Gemini Spark, Google's 24/7 agentic assistant, is now available on Mac (beta, US-only, Google AI Ultra subscribers), where it can work directly with files on the computer - sorting and organising them, or turning a folder of invoices into a budgeting worksheet in Google Workspace. The update adds long-requested Google Tasks and Keep integrations plus third-party hooks into Canva, Dropbox, Instacart, OpenTable, and Zillow Rentals, real-time tracking of topics like stocks and breaking news, and - notably for builders - custom MCP support for wiring in your own apps. It puts Spark in direct competition with Claude Desktop, Microsoft Copilot, and OpenClaw for the desktop, where the real productivity (and governance) questions live.
