Another good option is Coral AI. The service lets you extract information from PDFs in more than 90 languages. It can summarize documents, answer questions, translate, generate citations and create study guides. Coral AI is geared for people who want to quickly analyze documents and are willing to pay for the convenience. That's a good option for many people.
If you want something more conversational, ChatPDF offers a different approach. You can upload PDFs and ask questions, and it'll provide detailed answers and summaries. ChatPDF can handle PDFs in any language, but it's geared for students, researchers and others who want to quickly understand documents. It can handle multi-file conversations and cite sources, too, so it's good for people who want to ask followup questions and keep track of a lot of documents.
