Difficult books are worth reading. Dense prose, unfamiliar ideas, and older language should not keep great books out of reach. Clarify is an AI ebook reader for iPhone and iPad that helps you understand challenging books without leaving the page. Browse 100+ included classics, follow a guided philosophy path, or import your own EPUB. Read the original—not a summary. Ask for help only when you need it, compare clearer wording with the original, and keep reading. AUTO SIMPLIFY AS YOU READ Turn on Simplify and clearer wording appears directly in the reader as you move through the book. Clarify works progressively, paragraph by paragraph, and is designed to preserve the book’s structure and formatting. The original text is always one tap away. SIMPLIFY A PASSAGE Select a difficult sentence or part of a paragraph to see the same idea in clearer language. Switch between the simplified version and the original whenever you want. EXPLAIN THE IDEA Need more than a rewrite? Select a passage for a short answer followed by a fuller explanation informed by nearby text and book context. Understand the idea—not just the words. 100+ CLASSICS—OR YOUR OWN BOOKS Browse and download more than 100 classics across fiction, science, philosophy, history, poetry, adventure, and drama. Already have something you want to understand? Import your own EPUB files and use the same Simplify and Explain tools. GUIDED PHILOSOPHY PATHS Not sure where to begin? Clarify recommends a starting book and related works to explore next: • Understand Stoicism—six essential works featuring Marcus Aurelius, Epictetus, and Seneca • Ethics & the Good Life • Power & Government MADE FOR FOCUSED READING • Reading progress saved automatically • Table of contents and chapter navigation • Adjustable text size • Light, dark, and system themes • Downloaded and imported books stored on your device • Core reading works offline • No account required Stay with the original. Get help when you need it. Keep reading.
