How AllGoodInsp compares

Giving AI agents design references is now a category. Screenshot libraries such as Mobbin and Lazyweb serve large collections of real app screens over MCP. Style extractors such as Refero Styles and various URL-to-tokens tools generate style files from existing sites. AllGoodInsp takes a third approach: a smaller, hand-reviewed collection of quality websites where every design decision is written out — and a synthesis step that turns several references into one working document.

What is different

Verbalized decisions, not just pixels. Each reference documents what every section does and why it works: typography, layout, color, motion, and information architecture, component by component. Screenshots leave the interpretation to the model; written rationale removes the guesswork. Motion and information architecture are the two layers most token formats — including Google's DESIGN.md spec — leave out entirely.

Synthesis, not lookup. The primary tool, extract_essence, merges 2–5 references into one ready-to-save DESIGN.md: normative tokens, CSS custom properties, a motion energy level, section structure, per-reference ownership of color/typography/layout/sections, and binding do's-and-don'ts. The agent gets a document to obey, not a pile of material to average.

Curation as the filter. Every reference is hand-reviewed and selected for intentional design decisions. Copying one famous brand's design file swaps one generic look for another; synthesizing from references chosen for your brief produces a direction that is actually yours.

When each approach fits

Use a screenshot library when you need mobile app UX flows and screen inventories. Use a style extractor when you already have a site and want its tokens formalized. Use AllGoodInsp when you need a new web design grounded in quality references — landing pages, marketing sites, brand and portfolio sites.

Why references at all

Model vendors themselves point in this direction. OpenAI's frontend design guide notes that underspecified prompts make models fall back to high-frequency patterns from training data, and recommends supplying reference screenshots and a defined design system. Practitioner guides report that extracting a reference into a structured design system before generating works better than handing the model a raw image. AllGoodInsp automates exactly that: curated references in, structured DESIGN.md out.
