Leaf Viewer, for documents worth reading
A read-only Windows document reader that typesets Markdown, LaTeX, notebooks, diagrams, source code, data files, subtitles, and other text formats.
Field notes
The reader organizes rendered material around the document rather than the file extension: headings become a contents rail, numbered equations become anchors, and diagrams, tables, diffs, subtitles, and source code receive format-specific treatment. The homepage lists 177 extensions, including notebooks, Graphviz files, email messages, cue sheets, CP437 artwork, and 60 source grammars. It also states that files remain read-only, Ctrl+U reveals their underlying text, and the engine makes no network requests.
