Chat with PDF: Ask & Summarize

A PDF reader that summarizes your document and answers questions with page numbers.

Get it on Google Play

What it does

AskPDF is a PDF reader that answers questions about your document. Open a PDF, tap Summarize for a short overview, or ask anything about the text. Answers come from the document itself and point to page numbers where they can; if the document does not say, the app tells you instead of guessing.

Highlights

  • One-tap summary: a one-line TL;DR plus 3 to 6 key points, in your phone’s language
  • Ask the document: type a question and get an answer based only on your PDF’s text
  • Page references: cited where possible so you can check the source
  • Open from anywhere: from your files, or via Open with or Share from email and messengers
  • Reads offline: smooth page-by-page reader, recent documents, dark theme
  • Free allowance: 3 AI actions a day, up to 20 total on the free plan, no sign-up
  • Long files: summaries and answers use roughly the first 60,000 characters of text

Made for

  • Contracts, lecture notes, research papers, manuals and reports
  • Finding one clause without scrolling fifty pages
  • Anyone who needs to understand a long file quickly

Frequently asked questions

Do I need an account?
No. AskPDF works without sign-up, and there is no paywall in front of your first question.
How many free AI actions do I get?
The free plan gives you 3 AI actions a day (a summary or a question each), up to 20 in total on the free plan. The daily counter resets every day.
Does it work with scanned PDFs?
Only if the PDF has a text layer. Image-only scans open in the reader but cannot be summarized. Password-protected PDFs cannot be opened yet.
Does reading need the internet?
No. Pages are rendered on your device and reading works offline. Summaries and questions need a connection.
Is my document stored?
The PDF file stays on your phone. When you ask for a summary or an answer, the text of the document is sent to our server and an AI model provider to produce it, and it is not stored.
What does Pro cost and add?
The free version shows ads. Pro lifts the free limits (a fair-use cap applies) and removes ads, as a weekly or yearly subscription or a one-time lifetime purchase. Cancel a subscription any time in Google Play.
