AI book notes that don't stop at the summary. Read a chapter, reflect, commit to one action, then review whether you did it. Kravion is a reading companion for nonfiction. One idea per sitting, one honest reflection, one concrete step in your week, then a check on what actually happened. That loop is the whole product. THE BEHAVIOR LOOP Read a chapter. Reflect with your AI companion. Commit to one small action. Review whether you followed through. Open the next session from that result, not from a streak. CHAPTER CHAT After each chapter, talk to a companion that knows the text and your past notes. Challenge the idea. Get a one-line take. Ask what it means for this week. ATOMIC NOTES Save the useful ideas as small, linked notes. Connect them across books. Build a library you can actually query. BOOKS AND PODCASTS Keep titles and shows on one shelf. Reflect on an episode the same way you reflect on a chapter. YOUR KRAVION SCORE Not a streak you can lose. A private score of sessions read, reflections written, and actions reviewed. Missing a day does not erase the work. PRIVATE BY DEFAULT No account needed for your first book. Notes stay on your iPhone. Works offline. Cloud backup is optional, on Premium. Free to start. Upgrade only if the loop earns it. Cancel anytime. Kravion is for people who have already read Atomic Habits, Deep Work, and The Psychology of Money, and want those books to show up in the week, not only in Highlights. Not what you read. What you do next.
