Focused editor — Not much to click. Plenty to write ?
A text-first editing surface for sustained writing. No chrome, no distractions, no clever tricks.
Yes, it’s “just” an editor. That’s the point.
Markdown,
now with a sense of direction.
Sommaire is a focused macOS editor for long-form Markdown documents.
It’s built for texts that have chapters, sections, and opinions about hierarchy.
The interface stays deliberately minimal, keeping the text front and center.
A live, self-updating Table of Contents sits quietly in the sidebar, making sure you always know where you are and how you got there.
When the draft is done (or done enough), Sommaire steps aside.
This is where layout tools take over.
Features
Sommaire is minimal by design: write continuously, keep structure visible, and move through chapters without losing your place—or your patience.
Syntax highlighting — So you don’t have to squint
Sommaire highlights Markdown in place, without turning your document into a preview or a performance. Syntax is colour-coded and gently indented so structure reads instantly, while the words keep their authority.
Headings, lists, quotes, emphasis, links, and code blocks are distinguished just enough to be helpful—without forcing you to hunt for #, *, or stray backticks.
Nothing collapses. Nothing hides. Nothing jumps out to surprise you. You always edit the source text. You just don’t have to mentally parse it while trying to think.
Live Table of Contents — Always know where you stand
A self-updating outline in the sidebar.
One click to jump anywhere, zero scrolling archaeology. Built for books, reports, technical documentation, chapters, and those notes that started small and got out of hand.
Writing statistics — For those who like to know
Live word counts, character counts, readability indicators, and other numbers that quietly judge you.
You can ignore them. They won’t take it personally.
IDML export — For layout work
Sommaire treats IDML export as a core part of the workflow, not an afterthought.
Structured Markdown is handed off cleanly to professional layout tools.
- Headings become semantic paragraph styles
- Paragraphs, links, emphasis, and quotes are preserved
- No visual decisions baked into the text
- Ready for InDesign or Affinity, without cleanup
Typography, pagination, and strong opinions about margins belong in layout tools.
Sommaire knows when to get out of the way.
PDF, HTML and print — For everyone else
Of course, Sommaire also exports to PDF and HTML, and can print directly. These formats follow your document’s structure and can include a generated Table of Contents, for when you want the outline to travel with the text.
