You can also create characters, add your own notes and relationships, and quickly find them again as you continue reading. BookWyrm currently supports English books.

Your library stays on your server. Klibri just reads it. Klibri needs a Kavita server you already run. It doesn't host or sell content of its own. READ EVERY FORMAT Manga and comics (CBZ, CBR), e-books (EPUB) and documents (PDF) — one app for your entire library. BUILT FOR COMICS AND MANGA Pinch to zoom, double-tap, swipe or tap the edges to turn pages. Read left-to-right or right-to-left. Read long strips in continuous webtoon mode. Adjust screen brightness without leaving the page. A REAL BOOK READER The EPUB reader gives you four themes (including a true-black mode for OLED), six fonts, and fine control over size, spacing and margins. Read in scrolling or paged mode, and search the full text of any book. READ OFFLINE Download chapters and read them anywhere — no connection needed. PDFs render fully offline. PICK UP WHERE YOU LEFT OFF Klibri syncs your reading progress with your Kavita server in real time. Move from iPhone to iPad, or to Kavita in a browser, and carry on at the exact page. Klibri won't overwrite progress you've made elsewhere. YOUR WHOLE LIBRARY Browse series, collections and reading lists. Search your entire library, even a large one. Mark chapters or whole series as read. ALL YOUR KAVITA SERVERS Add more than one Kavita server and switch between them in a tap. Each server keeps its own libraries and its own reading progress.
