How to use WebRTC Chat

Device A: "Start a chat". It shows an offer QR and turns its camera on.
Device B: "Join a chat". Its camera turns on; point it at A's QR. B then shows an answer QR.
Point A's camera at B's answer QR. The chat opens by itself once the data channel is open.
No camera? Each step also accepts pasted text and continues as soon as it is valid.

Privacy

Messages travel over a WebRTC data channel, which is encrypted with DTLS between the two browsers. No messages are stored on servers. The offer and answer contain your network candidates (IP addresses); share them only with the person you are chatting with. A TURN relay is not configured yet, so networks that block direct connections (for example some mobile carriers) will not connect.
