How to Chat with a PDF: Ask Your Document Questions

Most of the time you do not need the whole document, you need one answer that is in it: the notice period in a contract, the setting in a manual, the definition in chapter four. Searching for a keyword finds the word, not the answer. Here is how to ask a PDF a question in plain language instead.

1 min read4 stepsUpdated October 27, 2026By the NoteBase team
  1. Turn the PDF into a note

    Upload the PDF on the Convert PDF & Images to Text page, or take a photo of a printed page. NoteBase reads the text, including scanned pages, and saves the document as a note with a summary on top.

  2. Open the chat and ask

    Open the AI chat on the note and type your question the way you would ask a colleague who has read the document. The answer is written from the document's own text, so it uses its terms and its numbers rather than general knowledge.

    • "What is the cancellation notice period?"
    • "Which settings do I need to change before the first use?"
    • "Explain the difference between the two methods in section 3."
    • "List every deadline in this document."
  3. Follow up until it is clear

    The chat keeps the conversation, so a follow-up can build on the last answer: ask for an example, a simpler explanation or the same answer as a checklist.

  4. Use the same chat on any note

    The chat is not only for PDFs. It works the same way on a lecture recording, a meeting transcript or a YouTube video, so one habit covers every kind of material you save in NoteBase.

Questions about this guide

Does the AI make up answers that are not in the document?

It answers from the note's text. When something is not in the document, ask it to say so - and check important answers against the page, as you would with any summary.

Can I chat with a scanned PDF?

Yes. The text is read from the page images first, so a scan works like a digital PDF.

Is the chat available on the free plan?

Yes, with a limited number of messages; NoteBase PRO removes the limit.
