PDF Summarizer

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.

Multi-file chats

Upload one or many PDFs into a single conversation and ask questions across all of them without switching tabs, useful for research that spans several sources.

Summaries, notes, and study aids

Get a short summary, a detailed summary, key points, notes, flashcards, and quizzes pulled from a long document in seconds.

Cross-language reading

Upload a document in one language and ask questions in another to read contracts, research papers, and reports in your preferred language.

Side-by-side source view

See your document and the chat in the same window, with answers linked to the exact passage so you can check the source immediately.
