Cruxible
Book Summaries & Quizzes
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Turn books, PDFs, EPUBs, and articles into summaries, audio, notes, flashcards, and gamified quizzes with a cute mascot cheering you on.
Turn anything you want to understand into a guided study session.
Cruxible helps you study books, PDFs, EPUBs, articles, and complex topics in any language. Search the library, scan a cover, upload a PDF or EPUB, or start from a title, then get a clear explanation you can read or listen to.
Then Cruxible turns learning into playful practice: flashcards, gamified quizzes, instant feedback, notes, and a cute mascot that cheers you on as you go. Instead of just reading a summary, you review, test yourself, and build memory one step at a time.
Use Cruxible to:
• Understand books, articles, PDFs, EPUBs, and complex topics
• Study across languages
• Read or listen to clear explanations
• Review key ideas with flashcards
• Test yourself with quick quizzes
• Keep useful notes and insights
• Explore philosophy, history, literature, religion, politics, psychology, business, science, and more
Cruxible combines the jobs of a book summary app, audiobook player, e-reader, study notebook, and language practice tool. Read or listen, save notes, download for offline reading, review with flashcards, and test yourself with quizzes.
It is useful for students, intermediate language learners, busy readers who want to read more, lifelong learners, and readers exploring business, history, philosophy, literature, psychology, religion, politics, science, and more.
Cruxible is for curious readers, students, language learners, and lifelong learners who want reading and study to feel clearer, faster, and more memorable.
New: full EPUB support plus saved offline reading for books, PDFs, and EPUBs, with summaries, audio, notes, flashcards, and quizzes.
