How It Works

1. User uploads a PDF file through the web interface.
2. The app extracts text from the PDF using PyPDF2.
3. The extracted text is sent to the Claude API with a structured prompt.
4. Claude returns a formatted summary with an overview, key points, action items, and a bottom line.
5. The summary is displayed in the app and can be downloaded as a .md file.
