Library
Your ebooks sorted, found, and never rewritten.
A library is built by dropping files. Everything else, search, series, versions, happens from each book’s page, without touching the text of the original file.
Drop, and let it check.
Up to 1,000 files per import, processed ten at a time, 512 MiB per file. Accepted formats: EPUB, MOBI, AZW3, TXT, HTML, FB2. The fingerprint is computed in the browser, the server checks the stored bytes before publishing the book, and an exact duplicate is recognized instead of being added twice. An interrupted import resumes when you select the same file again.
Search the way you remember.
Title, author, series, number, book language, genre, format, edition, metadata status, size, favorites, rating, progress, presence on a device: filters stack. Sorts stay in the URL, pagination keeps a stable order. Grid or table, your call.
One series, every volume, in one place.
The Series page groups the volumes and filters them by language and edition. A volume split in parts and a complete edition keep their differences. Below the list, three on-demand checks, no AI key needed: missing volumes, duplicates, your library in numbers.
Collections and saved views.
A collection is a group of books you name; every member of the space sees it, 200 collections per space, 5,000 books per collection. A saved view keeps your filters, sort and layout under a name; only you see it, 50 per space. An OPDS e-reader finds the collections in its catalog.
The Currently reading shelf.
On the first page, with no filter, up to six books started and not finished, most recently read first, whether you opened them in the browser or on a synced e-reader. Resume opens the reader.
The right file for every e-reader.
From the book’s page, pick a ready source file and an output: EPUB, TXT, HTML, MOBI or AZW3. Three profiles: lossless, small Xteink reader, text only. If a profile drops images, you know before you start. The result is a new version, with its size and the measured gain; the original doesn’t move. FB2 can be imported, not produced.
Trash, then restore.
A book sent to the trash leaves the lists and frees a slot of your plan; its files, versions and your progress are kept. Restoring checks the quota and conflicts before putting it back. The trash never deletes a file already copied to an e-reader.
Before your first import
Do I need to install Calibre?
No, the library runs in your browser. For a USB e-reader or an SD card, open its folder in a compatible browser and grant the permissions it asks for.
What happens to the original file?
Its text stays intact. When you correct the title, the author or the series, that metadata is written into the file so that your e-reader shows it, and the file as imported remains downloadable for 30 days. An optimization creates a separate version with its own history.
How are books counted across my workspaces?
Every plan includes unlimited workspaces. Your account quota adds up the active books you own across all of them, plus slots reserved by imports. Versions of the same book don’t take an extra slot. Books lent to you don’t count; books you lend out still count on your side.
