If you want to extract key information from PDFs without having to read the whole document, ChatPDF is a great option. This AI-based interface lets you upload PDFs and ask questions and get answers and summaries. It's good for people who need to process research papers, academic documents, contracts, financial reports and training manuals. ChatPDF works in multiple languages and can handle a large number of PDFs, so it's a good option for anyone who needs to get answers out of documents.
Another option is PDF GPT, which has the same abilities as ChatPDF but also can translate, generate citations, search for information and generate study questions. It works in more than 90 languages and can be used with books and legal documents. PDF GPT offers a free version and a Pro version with features like unlimited file uploads and chats that can save you hours of work.
If you prefer a more conversational interface, AskYourPDF uses ChatGPT. It's good for getting information out of long PDFs, and it offers a Chrome extension and a history of your conversations. It also offers a few pricing tiers, including a free version with some limitations.
