Upload PDFs or documents directly to the AI

Most paid AI tools now accept file uploads. Drop a PDF, Word document, or spreadsheet directly into ChatGPT, Claude, or Gemini and ask questions about its contents. This avoids manual copy-pasting and preserves document structure.

Why It Works

File upload lets the AI process the entire document in context, including tables, footnotes, and formatting that gets lost when copy-pasting plain text.

Tips

• Claude handles very long documents well due to its large context window
• Ask targeted questions after the summary: "What data supports the main conclusion?"
• For scanned PDFs, check that the AI can read the text — some scanned documents need OCR first
