Writing and content decision
Ulysses
A competent developer can build a useful distraction-free editor with export and blog publishing in about a week, but reproducing Ulysses’ deep Apple integrations, polished native UX, iCloud sync and integrated Apple Intelligence proofreading is not realistic for one person.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Open a focused editor -> write/organize sheets in a library -> export or publish to a blog
What it still won’t have
- Tight Apple platform integrations (Apple Intelligence proofreading)
- Seamless iCloud sync across Apple devices
- Polished macOS/iPad/iPhone native UX and long-term maintenance from vendor
- Automatic App Store updates, family-sharing and volume-licensing infrastructure
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a cross-device writing app using Electron (macOS desktop) or SwiftUI (preferred for Apple-native) + a lightweight Node.js backend for optional syncing: implement a markdown/ulss-like editor with sheet/chunk model, a library view (projects/groups/filters/keywords), exports to PDF/DOCX/EPUB/HTML with a style/template system, publishing adapters for WordPress/Ghost/Medium via their REST APIs, and a grammar/style check integration using an external NLP API. Out of scope: App Store distribution, family-sharing, and a full CloudKit/iCloud sync implementation (provide simple encrypted user-scoped sync via the Node backend instead). Include error handling for network/API failures, input validation, and automated tests for editor rendering, export output, and publishing flows.

- Price verified on pricing page+3
- 3/3 assessment runs agreed+4
- Evidence score67
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
