Prizm: Video Call Translator

Live translation for video calls, phone calls, chats and voice notes. You speak your language, they hear yours.

Prizm brings translated calling and messaging together in one app. Start a video call, voice call or chat with someone who speaks another language. Prizm translates your conversation as it happens and speaks the translation naturally in the other person’s language.

No typing. No waiting. No passing the phone back and forth.

Whether you are calling family abroad, talking to a client, travelling, or meeting someone from another country, Prizm helps you communicate naturally.
