Cartu — Structural readings, drawn
Trust and control sit downstream of comprehension.
The Frame
We are drowning in substance but starved for shape. Substance hides structure. Cartu extracts the architecture from dense public artifacts — skill libraries, essays, constitutions — and draws their maps. See the shape of the system before reading the text.
Cartu — from the Latin charta, a chart. The act of translating dense text into a drawn shape.

The Collection
Seven maps live today. More on the drafting board.
OpenAI published the GPT-5.6 System Card. See the ceiling, the bars, and the self-audit baseline in minutes before reading the full document.
The shape is capability bars held under a Critical ceiling, standing on a self-audit baseline. Each bar is a capability tracked against the ceiling; the copper anchor marks the self-audit that carries the whole frame.
Dario Amodei published a 5,800-word essay on AI policy. See the two-speed gap in minutes before reading the full essay.
The shape is a two-speed gap. AI capability curves upward while policy moves below it. Five policy areas bridge the distance, and the oxblood anchor marks the window of opportunity.
Pope Leo XIV published a 35,000-word encyclical on AI and human dignity. See the arc in minutes before reading the full encyclical.
The shape is a keystone arch between two towers. Six principles fitted as voussoir stones, with Dignity as the keystone. Two towers frame the arch: Babel (domination) and Nehemiah (rebuilding). Every applied position traces back through the arch to its foundational stone.
Anthropic shipped 213 skills for finance. See the quadrant in minutes before reading the full source.
The shape is a quadrant around a foundation. Eighteen archetypes organized into four families: Navigators, Gatherers, Analyzers, Makers. The Foundation sits at the center, distributing shared context to all four.
Anthropic shipped 151 skills for lawyers. See the wheel in minutes before reading the full source.
The shape is a 12-spoke ring. Twelve archetypes radiating from a central hub. That hub is the Foundation — the shared reference library every archetype plugs into. The shape tells you the library is a wheel.
Anthropic published Claude's Constitution. See the constitutional structure in minutes before reading the full document.
The shape is four pillars on a single baseline. Four core values rendered as columns. The baseline is Claude's Nature — the constraint that holds the pillars together.
Dario Amodei published a 20,000-word essay on AI risks. See the apex anchor in minutes before reading the full essay.
The shape is a pentagon web with an apex anchor. Five interconnected risks drawn as a fully integrated network. The origin point is Autonomy — the primary risk from which the other four cascade.
