Prompt

Build a native macOS app called Minimax NotchWrite from scratch in this empty project folder.

It should live in the MacBook notch. Clicking it smoothly expands a small, minimal black panel with orange accents.

Let me paste text and choose Fix Grammar, Humanize, Shorten, or Change Tone. Show the rewritten result with Copy, Retry, and an Original/Result comparison.

Use MiniMax's API. Let me enter my subscription API key, store it securely in Keychain.
