When you need help unpacking a difficult section, Libris offers in-context AI explanations inside the book youβre reading, so clarification stays grounded in the text instead of drifting into generic chat. Libris is built for deep reading, re-engagement, and memory by choice. Notes remain user-authored. AI supports understanding, but your ideas stay your own. Features: Import and organize EPUB books in a personal library Read in a clean, distraction-aware reader Highlight passages and revisit them later Write notes scoped to each book Ask for AI explanations in the context of the current book Search your reading and return to important material over time
Kravion

You read a lot. But what's left a week later? Kravion helps you keep the ideas that matter to you. Read, keep the one idea, and Kravion brings it back until it sticks. HOW IT WORKS β’ Read a book (almost any book, by search or ISBN), then talk with Ethan, your reading partner, about what moved you. β’ Keep the idea you want to remember, in your own words. Something Ethan said worth keeping? Save it as Ethan's line. β’ Kravion asks it again as a short question: after 1 day, 3 days, 1 week, 2 weeks, 1 month. β’ Still know it? It comes back later. Not yet? It comes back soon. REMEMBER, DON'T REREAD β’ Remember first, then reveal. Your own words show how close you were. β’ Nothing comes? A hint, not the answer. β’ Five ideas at a time, a few minutes a day. No endless feed. WHAT MATTERS FIRST β’ A book's core ideas and your own line from the book ("My line from this book") come before side notes. β’ See what sticks: the ideas you've kept and what's waiting now. YOUR NEXT BOOK β’ One pick for your next book. REMINDERS AND START β’ Reminders only if you want them, at most one a day. β’ Free to start, no account needed to begin. In English and German. Keep what you read.
