AI Context Collectorとは
Extract structured page context — colors, components, copy, images, code & tables — as clean JSON for AI chats and site builders. Turn any webpage into clean, structured JSON your AI can actually use. AI Context Collector extracts the meaningful parts of a page — design tokens, content, components, and code — and skips the noise. No minified bundles, no giant HTML dumps, no wasted tokens.
