MarkTome

MarkTome is a local-first Markdown workspace built for long documents. It brings real file management, structured navigation, safe editing, offline math typesetting, and professional export into one focused mobile workflow. No account is required—open or create a Markdown file and start working. LONG-DOCUMENT NAVIGATION • Create, open, rename, and duplicate real Markdown files in a local library • Search, collapse, and jump through multi-level heading outlines • Keep the current section synchronized between reading and source editing • Detect skipped heading levels, duplicate headings, and unusually long sections • Jump directly from each structure issue to the affected heading RELIABLE EDITING AND FILE SAFETY • Edit with a native text editor designed for selection, undo, and long-document scrolling • Track autosave states: waiting, saving, saved, and failed • Preserve UTF-8, UTF-16, BOM, and original line-ending styles • Save real files using coordinated access and atomic replacement • Pause saving when an external change is detected, then reload or preserve the local edit • Keep recovery copies after save failures or conflicts READING, MATH, SEARCH, AND DELIVERY • Render GitHub Flavored Markdown entirely on device • Display headings, lists, tasks, quotes, code blocks, tables, links, and images • Typeset inline and display math offline with bundled KaTeX • Support $...$, $$...$$, \(...\), and \[...\] math delimiters • Use system Find in both reading and editing modes • Generate A4 PDFs on device and deliver them through the system share sheet • Support Dark Mode, Dynamic Type, landscape, Reduce Motion, and VoiceOver PRIVACY MarkTome requires no account and includes no advertising, behavioral analytics, or developer tracking. Document content, outline analysis, math rendering, search, and PDF generation happen on device. Remote images referenced by a Markdown file may load from their original hosts.
