Features
E-books, PDFs and comics come together in one library. Your reading position, highlights, notes and bookmarks are saved automatically; typeface, size, page colour and layout adapt to the reader.
Key features
- Library
- All books with their covers, books in progress, finished books and collections. Search by title and author; sort by recently opened, title, author or date added.
- Resume where you left off
- The reading position is saved as you turn pages; reopening a book continues from the same line, even after changing the text size.
- Highlights and notes
- Selected text can be highlighted in four colours with a note; bookmarks, highlights and notes are listed and exported as Markdown.
- Reading settings
- Paper, sepia and night page colours; the book's own typeface or serif/sans serif; text size, line spacing, margins and justification.
- Pages or scrolling
- Flowing text is split into pages, with two pages side by side on wide screens. Chapters can also be read by scrolling.
- Search in book
- Searches a word or phrase across all chapters; selecting a result opens that place with a highlight.
- Table of contents
- EPUB 3 and EPUB 2 contents, PDF outlines and FB2 sections; the current chapter is marked.
- PDFs and comics
- PDFs are read by scrolling or page by page and can be zoomed; CBZ comics fit the screen and show as double pages on wide screens.
- Reading by touch
- Tap the edges of the screen or swipe to turn the page; tap the middle to hide the toolbars.
Devices and browsers
- On phones, a library grid and a full-screen reader; settings open in a bottom sheet.

- Books are copied into this browser's storage so the library is ready every time.
