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. • Playback continues with a media notification while your screen is off.
