Desktop downloads counted since v1.1.0; Linux included from v1.3.0.WHAT IT SOLVES
Open project documentation and development notes from their existing folders. Read comfortably, edit formatted text directly, or show Markdown beside a preview. Your files stay on your own computer.
Open a Markdown file or choose a folder. Keep the existing structure, search file and folder names, and switch between documents in the sidebar.
Read headings, tables, code, and diagrams as a formatted document. Adjust text size, reading mode, palette, and light or dark appearance to suit your screen.
Click to edit text and tables without working around Markdown symbols. Choose source + preview from the editing-mode menu when you want to compare them; text wraps while deliberate scrolling keeps the panes in sync.
Reading and editing need no account or document upload. Creating a Web share link sends a temporary copy to the share service for 30 days; remote images may contact their hosts.
VERSION HISTORY
Arrange text and images in a separate layout workspace. Drag blocks into columns, resize their width, group selections, and undo changes. Paper size, typography, footer and page numbering remain controllable; your original Markdown stays unchanged.
Choose normal editing, source editing, or source with preview from one menu. Reorder document tabs when reading. Desktop code editing keeps indentation and syntax colors clear; local and shared Web images can retain GIF animation.
Desktop, Web and embedded readers share a consistent icon toolbar with immediate function hints. Reading mode is visible by default on desktop and Web. The desktop Agent CLI exports PDFs through the same layout and rendering engine.
WEB EDITION
The LumaReader reading and editing interface now runs directly in the browser. Files are read locally without upload; folder libraries, downloads, and PDF export remain desktop-only.
Open LumaReader WebDETAILED FEATURES
Supported formats, folder navigation, reading modes, rendering, editing, and interface settings are listed below.
Each desktop document shows its containing folder in the sidebar. Search file and folder names together to expand matching results, refresh the library, and check scanning or read-access notices when something is missing.
Use vertical, horizontal, or paged reading. Vertical text wraps to the available width; wide tables and code can scroll within their own blocks. Paged navigation supports left/right and up/down page turns.
Render tables, task lists, alerts, highlighted code, KaTeX mathematics, Mermaid diagrams, footnotes, emoji, abbreviations, superscript, subscript, and reusable local includes.
Create a .md in your chosen folder and edit its formatted text directly. Choose source + preview from the editing-mode menu. The Format menu explains each tool, tables have editable cells, and formatting supports undo. Unsaved changes require confirmation before leaving.
Use the share icon to enter the PDF layout workspace. Arrange columns, text and images, choose paper size and orientation, adjust typography, colored frame, footer and page numbers, then export directly. Layout edits are stored separately from Markdown.
The Settings icon brings together 11 interface languages, light and dark modes, 22 palettes, and controls for hiding individual toolbar features. Preferences stay saved, and the first-launch guide shows where to adjust them.
On macOS and Windows, choose LumaReader from Open With for .md, .markdown, .mkd, and .mdx. On Linux, run the AppImage and open a file or folder inside the app. Each file opens in an editable window, up to eight at a time. Default-app choices remain in your operating system settings.
