A private personal library, made your own.

Beautiful shelves for the books you bring.

Your library should feel like a place you want to return to. Bibrium presents your books as covers on wooden digital bookshelves, with depth, warm materials, and sections you can name and arrange.

Make separate bookshelves for different interests, organize books into sections, and move a book when it belongs somewhere else. Its reading place and notes stay with it.

An atmosphere for focused reading.

Read in Quiet, or choose background sounds to accompany your pages. Bibrium’s sound choices include rain, forest, night forest, fireplace, wind, underwater ambience, library focus, ancient lyre, and golden hour lofi.

Adjust the volume to suit the moment. A soft rain or a crackling fireplace can be part of your reading ritual; Quiet plays no background audio. Background sounds are a Premium feature, while Quiet is available on Free.

Make the reading environment your own.

Adapt the digital environment to your preferences: choose Ivory or Midnight for the app, pick a paper colour for the reader, set a background sound and its volume, and choose the length of your reading session.

A warm Parchment page, a bright Linen sheet, or a dark Charcoal surface gives your book a different atmosphere. Free includes basic light and dark paper; Premium includes the full paper and sound collections.

Reader Space lets you prepare for a book before opening it. Choose an intention such as reading, study, or research, set a session goal, and start or resume from your saved place.

Read your books and keep the ideas they spark.

Bring your own PDF and EPUB files to Bibrium. Open a book from its shelf, enter Reader Space, and start or resume reading in the document reader. PDF page-view options include single-page and two-page layouts.

Bookmark pages, highlight selectable text, and write personal Threads about what you are reading. Threads give your thoughts a place alongside a book or passage, so an idea does not disappear when you turn the page.

A personal library you can return to.

Your personal library is not public by default. Sign in to your account to access your books and reading progress on computers and supported tablets, with cloud sync when connected.

Previously opened books may remain readable offline when their files are cached on that device. Signing in, uploading, and downloading require a connection; do not assume every cloud book is cached for offline reading.

Account controls let you export saved information and delete your account. Library-data exports contain records and reading information; ordinary original book files can be downloaded individually from the reader.
