Changes confirmed high confidence

Anthropic expands Claude Cowork to web and mobile with remote, continue-while-away sessions

The July 9–13 wave takes Anthropic's knowledge-work agent beyond desktop — still research-preview tier, pitched against Microsoft Copilot Cowork and OpenAI's agent mode.

Anthropic expanded Claude Cowork — its agent for enterprise knowledge work — from desktop to web and mobile in a wave spanning July 9–13, 2026, adding remote session handoff so tasks continue while users are away. Per changelog summaries of the release, Cowork sessions are "now accessible from claude.ai and the Claude mobile apps," with tasks continuing while users are away, as reflected on the Claude Cowork page and Anthropic's news feed.

Context

Cowork is Anthropic's answer to the agentic knowledge-work category: long-running tasks executed against files, apps and browsers rather than single-turn chat. The desktop-first launch limited it to a single machine; web and mobile access with session persistence is what makes an always-on agent practical — work continues server-side while the user is offline, and the user checks in from any device.

What changed

Why it matters

The expansion moves Cowork from a power-user desktop tool toward an enterprise surface, directly against Microsoft Copilot's Cowork scenarios and OpenAI's agent mode. The competitive frame is no longer model quality alone but session persistence: which vendor's agent can hold a multi-hour task state reliably across devices. For IT teams, continue-while-away execution also sharpens governance questions — an agent working unattended needs the spend limits, entitlements and audit logging Anthropic shipped for Claude Enterprise on July 2.

Details

The wave ran July 9–13 across Anthropic's product channels, with capability confirmation via Anthropic's own pages. Positioning against Microsoft and OpenAI equivalents is explicit in Anthropic's framing, per coverage of the release.

Limitations and caveats

Cowork remains preview-tier: availability, task-duration limits and enterprise-plan gating were not fully specified in the materials reviewed, and "sessions continue while users are away" describes vendor-stated behavior that enterprises should validate in pilot before delegating unsupervised work. GA timing has not been announced.
