A polished, full-featured Markdown reader: drop in a local folder and start reading, with Mermaid, KaTeX, syntax highlighting, full-text search and outline navigation.
You can also drag a folder or a .md file onto this page · press O to open a folder · ? for all shortcuts
KaTeX renders inline $E=mc^2$ and display formulas, including matrices, alignment environments and common chemistry macros.
Mermaid flowcharts, sequence, class, state, Gantt, pie, ER and mind-map diagrams, recoloured automatically with the theme.
Highlighting for all mainstream languages, with line numbers, soft wrapping, collapsing of long blocks and one-click copy.
GFM tables gain click-to-sort headers and horizontal scrolling, so wide tables never break the layout.
Builds an offline index over the whole folder, fuzzy-matching titles and body text and highlighting every hit.
Relative image paths in Markdown resolve automatically; click to enlarge, drag to pan and scroll to zoom.
Dark mode, adjustable type size, line height and column width, a serif toggle, reading progress and position memory.
Write Markdown on the left, preview live on the right, and press Ctrl+S to write straight back to the original file. Drafts are kept automatically.
Export a single HTML file with styles and images inlined, or a PDF with your choice of paper size, margins and page breaks.
