PaperReader: PDF Summarizer

Bring a web page, PDF, or text; let AI summarize, annotate, and translate it. Take notes on top with Apple Pencil. Your own API key, your data stays yours.

PaperReader is your AI-powered reading and study space for iPad.

Bring your own source — a web page, a PDF, a document, or text you paste. Read on the left, work with AI on the right, and write over any of it with Apple Pencil. PaperReader helps while you read; it is not a bot that harvests in the background.

WHAT YOU CAN DO • Summaries framed by the main idea and the conclusion • Annotated reading: an AI explanation layer over the faithful text • Translation into up to 30 languages with structure preserved, including tables and lists • Source-grounded chat — answers your questions from your own source; open it to general knowledge when you like, and general answers are clearly marked • Flashcards and a glossary generated from what you read (in Learning Cards) • Bookmarks — the spots you mark while reading are collected with their tags in a single list; filter by notebook, tag, or search, and one tap takes you back to that exact line • On-device semantic search across your library

FOR APPLE PENCIL • A transparent drawing layer over every block, aligned to the content • Freely placed text boxes, stamps, numbers, and reactions • Press and hold on the canvas and your stamp, emoji, number, text box, or bookmark lands exactly where you touched

YOUR OWN AI KEY PaperReader works with your own API key for Anthropic, Google Gemini, OpenAI, or Groq. We don't sell AI credits — your text goes directly to the provider you choose, and you are asked to approve every submission.

PRIVACY BY DESIGN We have no servers, no analytics, no tracking. Your library stays on your device and in your iCloud.

FREE & PRO 10 sources free. PaperReader Pro (monthly/yearly) removes the limit.

AI features require your own provider API key.
