iA Writer
A focused Markdown editor that knows what you actually wrote
About iA Writer
iA Writer strips writing down to a cursor and beautiful typography, with syntax highlighting and focus mode as its only real concessions to features.
The 2026 conversation is all about Authorship, which tracks what you typed versus what you pasted from an AI — surprisingly clarifying if you draft with ChatGPT but want to know how much of the result is yours.
It's $49.99 one-time on the Mac. Among minimal Markdown editors it's the one I keep coming back to; the discipline it imposes is the product.
