Compositor / the engine behind everything here
Compositor is the typesetting engine behind Typeset Page. Give it Markdown or Word and it’s parsed, typeset, polished and laid out — then handed back as a clean native .docx, a print-ready PDF or a page made for reading. The formatting is a decision, not an accident.
The name / a trade, not a metaphor
In a print shop, the compositor was the tradesperson who took the author’s manuscript and set it in type — the spacing, the hierarchy, the small marks, all decided by hand. That’s the job this engine does with your document: the studio’s taste, applied in seconds instead of days.
The pass / four stages, one engine
Markdown — GitHub tables, task lists, callouts, LaTeX math, Obsidian wikilinks — or a .docx, read into one structured document. Nothing is guessed from the text.
Real typography, not defaults: a considered scale, measured lines, kerning switched on, and native styles in Word so the navigation pane and automatic TOC just work.
The small stuff review cycles are wasted on — curly quotes, real dashes, ellipses, number and currency formats set by the document’s language — fixed, counted, and reported back. Code and anything ambiguous are never touched.
Composed for the destination: a native .docx built on Word’s own styles, a PDF set with Typst, or a reading page that works on any screen, light or dark.
The outputs / one source, three destinations
A real .docx on Word’s own heading styles — navigation pane, automatic TOC and outline view all work, and anyone can edit it after you.
Set with Typst: measured lines, considered spacing, syntax-highlighted code that matches the Word output. Not a print-to-PDF of a Word file.
The page behind Share Markdown — typeset for any screen, with inline comments when you want feedback on it.
Where it runs
On the web, in the Obsidian plugins, behind Share Markdown, or on the other end of the MCP server your AI talks to — pick the way that fits your day. Same engine, same care.
