The page https://www.chatpdf.com/?via=saasinfopro is likely related to a tool or service that allows users to interact with PDF documents using chat functionality. It probably enables users to ask questions about the content of the PDF, and the tool would provide answers based on the information within the document. This could be useful for quickly extracting information from large or complex PDFs without having to manually search through the entire document. However, without accessing the actual page, this is a general assumption based on the common functionality associated with such a domain name.
