GOOGLE’S 24/7 AI AGENT LANDS ON MAC AND THE RACE TO OWN YOUR DESKTOP IS NOW A THREE-WAY WAR Gemini Spark, Google’s always-on AI agent that was announced at Google I/O in May, is now available on Mac and the desktop AI war just got real. Spark can sort your files, watch a topic in real time and alert you when something changes, connect to Google Tasks and Keep, and initiate tasks that span your computer and Google’s cloud. It also supports Model Context Protocol, which means developers can wire it into practically any tool with an MCP connector. Google is going after a specific gap: the persistent desktop assistant that does not wait to be asked. Spark is not a chatbot you open when you need it. It is something running in the background, tracking what you told it to track and acting when conditions change. The direct competitors are Claude Desktop from Anthropic, which has been building its own agentic capabilities for months, and Microsoft’s Copilot, which is baked into Windows. Google has one major advantage in this fight: it already owns the applications most professionals actually use. Gmail, Calendar, Drive, Docs. Getting Spark to see and act on those things is not an integration project for Google. It is a native capability. Apple is also reportedly building its own always-on agent layer into macOS. The fight to live on your desktop and run your digital life is only getting started and the players are all in.
