What they did
After moving from the Codex app to T3 Code, a developer missed ChatGPT's dictation, so he built GPT Voice: press a shortcut, speak, and the transcription is pasted wherever you're typing in any Mac app.
Result (as claimed)
Released free and open source.
Tools they used
Cost: OpenAI Codex: free plan, paid from $8/mo. Checked 2026-10-14.
Set it up
Write a one-page brief
Describe the app in plain words: who it is for, the 3 core screens or actions, and what "done" looks like.
Start the project with your agent
Open T3 Code and paste the brief. Ask it to propose a stack and a file plan before writing code.
Build one slice at a time
Ship the smallest working flow first, run it, then add features one by one. Commit after each working step.
Test it like a user
Click through on desktop and phone. Ask the agent to add basic tests and fix anything that breaks.
Check security and ship
Keep keys in environment variables, check auth and database rules, then deploy and share the link.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Related use cases
Build and ship a native Swift menu bar app solo with Claude Code and Codex
A solo developer builds FavTray, a native Swift and SwiftUI menu bar app, with Claude Code and Codex. He shipped versions 2.1 and 2.2 on consecutive days and still runs and tests every change himself.
Design a device UI with ChatGPT sprites and port it to LVGL with agents
A hardware builder made the screens and sprites for his Capy device in ChatGPT, exported a transparent sprite sheet so nothing had to be cut out by hand, and had Codex and Claude Code slice the art and port the UI to the LVGL embedded graphics library.
Let Claude Code control your Mac in the background with Codex's computer use
A developer exposed Codex's computer-use ability to other agents and plugged it into Claude Code, which has no built-in way to drive a Mac from the CLI. Claude Code can now click and type in Mac apps in the background while you keep working.
Turn a spare Mac into throwaway macOS desktops for your agents
A developer built desktop-plane, an open-source tool that turns a spare Mac into fresh macOS virtual machines agents can use. Each VM starts in about 6 seconds and is deleted after use, and it works with Claude Code, Codex, Hermes or any agent.
