What is PDF Assistant?
This assistant combines two helpers. Leave the question empty to get a summary of the key sentences, or type a question to receive the matching passages with page numbers. Everything runs locally in your browser.
How to get answers from a PDF
- Upload a text-based PDF.
- Type a question, or leave the box empty for a summary.
- If you want a summary, choose short, medium or long.
- Press Start and read the result.

Tips for better results
The assistant selects existing sentences; it does not write new text. For scanned files run OCR PDF first. Verify important details in the source.
Good to know before you start
Think of this tool as two helpers in one box. With the question field empty, it chooses the highest scoring sentences from the whole document and lists them with page numbers in the length you picked. With a question typed in, it searches the text for the passages that best match your keywords and shows those instead. Both modes run on your device with simple text analysis, without generating new wording, so what you see is always taken from your own document. Use it to get oriented in a long report, then switch to a targeted question to find a specific detail. Because the page numbers are included, you can jump straight to the source in your PDF viewer and read the surrounding text before you rely on a result. This is especially useful for contracts, manuals and research papers, where context matters.
