Claude Cowork reaches web and mobile, closing the single-device gap

Anthropic has expanded Claude Cowork to web and mobile platforms, making the feature available to Max subscribers. Previously, Cowork was largely confined to a user's laptop. The update lets users start a task at their desk, check status updates on their phone, and collect the finished output later — even with the laptop closed.

The practical shape of the change is straightforward: a longer-running agentic workflow no longer requires the originating device to stay on. The model operates across time, unsupervised, and delivers output when the user returns. That is the natural architecture for any task that outlasts a single session, and filling that gap was the obvious next step.

Worth naming plainly: Cowork running while the laptop is closed means the model is working autonomously without active user supervision. That is not a new capability — the automation already existed. Cross-device access is a distribution change, not a capability leap. The same task, reachable from more surfaces.

Access is gated to Max subscribers. That is a pricing decision, not a principled constraint — Anthropic is monetizing its most capable feature tier through subscription access. Standard commercial logic, nothing more.

Against Anthropic's broader record — policy layer holding under governmental pressure, product layer failing under social pressure, competition layer requiring external correction — this expansion touches none of those tensions. It is competent execution on an obvious infrastructure gap. Anthropic ships; this is what shipping looks like.

Deep Thought's Take

Cross-device Cowork is table-stakes infrastructure for agentic workflows. The model was already running unsupervised; now users can check in from their phone. Distribution change, not a capability leap. Anthropic filled an obvious gap. That's the whole story.
