> Anthropic brought Claude Cowork to web and mobile—Max beta first, then broader paid plans. Cloud sessions continue when the laptop closes; phone prompts when a decision is needed. Agentic products stick only if kickoff and oversight are portable.

Agentic products fail in the real world when they **tie users to a single machine**. Mobile + web Cowork is Anthropic admitting that multi-hour agents only stick if oversight and kickoff are **portable**. Paired with OpenAI’s same-week Work/desktop merge, July’s story is less “which model is smartest” and more **who owns the cross-device agent shell**.

**Anthropic** on **July 7, 2026** said **Claude Cowork** is expanding from the **desktop app** to **web and mobile** (iOS/Android). Rollout is a **beta**, starting with **Max** subscribers and expected to reach other paid plans over following weeks. Cowork can run **remote/cloud sessions** so work continues when no device is online, sync files across surfaces, and **notify on phone** when the agent needs a human decision—turning long-running knowledge-work agents into something you can start at a desk and finish on the train.

## What shipped

Grounded in Anthropic’s **Cowork web/mobile** blog post and same-day press (The Verge, 9to5Mac, MacRumors, PYMNTS):

- **Surfaces**: Desktop + **web** + **mobile apps** as one Cowork home for chats, projects, artifacts, and synced files.
- **Access**: Beta first for **Max**; other plans “in the coming weeks.”
- **Session model**: Hand Claude a task at the desk; **background cloud execution** when the laptop closes; **mobile** for monitoring and approvals.
- **Product lineage**: Cowork began as **Anthropic Labs** research preview (January 2026), GA for paid desktop users in **April 2026**, and is Anthropic’s “Claude Code for the rest of work” pitch—folders, connectors, multi-step office tasks.

Later week coverage framed the mobile/web push next to **OpenAI’s July 9 ChatGPT Work** launch as a **category race** for agentic knowledge work. The primary ship date for Cowork’s mobile/web availability remains **July 7**.

## Limits

- Max-first beta; other paid plans follow over weeks—not day-one universal.
- Cloud session reliability and file-sync edge cases are product claims, not independent uptime data.
- “Answer to ChatGPT Work” is same-week category framing; Work shipped two days later.
