Can AI replace Ulysses?

The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Ulysses, write in a focused Markdown library, organize sheets, set goals, and export polished documents. The hard boundary is native apple polish, icloud sync, mobile apps, and publishing integrations, plus polish, integrations, and proprietary language models.

PlanMonthlyBilled yearlyWhat you get
Monthly$5.99—All Macs, iPads and iPhones on the subscriber's Apple Account
Yearly—$3.33/moAll Macs, iPads and iPhones; Apple Family Sharing with up to 5 other family members
Student—$1.83/moAll Macs, iPads and iPhones for 6 months; no Family Sharing
Business / Volume Licensing——Custom seat count for organizations

Hidden costs: US prices can differ by App Store region; student pricing excludes Family Sharing, and business volume pricing is quote-only.

02Could AI build it for you?

The core job: Write in a focused local Markdown library, organize sheets, set goals, apply editing passes with a visible diff, and export polished documents without uploading them.

What a working version needs:

  • macOS, Windows, or Linux
  • local files
  • optional OpenAI or Anthropic API key for semantic rewrites

Editorial comparison targets the Personal plan and a personal local editor DIY substitute. Recheck price before merge.

03What you'd give up

  • native Apple polish, iCloud sync, mobile apps, and publishing integrations
  • cross-device sync
  • large proprietary style models
  • browser and office-suite extensions
  • team style guides

People still pay for Ulysses because the paid tool is already present everywhere they write and its suggestions have been tuned across millions of documents. The recurring cost buys model quality, extension compatibility, dictionaries, releases, and sync, not just the visible interface.

A local-first writing library with blocks, links, huge documents, and real exports; less monastic than Ulysses, much harder to lose.

A serious Markdown desk with folders, writing targets, citations, and export machinery that occasionally admits Pandoc is under the hood.

05The build prompt

Paste this into an AI coding tool (such as Claude, ChatGPT, Lovable or Replit) to build your own version.

prompt.txt
Build a personal replacement for Ulysses in an empty repository.
Use Tauri 2, React, TypeScript, SQLite, and a small Rust filesystem layer; do not offer alternative stacks.
The core loop is: write in a focused local Markdown library, organize sheets, set goals, apply editing passes with a visible diff, and export polished documents without uploading them.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Create a three-pane editor with source text, suggestion list, and accepted-result preview.
Implement deterministic checks for repeated words, sentence length, passive constructions, and typography.
Add an optional API-backed rewrite action that sends only the selected passage.
Show every change as an accept-or-reject diff and support undo.
Import and export .txt and .md while preserving headings and lists.
Persist user rules, ignored terms, and recent documents in SQLite.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Deliberately leave out a browser extension.
Deliberately leave out Office or Google Docs plugins.
Deliberately leave out collaborative editing and cloud sync.
Finish by running the tests and listing the exact commands used.
