Put Room’s Four-Digit Clipboard

Field notes

Put Room organizes cross-device transfer around a temporary room rather than a persistent account or clipboard history. A sender creates a room, shares its four-digit code or QR code, and adds text, source code, images, or files for connected devices to see. Its stated storage model allocates space to active rooms, returns unused capacity to a shared pool, and recovers it when rooms expire. The page does not specify expiration timing or file-size limits.
