VoidCraft is a 3D space you and your agents share.
A folder makes you decide where something goes before you can keep it. VoidCraft is a 3D space instead: put anything down, anywhere, and find it again by where you left it, by an edge you drew to it, or by search. Any AI assistant can join you there (it connects over MCP): it reads the same space you walk through and proposes changes you approve, so your memory stays yours and works with whichever assistant you use.
