PixelLens

Turn any web page into clean Markdown for AI, and extract its full design system: colors, type, spacing, tokens. Local, no API key.

Feed your AI real pages, not screenshots. PixelLens turns any web page (or an entire site) into clean, structured Markdown your AI assistant can actually use, and extracts the page's full design system while it's at it. Everything runs locally in your browser: no server, no account, no API key, and your data never leaves your machine. ■ PAGE → MARKDOWN (free) Convert the current page into clean GFM Markdown with YAML frontmatter (title, URL, capture date, word count): copy it or download the .md file. Headings, links, images, tables and code blocks are preserved. ■ CRAWL A WHOLE SITE (free: 3 pages · Pro: up to 100) One click crawls every same-site page (sitemap-first, falling back to link crawling) and concatenates them into a single Markdown document with a table of contents, ready to paste into an AI's context window. Two render modes: Fast (server HTML) or Full (each page rendered in a real background tab, so JavaScript-heavy SPAs convert too). Download as one .md or a multi-file ZIP. Respects robots.txt by default. ■ COPY FOR LLM (Pro) One button copies a single self-describing bundle: the page as Markdown + the extracted design system + page metadata. Paste it into Claude, ChatGPT or any assistant and it understands the page end to end. ■ DESIGN SYSTEM EXTRACTOR (free) Scan any page and get its palette (clustered and auto-classified), type scale, spacing scale, shadows and border radii. Check WCAG contrast ratios. Inspect any element: box model, computed CSS, one-click copy of any value. Grid overlay and distance measurement included. ■ EXPORT YOUR TOKENS (Pro) Ship the extracted design system as CSS variables, a Tailwind config, JSON tokens (Style Dictionary compatible) or a PNG palette. Rename and prune tokens before exporting. Keep your full scan history. ■ PRIVACY, FOR REAL No analytics, no telemetry, no account, no remote server. The only service PixelLens ever talks to is ExtensionPay (extensionpay.com), and only when you buy, restore or verify the optional Pro upgrade. Site crawling happens from your own browser, on the site you chose, with your own session. Free forever for inspecting, scanning, contrast checking and single-page Markdown. Pro is a one-time 19 € in-app purchase (Stripe via ExtensionPay): lifetime, no subscription, no license key to manage.
