Read full description

BookPilot is your spoiler-safe reading companion. Ask anything about the book you're reading and get clear answers based only on what you've read so far — never a word beyond your current page. Stuck on who a character is? Forgot how two people met? Want a quick recap before you pick a book back up? Just ask. BookPilot knows your exact reading position and keeps every answer inside the spoiler boundary, so you can read with confidence and never have a twist ruined again. WHY READERS LOVE BOOKPILOT • Spoiler-safe by design — the AI only ever sees what you've already read • Ask in plain language — characters, plot, themes, "what did I miss?" • A built-in library of free classics, ready to read in one tap • Bring your own books — upload EPUB or PDF files and start reading • Your progress and conversations sync so you can pick up anywhere • A clean, distraction-free reader built for long sessions HOW IT WORKS Open any book, read at your own pace, and tap Ask whenever a question comes up. BookPilot looks only at the pages up to where you are and answers from there. Read further and it keeps up — the boundary follows you. FREE TO START Read the classics and ask questions every day, for free. Upgrade to BookPilot Pro for much higher daily question limits when you want to go deeper. BOOKPILOT PRO • Monthly — $9.99 • Annual — $99.99 Pro unlocks substantially higher daily question limits.
