Saguinus
A clean, document-shaped markdown editor.
Write markdown the way it's meant to feel — a continuous page with no interrupting breaks, page guides that show where your document will split on export, live formatting as you type, and a plain-text file underneath that stays clean no matter how much you copy, paste, and edit.

Page guides, not page breaks
Write in one continuous flow with no interruptions — subtle page guides show exactly where pages will fall, so what you see lines up with what you get when you export to PDF.
Live rich rendering
Headings, bold, italics, strikethrough, links, and images render as you type, while the file underneath stays plain markdown.
Math with KaTeX
Write inline and block math using familiar LaTeX syntax, with editable source and dedicated toolbar buttons.
Tables & task lists
Build tables and checkbox task lists that render cleanly and round-trip back to markdown without losing structure.
Code blocks
Syntax-highlighted code blocks for sharing snippets, configs, and examples alongside your writing.
Built-in markdown guide
A quick-reference "Markdown Guide" panel covers every supported construct, right inside the app — handy for newcomers.
