AI PDF & EPUB Reader: PageSage

Active reading, on every page. Now with offline AI. PageSage reads PDFs and EPUBs the way serious readers need: tap any word for an instant definition, save it for spaced repetition review, listen with realistic neural voices, or ask the on-device AI to explain, summarise, or quiz you on what you just read. No internet required. No cloud. No subscription.

WHAT PAGESAGE REFUSES TO DO

• No ads. Not now, not ever.
• No subscriptions. Free to read forever.
• No account or sign-up required. Open the app and start reading.
• No license checks. Works offline forever, even on flights.
• No "All files access" permission. We only see files you choose to import.
• Deleting a book from your PageSage library never deletes the file from your phone.
• Your purchase follows your Google account. Restore on any device, anytime.

ON-DEVICE AI (NEW IN V1.3)

• Tap Explain on any highlighted passage: a 2-4 sentence breakdown in plain English.
• Summarise any page in 2-3 sentences, or extract key points as bullets.
• Generate practice Q&A from any page to test your understanding.
• Runs 100% on your phone. No internet after the one-time setup. No subscription.

READING THAT JUST WORKS

• PDF and EPUB support: novels, ebooks, textbooks, and documents in one library.
• Tap any word for an offline dictionary with definitions, pronunciation, synonyms, and part of speech.
• Reader Mode reformats dense PDFs into a clean, distraction-free reading view.
• Focus Beam dims everything except one reading strip, one line at a time: ideal for concentration, dyslexia, and eye fatigue.
• Highlight in 4 colours and place bookmarks.
• Four reading themes (Classic, Midnight, Forest, Cream) for any time of day.
• Vertical scroll or traditional page-flip animations.

LISTEN TO ANY BOOK (READ ALOUD)

• Realistic on-device neural voices for any PDF or EPUB. Works fully offline after a one-time download.
• Three voices: Supertonic (10 modes: calm, cheerful, authoritative, warm, and more), LJSpeech, and Lessac.
• Or use your device's built-in TTS engine, free.
• Pages auto-advance to keep pace with playback.
• Adjustable speed from 0.5x to 2x.
