Vyo
A Cursor skill that reads a codebase and explains the app in plain English, on posters a non-engineer can read: how the app works, the project story, and an exploded view of its real parts. A built-in checker holds every poster to Swiss grid rules before it ships.
Code explains itself only to coders
Clients, PMs and founders live with an app they can't read. Handoff docs go stale, and walkthroughs disappear after the call.
A poster, not a document
The skill scans the repository and lays out what it finds on a real 12-column grid: journeys, screens, what runs under the hood, and an exploded view drawn from the code itself.
Rules a machine can check
Two styles, Swiss and a Farrow-inspired Block. A checker renders each poster in Chromium and fails it on an off-grid line, a fifth type size or low contrast. Exports are PNG, PDF and editable SVG.
A shared picture of the app
One sheet a non-engineer can read in a minute and talk about with confidence.
