Chat with PDF

Ask your reading anything

Upload a PDF of lecture notes, a chapter or a paper and ask it questions in plain language. Get summaries, key points and explanations drawn from the document itself.

Why students use it

Understand long readings in a fraction of the time

  • Ask in plain language

    Ask about a definition, a paragraph or a whole chapter the way you would ask a classmate, and follow up until it makes sense.

  • Summaries and key points

    One click turns a long reading into a summary or a list of key takeaways, so you know what matters before you dive in.

  • Answers from your document

    Responses are grounded in the file you uploaded, not the whole internet, so they match what your course actually assigns.

  • Read and chat side by side

    The PDF stays open next to the conversation. Highlight passages as you go and come back to them later.

  • Quiz me

    Ask for a quick quiz on the document to check that you understood it, not just read it.

  • Turn it into flashcards

    When you are done reading, generate a flashcard deck from the same document and start reviewing.

FAQ

Document chat questions

Need notes to start from? Browse the study library.

How does chatting with a PDF work?

Upload a PDF and CramX reads it. You then ask questions in plain language and get answers based on that document, with the PDF open beside the chat so you can check the source.

What kinds of documents work best?

Text-based PDFs such as lecture notes, textbook chapters, articles, research papers and study guides. Scanned pages without selectable text may give weaker results.

Is it free?

You can start free: new accounts get 50 points and starting a chat costs 5 points, with longer conversations using a few more. Premium plans include unlimited document chat.

Can it summarize a long reading?

Yes. Use Summarize or Key points for a quick overview, or ask for a summary of a specific section or chapter.

How accurate are the answers?

Answers are based on your document, which keeps them on topic, but AI can still misread a passage. Check anything important against the page itself.

Are my documents private?

Yes. Files you upload for chat are private to your account unless you choose to share a document to the study library.

That 40-page reading won’t summarize itself

Upload it, ask what matters, and walk into class prepared.
