Can I vibecode Ulysses?
// one session, and a personal version you can actually use
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.

The prompt
One session with a coding agent and your version runs.
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. Prompt generated from the data on this page, not reviewed by hand yet. In English on purpose — it is the language coding agents work best in.
What you lose
- 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
Why people still pay
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.
