Build your own assistive-tech Mac app with Claude Code

Try it yourself

What you get

A working, custom native Mac app that solves your own accessibility problem.

Tools

• Claude Code (Pro plan)
• GSD workflow (the author later warned against the version the author linked; see source)

Time / cost: About 8 hours and about $80 of extra usage on a $20/month plan (per author)

Steps

1. Describe the problem and answer the agent's clarifying questions.
2. Work in phases (discuss, plan, execute, verify), keeping the state in markdown files.
3. Build in milestones: settings window and shortcut, basic scrolling, then extras.
4. Test each phase yourself and report issues back.

Copy-ready prompt

I want a small native macOS app that solves this accessibility problem: [describe]. Before writing code, ask me clarifying questions, then write a plan in PLAN.md with milestones. Build one milestone at a time, and after each one tell me exactly how to test it.

Watch out: The author later updated the post to warn against installing the GSD version the author had linked.
