Open Book – vẽ chung online

One notebook for everyone, for ever: write, draw, underline. What you put down stays.

A notebook of white pages that never ends, open to everyone at the same time. Ballpoint, pencil, marker and highlighter, with your pen's pressure if your screen feels it: write wherever you like, over other people's marks too, and watch theirs appear as they make them.

There is no eraser: a stroke once down stays for ever. There is whiteout, which covers in the paper's colour, but it is a stroke like any other. When a page is full you turn to the next, and you can leaf back through everything ever written.

No names, no photos, no typed text: only ink. We take off only what is illegal.
