Markdown Parser

A tiny, local-first Markdown viewer for Android and Windows.
No cloud, no ads, no tracking, no "rate me" popups, no auto-update nagging.

Heads-up
The app UI is hardcoded in Simplified Chinese. Text strings are minimal (打开文档, 演示文档) and the bundled demo document is also Chinese. The Markdown parsing, rendering, and all features work on documents in any language. If a Chinese UI is a deal-breaker for you, please do not install.

Anti-features (intentional)
