one room.

International conferences draw attendees from everywhere, but interpreter booths are expensive and limited to a couple of languages. Multi-track events make it worse. BabelCast turns any session into a multilingual broadcast: attendees pick their language on their own phones, in the main hall or a breakout.

How BabelCast fits.

01

The speaker presents

Start a session per stage or track from a laptop.

02

We translate live

Captions and voice in every attendee language, simultaneously.

03

Everyone tunes in

Attendees join by code and switch languages between sessions.

What matters most here.

Free listeners

A packed hall or a global livestream: the price never changes.

OBS source

Feed live captions into your stream as a browser source.

Per-track sessions

Run parallel sessions, each with its own languages.

Recommended plan
Scale

Questions, answered.

A one-time Conference pass is $799, or a Day Pass is $199 for a single-day event. BabelCast bills by the source-hour and listeners are free, so a packed hall or a global livestream costs the same. For a busy events calendar, the Scale plan includes 130 source-hours a month, and annual billing works out to about $14 per source-hour.

Attendees scan a QR code or open a short link in their browser, pick a language, and follow captions and translated voice on their own phones. There is no app to install, no account to create, and no rental receivers to distribute or collect. Captions appear under a second behind the speaker, and attendees can switch languages between sessions.

Yes. BabelCast's live captions drop into OBS as a browser source using the session's display URL, with one language per source via a ?lang= parameter. Each stage or track runs its own session with its own languages, so parallel programs stay independent. A transparent overlay-style source is on the roadmap.
