MAKE ROOM FOR A CONVERSATION

Start your bridge.

Create a room, then invite one person. You each choose the language you speak.

Your key goes to this app’s server over HTTPS. It is encrypted for this room and never sent to your partner. Only use a host you trust.

No microphone access until you accept a call.
ChatGPT/Gemini subscriptions are not API keys.
Leaving disconnects your key. Test rooms expire after 2 hours.

A space for just two.

Chat with shared context, then try a translated call using generated AI voices.
