Welcome to ThreadMark, the ultimate local-first Markdown reader that transforms your personal notes, development logs, and reading materials into an immersive, thread-style reading experience! Whether you're organizing a massive "Second Brain" or simply jotting down grocery lists, ThreadMark makes reading long documents on mobile incredibly fast, casual, and stress-free. β–  What is ThreadMark? ThreadMark is a unique Markdown viewer and editor that parses your local files into a message board/forum structure. Simply select your local folder (Vault), and the app automatically treats your folders as "Boards", your .md files as "Threads", and paragraphs divided by headings as numbered "Posts". β–  Who is this for? - Heavy Markdown users looking for a lightweight, mobile-friendly way to browse their vast knowledge base. - Users of desktop-based PKM (Personal Knowledge Management) tools who want a seamless, local mobile companion. - Anyone who loves the scrollable, bite-sized reading experience of timelines and forum threads. - Privacy advocates who prefer 100% offline, local storage without cloud lock-in. β–  Key Features - Innovative Thread-Style UI Documents are automatically split based on headings (e.g., ##) and displayed as numbered posts. Even a 10,000-word document becomes as easy to digest as scrolling through a social media feed. - Rich Markdown Compatibility Fully supports WikiLinks ([[Note Name]]) for bidirectional linking. Tap a dead link to instantly create a new thread. It also beautifully renders inline images, transclusions (embedding other .md files), and callouts (e.g., > [!info]). - Powerful "Quote Anchors" Navigate complex thoughts instantly. Type >>1, >>1-5, or >>1,3 to create interactive anchors. Tapping them opens a quick pop-up preview of the referenced sections without losing your scroll position. - 100% Local & Secure No accounts, no logins, and no forced cloud syncing. All data remains safely on your device's local storage, ensuring your private diaries and sensitive technical notes stay truly private. β–  Rich Customization - Dual Viewing Modes Switch seamlessly between the immersive "BBS Mode" (Board/Thread/Post layout) and the traditional "Standard Mode" (Folder/Note layout) depending on your mood. - Beautiful Themes & Typography Choose from a variety of carefully crafted themes, including a classic Retro Beige, pure Dark Mode, Dracula, and Cyberpunk. Includes a precise font scaler to build your perfect reading environment. * Note: ThreadMark is free to use with optional ads. We offer a one-time lifetime purchase to remove ads completely, or you can temporarily hide ads for 6 hours by watching a short video. * Note: This app is a local file viewer/editor. It does not connect to or browse external internet forum services.
