Design-Context Extraction From Live Websites for AI Site Builders
Pablo, a Chrome extension that copies UI from any website into agent-ready context, surfaced a sharp observation in its HN thread: users prompt site builders from scratch when they could anchor on existing well-designed sites, and even with Pablo, models hallucinate copy and mangle heavy layouts. AI site generation quality is bottlenecked on design context, not model capability. Structured design extraction that agents can faithfully consume is the unsolved input side.
Problem Statement
A founder who wants their site to feel like a reference site today either prompts from scratch and gets generic output, or screenshots pages into the model and gets approximations with invented text. A Pablo user testing a sophisticated personal site reported varying degrees of success with the tool handling heavier parts poorly. Nothing today extracts spacing systems, type scales, and component structure into a format agents reproduce faithfully.
The Idea
A design-context engine for AI web builders that converts any live site into structured layout, token, and component specifications agents can rebuild from accurately.
Why Now
AI site builders multiplied through 2025-2026 and produce recognizably broken layouts, with one HN commenter asking why every LLM-created website has messed up margins and padding. Pablo's reception shows users want real sites as the source; the failure cases users reported, hallucinated copy and poor handling of complex pages, define the technical bar a serious product must clear.
Target User
Founders and designers using AI site builders, and the builder platforms themselves as API customers
