A high-speed, keyboard-first Chrome Extension to capture and batch text for AI prompts.

Stop tab-switching. Start stacking. Context Stack is the ultimate research companion for the AI era. It allows you to rapidly capture text from multiple sources, organize your thoughts, and send comprehensive context to ChatGPT, Claude, or Gemini in a single click. 🚀 Why Context Stack? Most AI workflows are broken. You copy from one page, switch tabs, paste into ChatGPT, switch back, copy again... it's a context-switching nightmare. Context Stack solves this by letting you stay in your flow. ✨ Key Features ⚡️ Lightning Fast Capture Don't break your focus. Highlight any text on any page and press Cmd+E (Mac) or Ctrl+Shift+E (Windows). The text is instantly saved to your stack sidebar without you ever leaving the page. 📚 Batch Your Research Gather information from 5, 10, or 20 different sources.
