# Designesy — / Canonical page: https://www.designesy.org/ --- Contract **v0.4.3** is live · **44** checks, rescored weekly ## AI makes execution free. We make execution provable ** . Designesy publishes design judgment as a versioned contract, then verifies any live page against it. One grade, with evidence you can cite. designesy.org is held to the full contract; every other site gets the Universal reading. Legitimacy Audit Engine Enter any public website URL above (no https:// needed). We fetch its CSS, extract design tokens, and evaluate 44 verification checks against the Designesy contract v0.4.3.

Each of the 44 checks inspects a part of the page. A finding pins to the element it flags, named by the check that caught it. 1. 01 It reads the page you ship The engine loads the live URL the way a visitor does and walks what actually rendered: markup, tokens, type, spacing, and motion. 2. 02 It measures instead of guessing Contrast is computed, never eyeballed. Line length, type scale, and target size are read off the page, each against a threshold the contract publishes. 3. 03 Each finding pins to its element A check that fails names itself and marks what it caught. Here v03 finds no focus-visible ring on the button, and v06 measures the muted text at 3.8 to 1. 4. 04 One grade, with the evidence attached Findings roll up into one score. Neither finding here carries a score ceiling, so the page grades A, and every result links back to the rule that produced it. Tokens, components, and checks in one place, so the page you ship is the page you designed. p · 17 / 27 ** 0 9 18 27 35 44 53 62 ch 1 **v06** muted text 3.8 : 1 *warn* Demo on a generic page. The checks and their thresholds are the engine’s own. ## Coherence is how a site earns trust now. When AI can generate any interface, trust goes to the sites that hold together: consistent type, coherent motion, a steady rhythm. The contract makes that coherence checkable. 44 checks run against the live page, and each one passes or fails in the open. 01 ### Taste codified The contract encodes design judgment as tokens, motion, sound, takt, and cadence, so taste survives any tool, any team, and any AI that generates your UI. 02 ### Verification as proof 44 automated checks prove the contract is met. With 42% of committed React now AI-generated, the score measures what shipped: the rendered page a visitor meets. 1 03 ### Anti-generic by design Twelve anti-generic tells detect when a surface has defaulted to the AI mean. No generator has this. The contract is the structural defense against AI sameness. 04 ### Multi-surface hardening Every new surface that ingests the contract stress-tests it. Each failure closes a gap the AI tools left open. The contract gets stronger with every generation. 1 The 42% figure: Belitsoft, State of React Development 2026. ## Nine principles. One contract. Every check traces back to a principle. Check them off as you read; the full wording lives in the doctrine. 1. Type 95 2. Motion 90 3. Color 95 4. A11y 88 5. Space 92 6. Hierarchy 95 7. Interact 90 8. Provenance 100 ## Four ways to put the contract to work. ### Design system contract The rules behind this site, portable and versioned. Tokens, motion, components, and the Poise, Takt, Cadence, and Acoustics rules. A human overview, plus a machine export agents can cite directly. ### Design Review Turn taste into inspection. Point your agent at any design. Eight dimensions, a copyable agent prompt, output format, and verification checklist. Human and machine read the same rules. ### Try the Studio The contract, conversational. Ask about type, motion, or spacing, or score any site. A conversational instance of the Designesy Director. It answers from the designesy.org contract: tokens, principles, and open tensions. ### Continuity Design judgment that stays current. Score, contract, verify, and keep the receipt. Open core stays free. Continuity adds history and drift for work that continues. ## Every surface is public. ## What is real on this site.
