Keep the books you have read on a wooden shelf, cover out, together with what you thought while reading them. - Type a title and the cover, author and publisher are filled in for you - Four views: shelf, spines, list and cards - Three kinds of notes (thoughts, summaries and quotes), each with a page number - Full-text search across every note, title, author and publisher - To-read, reading and finished, with 5-star ratings - When you finish a book, see other books by the same author on Rakuten Books (ad links) - Reading stats: books finished this year and the authors you read most - Export to Markdown (one file per book, handy for Obsidian) or CSV (for Notion), and restore from a backup file - No account and no email address needed. Your notes stay on your device Please note - Covers and book data come from Rakuten Books (Supported by Rakuten Developers). Lookup may be temporarily unavailable when busy, and books published outside Japan are often not found. You can always set a cover from your own photo, and your books and notes are never lost
