Relay reimagines voice communication from the ground up. When you make a call on Relay, your voice never travels the network as audio. Speech is transcribed on your device, encrypted, and transmitted as text. On the other end, your words are reconstructed in your voice but privately, in real time. Your conversations stay yours. How it works? Speech is transcribed locally on your device. Text is encrypted end-to-end using the McNeal Protocol. Your cloned voice plays on the receiver's device. No raw audio ever leaves your phone. Built for people who mean it Whether you're protecting sensitive business conversations or simply believe your voice calls shouldn't be anyone else's business, Relay was built for you. What makes Relay different? Most encrypted apps protect your messages in transit. Relay goes further because the audio itself is never transmitted. There's nothing to intercept. End-to-end encrypted messaging. Voice calls without audio transmission. On-device speech processing. No ads. No data selling. Ever. Your calls. Your voice. Your terms.
