What iA Writer does on Mac
iA Writer is a minimalist Markdown writing app for macOS from Information Architects that removes formatting clutter so you can focus on sentences, with plain-text editing and a clean preview when you need structure.
Since 2010, iA Writer has targeted journalists, authors, and professionals who want a calm writing surface instead of a full word processor. You write in Markdown, use Focus Mode to dim everything except the current sentence or paragraph, and export to HTML, PDF, Word, or publishing platforms when the draft is ready.
Core writing tools
- Focus Mode for sentence- or paragraph-level concentration
- Syntax highlighting for Markdown structure as you type
- Style Check to flag weak verbs, filler adjectives, and repetitive phrasing
- Content blocks and wikilinks for embedding files and linking notes
- Library access to local folders and cloud locations without leaving the app
- Export to HTML, PDF, Microsoft Word, WordPress, and Medium templates
Authorship and AI transparency
From the 7.x line onward, iA Writer tracks who wrote each passage. Pasted AI text appears in distinctive gradient coloring; human contributors show in subtler tones you can assign in settings. Reference material stays dimmed so you can see edits to contracts, drafts, or mixed-source documents without sending content to cloud AI services.
Typical Mac workflow
Open a plain-text draft, enable Focus Mode for a long-form session, run Style Check before export, and sync files through iCloud or your preferred cloud folder. Bloggers draft in Markdown and publish via custom templates; developers keep notes with wikilinks between project files.
Version 8.0
Version 8.0, released June 2026, is a major visual and navigation update. The interface adopts Apple Liquid Glass styling on macOS 26 and later, with an app icon that follows system light, dark, and clear appearance settings. Quick Search now merges document outline, in-file find, and library search: type a few letters to jump to headings, filenames, or text matches. A new Command Palette centralizes formatting, export, and Authorship actions behind Shift-Command-P on Mac. The library gains a compact layout that can hide dates and excerpts, and favorite files show a star for quicker browsing.
Licensing and requirements
iA Writer for Mac costs about $49.99 as a one-time purchase on the Mac App Store or through iA Account direct sales, with a one-week free trial on the vendor site. macOS 10.15 is the listed minimum; Liquid Glass and the refreshed interface target macOS 26 Tahoe. iPhone and iPad licenses are separate purchases. Diagnostics and usage data may be collected but are not linked to your identity per App Store privacy labels.
