An IDE that turns your codebase into a graph you can edit.

A box holds one session at a time, and that limit is enforced: if someone is already inside, the box will turn you away rather than let two people edit the same everything at once. The same applies to your own second tab, which is the most common way people hit it. One tab per box.

Work persists. Whatever you leave behind is still there when you come back — and the next visitor can read it. Demo work only: nothing private, nothing real.

The boxes sit behind single sign-on and are invite-only. Without an invite the link will refuse you, so ask for access first.
