ChatPDF
Description
An AI service for working with PDFs and other files: you upload a document, ask questions about it and get a summary. Answers carry built-in citations that point to places in the document, and several PDFs can be organized in folders and discussed in one chat. It also accepts videos and websites, and offers a summary tool, flashcards, slides, an AI writer and an AI-text detector. It runs in the browser and has desktop and mobile apps.
