Local Thread-Style Reader
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Read local Markdown files like message threads! ThreadMark turns your notes into an immersive offline forum. Supports WikiLinks & quote anchors. Fast and secure.
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.
■ 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".
■ 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.
■ 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.
■ 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.
