Pick ChatPDF if…
ChatPDF suits students, researchers, and professionals who need to ask questions about or summarize document collections. Its citations, file-sharing controls, and API may also suit people building document-based workflows.
Pick PDF-ChatGPT if…
It suits users who can self-host an application and want cited answers across a library of PDFs. It is a poor fit for scanned documents unless they add OCR, or for public deployment without adding access controls.
