Smallpdf AI PDF

What it does

Chat with PDF is Smallpdf's AI document assistant. You upload a PDF and type questions in a chat box, and the AI searches the document and answers from what it finds. You can ask about names, dates, figures or topics, and reference specific pages such as page 12 to trace an answer back to its source.

The same assistant creates shorter summaries of reports, contracts, articles and study documents, and you can ask follow-up questions about sections that need more explanation. Multiple PDFs can be uploaded at once so you can ask questions across all of them, and scanned or handwritten content is read with OCR. Review important sections in the original file when accuracy matters.

It is aimed at people who work through document-heavy material for work or study. It opens in a browser on Mac, Windows, iOS or Android with nothing to install. Free use does not require an account but has usage limits, and uploaded files are deleted after one hour unless saved to a Smallpdf account.
