What it does

A focused reader that stays out of your way

Any format Bring any book

Convert EPUB, TXT, Markdown, or HTML into reader files in the browser — or drop them straight on the SD card.

Languages Japanese, Chinese & Korean

Pick your reading language when you flash: bundled font, translated menus, switch any time.

Wireless Sync without cables

Send books, articles, and RSS feeds to the reader over Wi-Fi from any browser — no app to install.

New reader, empty card? Load a famous public-domain classic straight into the workspace below, then sync it to your SD card. Every title is free and converted offline — sourced from Project Gutenberg and Aozora Bunko.

    Bring books into the browser, convert them into .rsvp, and sync the results back into the SD card’s /books/books folder without leaving this page.

    Compatibility Preserves your book's characters

    Keeps accented, Baltic, Sami, and other extended-Latin letters — and passes Japanese, Chinese, and Korean text straight through for the reader's fonts.

    Selected Folder No /books/books folder selected
    Library Summary 0 converted books ready
    Folder Inventory Pick the SD card’s /books/books folder to scan it
    Ready to build a library Connect your SD card, or add books from your computer, to bring supported source books into the workspace.

    Converted Books

    Each imported source is turned into a reader-ready .rsvp file so you can download it or sync everything back to the selected folder in one step.

      Add a few books and the converted library will appear here.
