A diagram tool with one shape

Explain anything
to anyone.

One shape. As many layers as you need. Draw a layer for each audience, and keep the board's summary and the engineers' detail in one diagram.

One real example

One diagram. Every audience.

How people join, move through and leave a company, in one diagram. Each layer was drawn by hand for a different reader, and each is complete on its own.

4

Board

Someone joins, changes role, leaves, and access is reviewed.

19

HR and managers

Each hexagon traces back to one of the board's four.

55

Identity engineers

The red ones are the steps most often missed.

How it works

One shape. Multiple layers.

There is nothing to learn before you start, and very little to get wrong.

  • One shape

    Hexagons only. No lines, no arrows. Things that are related touch, and a hexagon has six sides, so you have to decide what matters.

  • Layer 1
    Layer 2
    Layer 3

    Layers

    When a layer gets crowded, the detail moves down a layer. Each layer is a complete diagram for one audience.

  • One start, read to the right

    Every diagram begins at one hexagon. The next step goes in the slot on its right, so anyone can follow it without a key.

With an AI assistant

Ask your own assistant to draw it.

Connect your own AI assistant to a free account and ask it to draw or change a diagram. It builds the layers and tells you what the colours mean. You move things until it is right.
