Speak once.
Reach everyone.
One person speaks. Pentecost listens, understands, and translates into 50+ languages in under 1.5 seconds — then puts it on every phone and screen. So non-native speakers and attendees who are deaf or hard of hearing get the same message, at the same moment.

When people can't follow along, they quietly disconnect.
Maybe they speak another language at home. Maybe they're deaf or hard of hearing. Maybe they just walked in and don't know the room yet. Traditional interpreter booths are expensive and don't scale. Generic automated captioning mangles names, scripture, and jargon.
Pentecost was built so nobody gets left out.
It is tuned for the way people actually speak on a stage or platform, delivering the same moment to everyone: by ear or by eye, in the language they think in.
