Quick Answer
Yes, most major AI models now support PDF uploads and analysis directly.
Detailed Answer
ChatGPT, Claude, and Gemini all support direct PDF uploads. Claude handles the longest documents with its 200K context window, making it ideal for legal contracts and research papers. ChatGPT's Code Interpreter can extract data from PDF tables. Gemini's 2M context can handle extremely large documents. For best results, use clean, text-based PDFs rather than scanned images.
