Lumen Read - EPUB Reader & Reading Tracker автор Zolangui

Stop abandoning your books.

Lumen Read turns your browser into a private, distraction-free EPUB reader designed to make reading comfortable, consistent, and personal.

• Import and read local EPUB books directly in your browser.
• Customize fonts, font size, line height, spacing, themes, and layout.
• Apply reading preferences globally or customize them for a single book.
• Use dark mode, full-screen reading, and Zen Mode for focused sessions.
• Keep book covers and illustrations visually balanced in dark themes.

• Navigate with a table of contents, reading timeline, and chapter controls.
• Search across book chapters.
• View reading progress, estimated pages, reading speed, and time remaining.
• Highlight passages, write notes, and manage your personal library.
• Quickly switch between books you already have open.

• Track daily activity with a GitHub-style reading heatmap.
• Follow your reading streak and progress over time.
• Use reading insights to understand your pace and establish a consistent habit.

Lumen Read includes an optional book-aware assistant that can retrieve relevant excerpts, answer questions about the current book, and help rewrite selected text.

AI is always opt-in. You choose the provider and model, explicitly allow the connection, and can use compatible local models. Your API key is not stored in browser local storage.


Your books and ordinary reading data stay in your browser storage by default. Lumen Read does not run Sentry telemetry in published extension builds.

Optional AI and Dropbox features only connect after your explicit action and use the provider you select.

Lumen Read is free and open source under the AGPL-3.0 license. It is an enhanced fork of the Flow reader project.
