# multicardz

> Spatial tag manipulation system for organizing information.
> Drag tags to filter cards. Group by rows and columns to find patterns.

multicardz lets you drop the same card into many tag intersections
simultaneously. The same card can be "urgent + backend + bug" in one
view and "this week + Alice's queue" in another, without duplication.

## What it is

- A web app for filtering, grouping, and visualizing cards using
  drag-and-drop tag spatial manipulation.
- Built on set theory: every filter is a frozenset operation
  (intersection, union, difference) over the workspace.
- Patent-pending spatial paradigm: tags placed in different drop
  zones produce different operations (filter, group, exclude).
