Leveraging artificial intelligence technology, ChatPDF allows users to ask questions and get insights directly from their PDF files, making it easier to prepare for exams, conduct research, or analyze financial reports. It's essentially like having a ChatGPT, but exclusively for PDFs.

How it Works:

ChatPDF utilizes a semantic index created over all paragraphs of the uploaded PDF. When a question is posed, it uses the ChatGPT API to generate the most relevant answer, based on the most pertinent paragraphs from the PDF.

FAQs:

• Table and Image Support: While ChatPDF can read text in tables, it may have issues correlating rows and columns correctly. It currently does not support images.
• Technology: The platform is currently using GPT 3.5 but is considering an upgrade to GPT-4 for better performance.
