lencx/chatgpt ? reverse-engineered prompt

Build me a cross platform desktop app for ChatGPT that works on Mac, Windows, and Linux, with a clean native feeling interface that launches fast and is easy to use every day.

It should feel like a polished wrapper around ChatGPT, with a simple chat view, smooth window controls, a nice app icon, and the usual desktop app basics like remembering state between launches. Keep the design modern and minimal, and make it feel lightweight instead of like a browser tab. If there are any setup details or the latest docs you need, look them up online and follow the current best approach.

I want the whole thing to be ready to run locally and packaged as a real desktop app, with the code organized so it is easy to maintain and extend later.
