# Restart CursorWorks the same way in both Claude Desktop and Cursor! Ask Claude to:
"List all PDFs in my Documents folder" "Show me PDF files in /Users/myname/Downloads"
"What form fields are in this PDF file?" "Read the form fields from application.pdf on my Desktop"
"Fill this W-9 PDF with my business information" "Fill the PDF at /path/to/form.pdf with John Doe as the name and save it to filled-form.pdf"
"Fill the template.pdf with data from employees.csv and save all PDFs to /Users/me/filled-forms/" "Use the 'employee_name' column for filenames"
"Save this as my 'work' profile: name John Doe, title Software Engineer, company Tech Corp" "Fill application.pdf using my work profile and save to filled-app.pdf"
"Extract all data from these PDFs to summary.csv"
"Validate if all required fields are filled in application.pdf"
"Read the content of this PDF: /path/to/document.pdf" "Convert this PDF to markdown format" "Extract all text from my estate planning PDF" "Summarize the main points in this contract PDF" "What does this PDF say about payment terms?" "Analyze this scanned invoice PDF" (automatically uses OCR)
Note: The read_pdf_content tool automatically handles both text-based and scanned PDFs
