Ulysses vs iA Writer: Which Minimal Writing App Deserves Your Words?

Both Ulysses and iA Writer belong to the “distraction-free writing” category: clean interfaces, Markdown support, and a philosophy that writing software should get out of the way. Both are excellent. Both have devoted users who can’t imagine switching. But they’re designed for different kinds of writers, and choosing between them comes down to how you think about your writing.

Here’s the honest comparison after years of using both.

The Philosophy Difference

iA Writer believes in radical simplicity. One document at a time. Minimal features. The interface is so clean it borders on austere. The app’s opinion: the fewer decisions you make about your tool, the more attention you give to your writing.

Ulysses believes in organized simplicity. A library system, groups, filters, and keywords let you manage an entire writing life within the app. The interface is clean but feature-rich. The app’s opinion: writers need organization alongside focus, and both should be elegant.

This philosophical split defines every difference between them.

Interface and Design

iA Writer: A single pane with your text. That’s essentially it. The toolbar is minimal. The sidebar (when opened) shows files from iCloud Drive or other storage locations, but the default state is just you and your words. The typography is iA’s custom font—Writer Duo for monospace, Writer Quattro for proportional—both designed specifically for readability while writing.

The Focus Mode dims everything except the current sentence or paragraph, which is effective for fighting distraction. The syntax highlighting of Markdown is subtle and tasteful.

Ulysses: A three-pane layout: library/groups on the left, document list in the middle, editor on the right. The editor itself is clean and focused, but the surrounding structure is always available. Ulysses uses its own flavor of Markdown (Markdown XL) with visual formatting that sits between raw Markdown and rich text.

The interface feels like a beautifully designed productivity app. iA Writer feels like a sheet of paper.

Organization

iA Writer: Relies on your file system. Documents are stored as plain text (.txt) or Markdown (.md) files in folders you manage yourself—iCloud Drive, Dropbox, or local storage. The app provides no organizational structure beyond what your folder system offers.

This is deliberately minimal. Your files aren’t locked in an app database. You can open them in any text editor. They’ll survive the app being discontinued. The trade-off: if you have hundreds of documents, managing them through folders alone can get unwieldy.

Ulysses: Has its own library system. Documents are organized into groups (like folders), can be tagged with keywords, and can be filtered and searched across your entire library. The library syncs via iCloud across Mac, iPad, and iPhone.

For writers managing multiple projects—a novel, blog posts, journal entries, freelance articles—Ulysses’s library is genuinely powerful. You can find any document through search, filter by keyword, or browse by group. The organization never feels heavy because the interface is so clean.

The trade-off: Ulysses stores documents in its own database format, not as plain files. Export is easy (to Markdown, plain text, HTML, PDF, DOCX, ePub), but your documents are inside Ulysses’s system, not your file system.

Markdown Support

iA Writer: Standard Markdown and CommonMark. What you type is what you’d type in any Markdown editor. The preview shows rendered formatting. Content blocks let you embed images, CSV tables, and even other text files.

Ulysses: Markdown XL, a proprietary extension. Bold, italic, and headers use standard Markdown syntax, but links, footnotes, annotations, and other elements use Ulysses-specific syntax. This means documents exported from Ulysses need conversion to standard Markdown.

For writers who work across multiple tools or who value plain-text portability, iA Writer’s standard Markdown is a significant advantage. For writers who live entirely within Ulysses, the extended syntax is more capable.

See [INTERNAL: markdown-for-writers] for a general guide to Markdown in writing workflows.

Publishing and Export

iA Writer: Exports to Markdown, HTML, PDF, and DOCX. Integrates with WordPress for direct publishing. The Content Blocks feature can pull in external content for sophisticated assembled documents. Exports are clean and predictable.

Ulysses: Exports to Markdown, HTML, PDF, DOCX, ePub, and more. Publishing directly to WordPress, Ghost, Medium, and Micro.blog is built in. The export engine is more sophisticated—you can customize styles, headers, and formatting for each export format.

Winner: Ulysses for publishing breadth and customization. iA Writer for plain-text fidelity and simplicity.

Platform Availability

iA Writer: Mac, iOS, iPadOS, Windows, and Android. The cross-platform availability is a major advantage. You can write on Mac at home and continue on a Windows machine at work or an Android phone on the bus.

Ulysses: Mac, iOS, and iPadOS only. No Windows. No Android. If you’re not fully in the Apple ecosystem, Ulysses isn’t an option.

Winner: iA Writer, decisively, for platform coverage.

Pricing

iA Writer: One-time purchase, roughly $50 per platform (Mac, Windows, iOS). You buy it once and own it. Check the App Store or iA’s website for current pricing.

Ulysses: Subscription, roughly $6/month or $50/year. Includes Mac, iPhone, and iPad with a single subscription. If you stop paying, you can still access your documents but cannot edit them within Ulysses. Check the App Store for current pricing.

This is a meaningful difference. iA Writer’s one-time price means you pay once and use it forever. Ulysses’s subscription means ongoing cost but also ongoing development and updates.

For writers on a budget: iA Writer. For writers who don’t mind subscriptions and want continuous feature updates: either works financially.

Writing Experience

Here’s where it gets subjective, and where the choice really lives:

iA Writer provides the purest writing experience I’ve found in any app. The custom fonts are gorgeous. The Focus Mode is genuinely effective. The lack of organizational overhead means your attention goes to words, not management. When I sit down to write a single piece—an essay, an article, a chapter—iA Writer is where I open first.

Ulysses provides the best managed writing experience. When I’m juggling a novel project, weekly blog posts, and freelance articles, Ulysses keeps everything accessible and organized. The writing experience is excellent—not quite as stripped-down as iA Writer, but clean and focused with powerful organization one click away.

Who Should Choose Which

Choose iA Writer if:

You want radical simplicity
You write on both Apple and non-Apple devices
You prefer one-time purchases over subscriptions
You value plain-text file storage
You write primarily single documents (articles, essays, stories)
You have an existing file organization system you’re happy with

Choose Ulysses if:

You’re fully in the Apple ecosystem
You manage many writing projects simultaneously
You publish to multiple platforms (WordPress, Medium, Ghost)
You want your writing tool to also be your writing organizer
You’re comfortable with subscription pricing
You write across many formats and need them all in one library

Choose Scrivener instead if:

You’re writing novels or book-length projects that need outlining, research management, and structural tools. Scrivener is in a different category from both—see [INTERNAL: scrivener-deep-dive].

My Recommendation

If you’re genuinely undecided, start with iA Writer. The one-time purchase means you’re not locked into a subscription, the cross-platform support keeps your options open, and the simplicity means you’ll be writing within minutes of installation. If you later find you need more organizational power, try Ulysses’s free trial.

Both apps represent the best of minimal writing software. You won’t be disappointed with either. The question isn’t which is better—it’s which matches how your brain works.
