Markdown, transformed.
MarkdownBláthy is a desktop Markdown editor with live preview and on-demand PDF export. The preview and the PDF are produced by the same Typst compilation pipeline — true WYSIWYG. The name commemorates Ottó Titusz Bláthy who among his other inventions became the co-inventor of the efficient alternating current transformer.
- Split-screen editing — Markdown on the left, live preview on the right.
- Pixel-identical preview — the preview is rendered by the same Typst compiler that produces the PDF, so what you see is what you get.
- Export to PDF — one click, system save dialog, opens in your default PDF viewer.
- Multiple Markdown flavors — CommonMark, GFM (GitHub Flavored Markdown), or Custom (footnotes, math, task lists).
- LaTeX-style math — inline and display math use familiar TeX/LaTeX notation (fractions, roots, matrices, common macros); Typst renders the preview and PDF.
- Custom templates — supply your own
.typtemplate to restyle everything (colors, fonts, layout) while keeping the editing experience. - Heading IDs — every heading gets an automatic anchor link; override with
{#custom-id}syntax. - Footnotes — inline references with note blocks at the bottom; clickable markers in the preview.
- Settings persist — your flavor, paper size, margins, and template are saved between sessions.

The full implementation specification lives in SPEC.md.
- Legacy-codepage filenames — on Linux systems using a non-UTF-8 locale (e.g. latin-2), a file's name is echoed over IPC as a lossy UTF-8 string. Contents load and saves still write to the correct file, but Save-after-Open may create a new file with a mangled name instead of overwriting. UTF-8-locale Linux, macOS and Windows are unaffected. Details in SPEC.md.
