PageNab

About

PageNab captures the full context of any web page and puts it in your clipboard — screenshot + text data — ready to paste into
  any AI coding assistant.

  One click captures:
  - Full page or area screenshot (image attaches directly when pasting)
  - Console errors and warnings with stack traces
  - Failed and slow network requests
  - Clean DOM snapshot
  - Cookies and storage data (sanitized)
  - User interactions (last clicks, scrolls)
  - Performance metrics (Core Web Vitals, load times)
  - Page metadata (URL, viewport, user agent)

  Three capture presets:
  - Light: errors + network summary (~500 tokens of text + screenshot image)
  - Full: everything including DOM snapshot, cookies, storage, performance
  - Custom: choose exactly what data to capture

  Features:
  - Screenshot pastes as an image (like a native screenshot)
  - Capture history with re-copy, details, and delete
  - Customizable keyboard shortcut for instant capture
  - Area selection mode to capture specific page regions
  - Sensitive data automatically sanitized (passwords, tokens, auth headers)

  Works with any AI tool: Claude Code, Cursor, Windsurf, GitHub Copilot, ChatGPT, or any LLM.

  All data stays local on your machine. No servers, no tracking, no analytics.
