Aside Computer Use lets the Y Combinator browser agent read and control other apps on a Mac or Windows PC, alongside the logged-in websites it already works in. It is for people who hand Aside tasks across email, dashboards, internal tools, and local files, then still need a step completed in desktop software. The company is shipping it now because browser agents stop at the window, and Aside's launch pitch is that most work still happens in the browser, with this release meant to reach the apps around it. You turn Computer Use on in Settings under Agents, name the apps in chat, and watch a live preview, with the option to take over. On macOS, after Accessibility and Screen Recording are allowed, a task can keep operating several apps in the background. On Windows, the agent can find installed apps that are closed, minimized, or opened from the Start menu, including ones that need administrator rights. The feature only runs on the computer in front of you. Tasks in the cloud, or on another device through Remote Control, cannot use it. Aside already signs into sites directly, keeps memory on the device, and autofills credentials without showing them to the model. Co-founder Chanhee Lee had called desktop control the missing piece as the team moved the product from an AI browser toward a personal work assistant that can follow a job through to the end. Computer Use is that step, on both platforms Aside already ships.
