Description
**Markdown, as a document
**Markdown, as a document.** Luma is a lightweight, quiet Markdown editor for macOS. Open plain files from your disk, write without a source/preview split, and keep everything local. Tables look like tables. Diagrams look like diagrams. You can focus on the document even if you do not think in Markdown syntax. -------------------------------- ■ Write Markdown without living in syntax Headings look like headings, bold text looks bold, and tables appear as real tables as you type. Your files stay as ordinary `.md` files, so you can reopen them in any other Markdown tool whenever you want. ■ Paste tables straight from Excel Copy a cell range from Excel, Numbers, or Google Sheets, then paste it into Luma. The clipboard content becomes a clean Markdown table automatically. No more drawing pipes and dashes by hand. ■ Turn Mermaid code into readable diagrams Write a fenced `mermaid` code block and Luma renders it as a colorful diagram right away. Flowcharts, sequence diagrams, Gantt charts, pie charts, class diagrams, and state diagrams all work without opening another app. ■ Edit tables like tables Use Tab and Shift+Tab to move between cells. Press Tab in the last cell and Luma adds a new row. When the cursor is inside a table, a small table toolbar appears so you can add or remove rows and columns quickly. ■ Make the page feel yours Adjust the body font, text size, page width, and per-heading styles from one settings panel. Choose from the fonts already installed on your Mac, and tune the page until it feels right for the way you write. ■ Local, offline, and private Luma does not connect to the internet. There is no account, no cloud sync, and no analytics. Your documents remain on your disk, and every feature works offline. ■ Built for macOS habits Open `.md` and `.markdown` files directly from Finder. Use familiar shortcuts: Command-O to open, Command-S to save, and Command-Comma to open settings. Luma supports both light and dark appearance. -------------------------------- ■ Great for · Blog posts, technical notes, and release notes · Product and planning docs with tables or diagrams · README files and operational docs you want to edit without an IDE · AI-generated Markdown that needs a clean human pass · Writers who want a small, focused tool instead of a full note system ■ Key features · Live document-style Markdown editing · GitHub Flavored Markdown support · Headings, lists, quotes, code blocks, links, images, and tables · YAML front matter preservation · Mermaid diagram preview for flowcharts, sequence, Gantt, pie, class, and state diagrams · Automatic Markdown table conversion from Excel, Numbers, and Google Sheets · Table tools for adding and deleting rows or columns · Tab and Shift+Tab cell navigation · Automatic row creation at the end of a table · Custom body font, text size, page width, and heading styles · macOS system font picker · `.md` and `.markdown` file association · External file change detection and conflict handling · Automatic light and dark mode · 100% local: no network, no account, no analytics ■ What Luma is not trying to be Luma does not include note graphs, backlinks, plugins, cloud sync, or collaborative editing. If you need a full knowledge base system, a larger notes app may be a better fit. Luma keeps that space empty so it can stay fast, calm, and focused on one plain document at a time. ■ System requirements · macOS 12 Monterey or later · Apple Silicon Mac support ■ Made by Waymaker Labs Luma is made by Waymaker Labs, a small software studio in South Korea.
