Sylinko/Everywhere

On-screen aware AI assistant for your desktop. Uses current app context, multiple LLMs, and MCP tools to help you act across apps.

📌 What is Everywhere?

Everywhere is a cross‑platform desktop AI assistant built with .NET 10 and Avalonia UI. It lets you invoke a large‑language‑model (LLM) instantly on‑screen via a global hot‑key, so you can ask questions or run commands without leaving the application you’re using. The app captures the current context (selected text, window title, UI elements, etc.) through accessibility and UI‑automation APIs and sends it to a chosen LLM (OpenAI, Anthropic, Gemini, DeepSeek, Moonshot, MiniMax, Ollama, or a custom endpoint). The response is shown in a modern frosted‑glass window that supports markdown, math, and rich formatting.
