Nebula

Nébula is your personal, immersive reading companion — a cosmic library that lives entirely on your device.

📚 YOUR LIBRARY, YOUR WAY

Import your own EPUB ebooks and organize them into custom color-coded shelves. Track what you're reading, mark favorites, rate and review your books, and pick up exactly where you left off.

🎧 READ, LISTEN, OR SPEED-READ

Switch between traditional reading, on-device text-to-speech narration, or RSVP speed-reading mode with ambient sound — all completely offline, no internet required.

🌟 NOVA, YOUR AI READING COMPANION

Ask Nova — your cosmic owl guide — for summaries, character breakdowns, comprehension quizzes, or explanations of anything you've read. Nova never spoils what's ahead; she only knows what you've read so far.

🏆 TRACK YOUR JOURNEY

Build reading streaks, unlock achievements, and get a beautiful monthly recap of your reading habits — shareable with friends.

🔒 YOUR SECRET SHELF

Keep certain books completely hidden with a PIN-protected private vault. Only you can see what's inside.
