Exploration · pre-decision
Read an argument by walking it, one step at a time.
Long essays go top-to-bottom or sprawl into a mind map you can’t read on a phone. These two mocks turn the same essay — Paul Graham’s “How to Earn a Billion Dollars” — into something you move through deliberately. Same words, same forks, two different shapes.
Linear · reveal-on-tap
Card Walk
One card per screen. Commit a guess, tap to reveal, advance. You only ever see where you are — never the whole map.
Spatial · click-through
Decision Tree
The argument as a map you navigate node by node. You always see the shape, your path so far, and where the forks split.
What to feel for
Do these collapse into the same thing in two skins, or does the tree shape earn its keep? Try the walk first, then the tree on the identical content. Watch what each one makes easy — and what it costs you, especially on a phone.
