Our verdict on Prism by Busony
Prism by Busony provides browser-based simultaneous interpretation for multilingual meetings, webinars, and events. Speakers publish audio through a WebRTC session, while participants choose a language for translated speech and live captions. Host and co-host roles, floor control, chat, raise-hand queues, and screen sharing support organized sessions. It suits teams that need translated audio for specific gatherings rather than a standing subscription, especially when participants may join from mobile browsers without downloading an app.
Pricing is per session, with options for duration, language count, and event format. One-language meetings cost €9 for 30 minutes or €15 for 60 minutes, with up to 50 participants. Bilingual meetings cost €12 or €19 for those durations and allow up to 15 participants. Multilingual meetings support up to five languages and 25 participants, at €22 for 30 minutes or €39 for 60 minutes. The standard webinar costs €35 for 30 minutes, with up to five languages and 50 participants; the large webinar costs €55 and supports up to eight languages and 200 participants. The vendor also advertises a free 30-minute demo, not a free ongoing plan.
The feature set extends beyond translation: participants can select caption languages, while hosts manage speaking permissions and hand-raising. Busony says its language catalogue contains 70 languages, with up to 30 active simultaneously. That gives organizers options for multilingual events, but the published session plans impose different language and attendee limits, so buyers should match a plan to the format and audience. Prism is a fit for small meetings and webinars where session-based pricing and translated audio matter; organizations needing interpreter routing or a no-cost ongoing plan should look elsewhere.
