What you get
A reader, not a reading service
Your whole shelf
Every book you add, listed with author and how far in you are.
Chapters, not files
The table of contents is parsed out of the book, so you navigate by chapter.
Picks up where you stopped
Chapter and scroll position are both remembered, per book.
Typography you own
Serif, sans, mono or dyslexia-friendly, at the size and rhythm you want.
Two-page columns
Flow the chapter into newspaper columns when the window is wide.
Images and comics
Cover art and embedded illustrations render inline, CBZ pages included.
Offline by default
Once a book is in, it opens with the network switched off.
Nothing phones home
No account, no analytics, no upload. The file never leaves the device.
Reading themes
Paper for the hour you are reading in
Five presets built in, or pick your own background and ink. The same set ships in the editor extension.

Warm Ivory
Classic Sepia
Dark Parchment
OLED Midnight
In your editor
Ships as an extension, too
Install the VSIX and the same library lands in your sidebar: a scrolling reader panel under the book list, chapters that open as real editor tabs, and a settings page that restyles both as you drag. It is a plain VS Code extension, so the forks take it unchanged.

Your shelf
A library that never leaves your machine
Drop in your files and they are parsed on the spot, then kept in your browser's own storage. Close the tab, come back next week, and the shelf — and the page you stopped on — are still there.
Your typography
Set the page to your eyes, not a designer's
Serif, sans, mono or a dyslexia-friendly face. Size, weight, line height, letter spacing, margins, columns, and a reading theme for the time of day. Every change lands in the page as you make it.
Built in the open
A reader you can read the source of
Same reader on the web and inside VS Code. Both are open source — read the parser, file an issue, or take it apart and make your own.
