PDF.chat: Chat with PDF

PDF.chat lets you chat with PDF files on your Android phone. Open a PDF, ask questions in plain language, and get answers that cite the page they come from. Tap the page number and the reader jumps straight to it. It is a PDF reader, a PDF summary tool and a PDF AI assistant in one app, built for study notes, research papers, contracts, manuals and reports.

CHAT WITH PDF
Ask anything about your document: what a clause means, which method a study used, how to reset a device, what the deadline is. Answers are based on the PDF itself and show the pages they come from, so you can check every answer in the original text. Not sure where to start? Suggested questions help you begin.

SUMMARIZE PDF
• A short summary appears automatically, so you know what a document is about before you read it.
• Ask for a detailed PDF summary whenever you need one, with page citations for each point.

AI PDF READER AND PDF VIEWER
• Pages are rendered on your phone, with smooth continuous scrolling.
• Pinch to zoom, or double tap to zoom in on a passage.
• Browse a grid of page thumbnails, or go straight to any page.
• Reading works offline, with no connection needed.

FIND IN DOCUMENT
Search the text of your PDF on the phone and jump to each page where your words appear.

SCANNED PDF SUPPORT
PDFs without a text layer still work. Scanned pages are read on your phone with on-device text recognition for Latin-script languages, so you can search a scanned PDF and ask questions about it too.

OPEN PDFS YOUR WAY
• Pick one or several PDFs at once from your files.
• Share a PDF to PDF.chat from any other app.
• Use "Open with" from a file manager, an email attachment or your downloads.

YOUR PDF LIBRARY
• Keep many documents on your phone and open them offline.
• Search your library by title or by the text inside each document.
• Each document keeps its own chat history on your phone.

COPY, SHARE AND EXPORT
• Copy or share any answer in one tap.
• Export a chat as a text file, or as a PDF made on your phone.
• Export the extracted text of a document.

USEFUL FOR
Students turning lecture slides and textbooks into study notes. Researchers reading research papers and checking methods and results. Anyone reviewing contracts, leases and policies before signing. Owners looking up an answer in long manuals. Professionals working through reports, specifications and meeting papers.

PRIVACY: WHAT STAYS ON YOUR PHONE
• The text of your PDF is extracted on your phone.
• Only that text and its page numbers are sent to pdf.chat to answer questions and write summaries. The PDF file itself is never uploaded.
• Your documents, library and chat history are stored on your phone.
• Every AI answer has a Report button, so you can flag an answer that is wrong or harmful.
• You can delete your account from inside the app.

ACCOUNTS AND PLANS
You can start without an account and ask questions within a daily allowance. Create an account or sign in from inside the app to get a monthly allowance as well. When you need more, plans and one-time page packs are available through Google Play billing. Pages are used to read documents and to answer questions. Plans renew through Google Play and are managed or cancelled there, and purchases can be restored on your account.

LANGUAGES
The app interface is available in many languages, and you can ask questions about your PDF in your own words.
