Pentecost is a complete platform — capture, accuracy, translation, delivery, and operations — built for live, spoken-word gatherings.

Everyone Included

"Nobody in the room gets left out."

Live captions on every phone and screen for people who are deaf or hard of hearing; translation into 100+ languages so non-native speakers and newcomers follow along — read by eye or heard by ear.
