Supports headings, nested lists, task lists, quotes, tables, code blocks, links, images, emphasis, strikethrough, reference links, and footnotes. A contents list is built from the document's headings.
The file is read on your device. Remote images load from their original hosts; web links open in a new tab so your document stays open. Raw HTML is displayed as text. Relative image and file paths cannot be resolved from a single chosen file.
No file-size limit. After a reference-definition pass, completed blocks appear from top to bottom as a background worker parses them. Very large documents still use browser memory and take time to lay out. You can cancel or open another file.
Use a UTF-8 Markdown or text file. This is a documented Markdown subset, not a complete implementation of every Markdown dialect. There is no math typesetting, diagram engine, or syntax-highlighting library.
