TheHolyOneZ/GrammarFixer — reverse-engineered prompt

Build me a simple Windows desktop app called Grammar Fixer that sits in the background and fixes writing anywhere with a global hotkey, like Ctrl Alt T by default. When I highlight text in any app and press the hotkey, it should grab the text, send it to Google Gemini, and either replace the original text, copy the corrected version to the clipboard, append or prepend it, or show it in a popup.

I want it to feel easy and polished, with a compact view and an advanced settings view. Let me choose correction speed, pick a writing style like friendly or professional, create custom personas, detect the input language, optionally translate to another language, and choose the Gemini model. It should save my API key, support minimize to tray, optional startup with Windows, notifications, sounds, basic fix history, and token or cost tracking. A small debug window for troubleshooting would be great too.

Please make it ready to run on Windows, and look up current Gemini docs online if you need to.
