The Line
A phone call you type.
A live one-to-one line. Every keystroke appears on the other screen as it’s typed — no send button, no history.
Look someone up and their phone rings. When they answer, the line is live: you both type at once and watch each other’s words arrive letter by letter.
Nothing is stored. There is no inbox and no history, because there is nothing to put in one. The line closes after 60 seconds with nobody typing.
