ChatPDF

ChatPDF is a simple way to talk to a document. You upload a PDF, such as a paper, manual or contract, and ask questions in plain language, getting answers with references to the pages where the information was found. It works with many languages, can summarize long files and handles multiple PDFs in a folder. No setup is needed, and you can start from the browser or an API. ChatPDF has a free tier with daily limits and a paid plan for bigger files and more questions. It is a quick choice for students and professionals who read a lot of PDFs.
