Sylinko/Everywhere — reverse-engineered prompt

Build me a polished desktop AI assistant called Everywhere that can pop up with a global shortcut and understand what I’m looking at on screen without me having to take screenshots or copy text around. I want it to feel like a floating helper beside whatever app I’m using, with a clean modern frosted glass style UI, markdown support, and easy text selection actions.

The main experience should be that I can open it over an error message, article, email draft, or foreign language text and ask things like explain this, summarize it, translate it, rewrite it more professionally, or check if it’s true. It should use the current app context and selected text when possible. Let me choose between several AI providers, including cloud models and local ones, and support custom API endpoints too.

It should also be able to do useful agent tasks like web browsing, reading local files, running terminal scripts, and using MCP tools. Please make it work well on Windows and macOS first, with room for Linux later. Check the current docs online if needed.
