klibrary is a free macOS app for readers who take notes to replace the default MacOS Books app. Read EPUB, PDF, MOBI and AZW3, mark passages in colors you define, and write what you want to keep in mind. Every note stays searchable across your whole library — no account, no cloud, nothing uploaded. It brings you experience of reading, taking notes and organizing them in one place.
