PaperReader: AI Reader

PaperReader is your AI reading and study workspace for iPad.

Bring any source — a web page, a PDF, a document, or pasted text. Read it on the left, work with AI on the right, and annotate anything with Apple Pencil. PaperReader is a helper while you read, not a background bot.

WHAT YOU CAN DO • Summaries that frame the big idea and the takeaway • Annotated reading: the faithful text with an AI explanation layer • Translation into 30+ languages, structure preserved • Source-grounded chat — ask questions, get answers from your source • Flashcards and a glossary generated from what you read (spaced repetition) • On-device semantic search across your library

MADE FOR APPLE PENCIL • A transparent drawing layer on every block, aligned to the content • Free-position text boxes, stamps, and reactions

BRING YOUR OWN AI KEY PaperReader works with your own API key from Anthropic, Google Gemini, OpenAI, or Groq. We don't sell AI credits — your text goes directly to the provider you choose, and you're asked before anything is sent.

PRIVACY BY DESIGN No servers of ours, no analytics, no tracking. Your library lives on your device and your iCloud.

FREE & PRO Add up to 10 sources for free. PaperReader Pro (monthly or yearly) removes the limit.

AI features require your own AI provider API key.
