QingMo is a cross-platform Markdown editor built for a smooth writing flow. Edit on the left, see the rendered result on the right in real time — no more switching back and forth between syntax and output. — Live Preview — Rendering kicks in the moment you stop typing, with millisecond response. Switch freely between source, split, and preview modes. In split mode the editor and preview scroll in sync, so you never lose your place in long documents. — Navigate Long Documents — - Minimap: a structural overview on the right edge, color-coded by headings, body, and code. Click or drag to jump — accurate even with soft wrapping. - Sticky Header: keeps the full heading path of your current position pinned at the top while scrolling; click any level to jump back. - Two-way Linked Highlight: select text on one side and the matching text on the other is highlighted automatically. (All optional, toggleable in Settings, off by default.) — Full Markdown Support — - CommonMark: headings, emphasis, lists, quotes, links, images, rules - GitHub Flavored Markdown: tables, task lists, strikethrough, autolinks - KaTeX math: inline $...$ and block $$...$$, rendered offline - Superscript and subscript for chemical formulas and math notes - Syntax highlighting for dozens of languages: Python, Swift, Rust, Go, Java, JavaScript, SQL, and more — Fast Input — One-tap toolbar for bold, headings, lists, tables, formulas and more.

Full keyboard shortcuts for external keyboard users. — Consistent Across Devices + iCloud Sync — iPhone, iPad, and Mac share the same rendering core for consistent results everywhere. Turn on iCloud and your documents sync automatically across devices signed in to your Apple ID. — Handy File Management — A built-in file explorer: create, rename, delete, duplicate, and drag items into folders. Export to PDF or a single self-contained HTML file for easy sharing and archiving. — Privacy First — QingMo collects no personal data and contains no ads or trackers.
