PDF Summarizer is an AI document assistant that lets you upload PDFs and other files, then chat with them to get summaries, key points, detailed overviews, notes, flashcards, and quizzes. You can add several documents to one conversation, ask questions across them, request answers in any language, and click through to the source passage in a side-by-side view instead of reading every page yourself.
