About

Knowingo is a guided book reading app for busy readers. Start with a clear summary, follow the ideas that matter, and ask the book when something is unclear. Explore nonfiction books through carefully prepared summaries. Each summary is organized into parts so you can follow the ideas, pause whenever you need to, and pick up where you left off. When a question comes up as you read, ask the book. The answer is based on what the book says, so you can keep reading without searching elsewhere. Lost track of a name? Tap a person in the text to see who they are and where they have appeared so far. Look up unfamiliar words without leaving the page. With Knowingo, you can: • Browse and search books by topic • Read a summary first, then follow its main ideas • Ask the book a question while you read • Tap a name to see who that person is • Look up words as you read • Resume what you were reading • Explore available research paper explainers Knowingo provides original summaries and reading guidance. It does not provide the full text of the original books. Available books, languages, questions and person cards depend on the editions published in the app. New accounts can try the reading library for seven days. After the trial, a Knowingo Reading subscription is required to read full summaries. Monthly and annual plans are available. The price is shown before you confirm a purchase. Payment is charged to your Apple Account at confirmation. The subscription renews automatically unless you cancel at least 24 hours before the current period ends. Manage or cancel your subscription in your Apple Account settings.
