Build interactive logic maps that read like a story.
LogiMapper turns columns, boxes and arrows into a sharable, browsable picture of how a theory of change, a benefit chain, or a strategy actually hangs together. This guide gets you from a blank page to a published map.
Owners use accounts; viewers can use an access code.

What is a logic map?
A logic map is a left-to-right chain of cause and effect. Each column is a stage (for example: inputs, activities, outputs, outcomes, impacts), each box is a thing happening at that stage, and each arrow says this leads to that. LogiMapper makes those chains interactive: hover an arrow to read its meaning, click a box to highlight only the chain it sits on, and share the whole thing as a single URL.
You don’t have to follow theory-of-change vocabulary. Teams use the same structure to show benefit cascades, forecast driver chains, customer journeys, and scheme-scoring frameworks. The examples page walks through five of those.
