Markdownfinder

The product is a native reader for Mac, iPhone, and iPad that browses, previews, and searches folders of Markdown files, rendering Mermaid diagrams, math, callouts, and frontmatter without requiring setup or an account. It is for individuals who work with Markdown-heavy folders such as AI exports, notes, and documentation and need to quickly find and read files. It is positioned as a file-first reader rather than an editor, delivered as a local, offline universal purchase with a free tier and a one-time paid upgrade.
