Upload EPUB, Parse in Background
Drop an EPUB on the shelf. Cover, metadata and chapters are parsed in a background job, so you can keep uploading instead of waiting on one book.
INGEST · 01Upload the books you already own, read them in the browser, and select any word to look it up — progress and vocabulary stay with your account.
Everything you need to read a book end to end, and nothing that gets in the way.

INGEST · 01Find a book by title or author and sort by recent reading. With dozens of books on the shelf, browsing stays fast.
SHELF · 02Progress is stored per chapter as well as for the whole book. Progress only moves forward, so flipping back a page never erases how far you have read.
READER · 03Select a word and get its dictionary entry with roots, affixes and official dictionary links — inflected forms are folded back to the base word first.
LOOKUP · 04Send a selection to your language-learning articles or append it to an existing one, so reading and vocabulary practice live in the same place.
STUDY · 05Instead of copying a word into another tab and losing the thread, look it up in place — then keep the sentence as a lesson if it is worth revisiting.
The EPUB files and every reading position belong to your account. Shelves are never shared and never listed publicly.
Chapter-level progress, in-book lookup and exportable passages make it a place to actually read, not just to store files.
It runs in the browser on the same account as the rest of Fly2x — no sync client, no second install.
Sign in and upload an EPUB — parsing starts right away, and your reading position is saved from the first page.
