Ask your PDF: AI answers from your document

The blupdf AI PDF assistant reads the document you have open and answers questions from it — 'What is the notice period?', 'List every deadline', 'Summarize section 4' — with references to the pages the answer came from. Because it lives inside the editor, an answer is one click away from becoming an edit.

How it works

  1. Step 1

    Upload

    Any PDF or scan. Scanned pages are OCR'd on upload so the assistant can read them.

  2. Step 2

    Ask a question

    Type in the Ask panel. Follow-up questions keep the context of the conversation.

  3. Step 3

    Get an answer with page references

    Answers cite the pages they are drawn from; click a citation to jump to it.

  4. Step 4

    Turn answers into edits

    Found the clause that needs changing? Click the referenced block and retype it in the original font.

Why blupdf

  • Grounded in the document

    The model is instructed to answer only from the document's content and to say when the answer is not there.

  • Citations, not guesses

    Every answer points to the pages it used, so checking takes seconds.

  • Read and edit in one place

    No exporting text to a chat tool and back; the assistant works on the document you are editing.

  • Private by design

    Document text is sent to the AI provider only for your question, is not used to train models, and is deleted with the document.

Frequently asked questions

Is the assistant a substitute for reading the contract?

No. It is a fast way to locate and summarize what a document says. Verify anything you will act on against the cited page; the assistant is not legal, financial or medical advice.

Does it work on scanned PDFs?

Yes. Scanned pages are recognized with OCR on upload, and the assistant reads the recognized text.

What does a question cost?

100 credits per question. Follow-ups are questions too. Nothing is charged for reading the answer or jumping to citations.

How long can the document be?

Up to your plan's page limit. Long documents are processed in sections and answers may cite several pages.

Can it change the document by itself?

No. The assistant only answers. Changes happen when you edit a block or run AI find & replace and apply the proposals you approve.
