How BabelCast compares.

There are good tools for meetings and expensive rooms full of interpreters. BabelCast is built for the thing in between: live, one-to-many events.

Human interpreters / RSI
KUDO, Interprefy

Excellent quality, but expensive, booked in advance, and limited to a few languages. Built for enterprise budgets.

Meeting tools
Zoom, Teams, Google Meet

Great for calls, with real translation built in — Zoom now offers translated voice in five languages and event-livestream captions. Still meeting-first: participant-oriented and in-product, not built for venue displays or production workflows.

AI-native startups
Glossa, Palabra, DeepL Voice

Strong AI translation, but split focus: developer platforms on one side, single-vertical products on the other, with event pricing that can run high.

Where BabelCast sits: event-native, one-to-many, and openly priced.

What actually sets us apart.

Free listeners, flat pricing

Add ten listeners or ten thousand. You're billed by the source-hour, never per person.

Fast enough to feel live

Captions land under a second behind the speaker; natural translated voice follows a beat later. In the room, that reads as live.

Glossary & brand-term control

Your names and terms stay correct across every language. Configured with our team during early access.

Built for events, not meetings

Host console, venue display, and streaming sources: the whole event stack.

Go head-to-head.

Honest, detailed breakdowns against the tools you’re probably weighing.

Questions, answered.

AI live translation is the practical alternative when interpreter budgets or lead times don't fit. BabelCast translates a live speaker into dozens of languages at once, from $25 per source-hour, while on-site interpreters typically start around $500 per event and cover one or two languages. Listeners join in the browser from a QR code, with no app or account needed.

Zoom's Voice Translator is a meetings add-on that speaks exactly five languages: English, Chinese, French, Japanese, and Spanish. BabelCast is built for live one-to-many events: it runs up to 16 languages at once, listeners join free from a QR code in the browser, and captions feed venue screens and OBS or ProPresenter. Zoom fits interactive calls; BabelCast fits a speaker broadcasting to a large multilingual audience.

BabelCast starts at $25 per source-hour pay-as-you-go, with memberships from $99 per month that include 5 source-hours and lower per-hour rates. Listeners are free and never metered per person, and running more languages within your plan never multiplies the bill. One-time event passes are available too: a $199 Day Pass and a $799 Conference pass. Annual billing takes 20% off any membership.

Neither. BabelCast bills by the source-hour: the time your live audio is actually being translated. Listeners are free and never metered per person, and languages within your plan never multiply the bill; plans allow 4, 8, or 16 languages at once. Usage follows detected speech with a 50% live-session minimum, and very large audiences follow fair-use capacity limits.

See the difference yourself.
