Announced alongside other improvements to Anthropic's Claude and Haiku models, the tool is straightforwardly called "Computer Use." It's available exclusively with the company's mid-range 3.5 Sonnet model right now, via the API. Users can give multi-step instructions (Anthropic claims it can go for tens or even hundreds of steps) to accomplish tasks on the user's computer by "looking at a screen, moving a cursor, clicking buttons, and typing text."
