FrankenMarkdown

Write Markdown, inspect the document as a system, and publish a finished file without sending the text to a server.

FrankenMarkdown keeps the source and rendered document together. The editor provides live syntax highlighting, line numbers, an outline, and an automatically updated preview. On iPad and Mac, source and output can remain visible side by side; iPhone uses focused lanes sized for the smaller display.

Document Lab adds the tools needed for longer work: word and reading statistics, structure and accessibility checks, semantic comparison between revisions, polished document templates, and publishing controls. Multi-chapter projects can produce a continuous PDF or a self-contained site package.

Export the current document as PDF or self-contained HTML. The bundled Rust rendering engine handles typography, tables, code, mathematical notation, and document structure locally.

No account, advertising, tracking, or cloud processing is required. Your text stays on the device unless you choose to share an exported file.
