Everywhere is a desktop AI assistant for Windows and macOS that you summon with a keyboard shortcut no matter what you are doing on your computer. When it appears, it can see what is currently on your screen and immediately answer questions about it, summarize it, translate it, or help you rewrite it. The key difference from most AI chat tools is that you do not need to copy text, take a screenshot, or switch applications. You bring the assistant to where your content already is. Practical examples from the README include: you see an error message in a terminal window and ask Everywhere what it means and how to fix it, you are reading a long article in the browser and ask for a short summary, you highlight a foreign word and ask for a translation, you draft a business email and ask for a more formal tone. The assistant reads the context from your screen using accessibility APIs and UI automation, not just a screenshot, which gives it a more precise understanding of what is visible. The application connects to a range of AI providers, including OpenAI, Anthropic Claude, Google Gemini, DeepSeek, and local models via Ollama. You can bring your own API key for any of these or use the project's own cloud service. Beyond answering questions, it has an agent mode where it can browse the web, read and write files, run terminal commands, and call external tools via the MCP (Model Context Protocol) standard. The app is built in C# using the .NET 10 framework and the Avalonia UI library, which is what allows it to run on both Windows and macOS. A Linux version is in progress. The interface uses a frosted glass visual style and supports Markdown rendering and math formula display in responses. The project is available in over ten languages and is licensed under Apache 2.0.
