Cowork came as a new way of working that generates artifacts and solves multistep problems, and users assign multistep tasks to it.

Judge as of 2026-06-02. True: by that date, a product or feature called Cowork (e.g. Microsoft's Copilot Cowork) had been released or announced as available, and official product material or independent reviews describe it as (a) producing artifacts such as documents, spreadsheets or presentations, (b) working through multistep tasks, and (c) taking tasks that users assign or delegate to it. Mostly true: Cowork existed as described, but a minor detail is off. For example, at that date it was only in preview or early access, or one of these capabilities is described a little differently, while all three still broadly hold. Mixed: Cowork existed, but only roughly half of these elements are supported. For example, it produces artifacts but does not take on assigned multistep tasks. Mostly false: a product called Cowork existed, but by that date it was not a real offering of the kind described, or it does mostly something else. False: no product called Cowork existed by 2026-06-02, or the evidence shows its function is unrelated to what the claim says.

   “We recently introduced Copilot Cowork through the Frontier program to move beyond chat and into execution—helping you delegate real tasks and have them completed for you.”

Microsoft's official Copilot blog posts, dated before 2026-06-02, describe Copilot Cowork as taking work that users delegate or hand off (E1, E2, E4), turning a request into a plan (E2), and producing deliverables such as a briefing document, supporting analysis and a client-ready deck (E3). Together these support all three elements the criteria require. However, E4 says Cowork was introduced through the Frontier program, which suggests early access rather than general availability. The criteria count that as a minor deviation. All the evidence is Microsoft's own product material, which the criteria accept as a source.
