How It Works

A workflow designed for speed and simplicity.

1. Capture Anything, Instantly.

Press a hotkey and your screen dims, ready for selection. The "live" capture feels just like your operating system's native snipping tool. Drag a box over anything—a code snippet, a foreign language comment, a non-selectable error message—and the sidebar instantly appears with your capture.

  • Feels native and responsive, no lag.
  • Select text even from images or videos.
  • Uses blazing-fast native Windows OCR.

Click "Extract Text" and watch the image turn into selectable text in seconds. From there, the AI is at your command. Need to understand a piece of code? Click "Explain". Replying to a message? Click "Reply". The AI understands the context and gives you exactly what you need.

  • One-click text extraction from any image.
  • Multiple AI actions: Explain, Translate, Reply, Rephrase, and Answer.
  • Seamlessly copy the AI's response or the extracted text.
