AriaSnap

About

AriaSnap extracts the full ARIA accessibility tree of any webpage and copies it to your clipboard as clean YAML — the exact format that LLMs, Playwright, and AI coding agents understand best.

LLMs work best with semantic structure, not raw HTML. AriaSnap gives you the same noise-free DOM representation that Playwright uses internally — buttons, headings, links, roles, and labels, without the visual clutter.

USE CASES
• Feed page content to ChatGPT, Claude, or any LLM for analysis or summarization
• Generate Playwright or Puppeteer test selectors from real pages
• Debug accessibility issues on any website
• Prototype AI agents that need to "see" a page
• Extract page structure without copy-pasting messy HTML

HOW IT WORKS
Click the toolbar icon, press "Copy to Clipboard" — done. You get a clean YAML tree with a line count and token estimate so you know it fits your LLM's context window.

Uses Playwright's battle-tested ARIA engine, embedded locally. Zero network requests. No data leaves your browser.
