Free Online Clipboard

Copy & paste between your devices - no sign-up, no app.

Open a board under any name, put text or files on it, then open the same address on your other device. Whatever is on the board is there immediately. Boards clear themselves after a while, so nothing piles up.

Any name will do - keep the suggested one, or invent your own. Long and unusual is better, because anyone who knows the name can read the board.
