nextai-translator/nextai-translator ? reverse-engineered prompt

Build me a translation app that works both as a browser extension and as a desktop app for Windows, Mac, and Linux.

I want to be able to select text anywhere and instantly get a popup with translation, plus a few extra AI powered options like polishing writing and summarizing text. It should support streaming results, one click copy, text to speech, and screenshot translation too. Please make it easy to set up my own API key, and support common AI providers like OpenAI, Azure OpenAI, and other compatible services if possible.

I’d also like a simple vocabulary book feature so I can save words I look up and review them later, with a way to generate memory aids from saved words. Keep the UI clean and fast, and make the extension and desktop version feel like the same product. If you need to check any current browser or app docs while building it, go ahead and look them up.
