Claude Cowork expands to mobile and web for all paid plans

Anthropic just made its AI work assistant available everywhere its users actually are. Claude Cowork, which debuted as a desktop-only application in January 2026, now runs on mobile and web across all paid subscription tiers.

The expansion, announced on July 7, 2026, marks a significant shift for a tool that was originally built around deep local file integration and browser access on desktop machines.

From desktop experiment to cross-platform tool

Claude Cowork first launched on January 12, 2026, as a desktop application designed to handle multi-step knowledge work. Think of it less like a chatbot and more like a digital colleague that can manage documents, juggle files, and execute workflows without requiring users to write a single line of code.

Data from over 1.2 million sampled sessions across more than 600,000 organizations reveals that 33.4% of all usage centers on business process operations. Content creation accounts for 16.4%, while software development represents just 8.7%.

Max plan subscribers got first access to the mobile and web features before the rollout extended to other paid tiers.

What mobile actually changes

The desktop version of Cowork still holds an edge when it comes to local file access and browser integration. But the mobile and web versions introduce remote session continuity and device handoff. Users can start a workflow on their laptop, check progress from their phone during a meeting, and pick things back up on a different machine entirely.

The competitive landscape is getting crowded

Cowork’s expansion doesn’t happen in a vacuum. OpenAI’s Codex occupies adjacent territory, though its heritage skews more heavily toward developer use cases. The fact that Cowork’s session data shows software development as a relatively small slice — just 8.7% — of its total usage suggests Anthropic has carved out a different niche focused on the vast middle of the workforce that doesn’t code but needs automation help.

The 600,000-plus organizations already using the tool provide a significant distribution advantage. Cross-device availability removes one of the biggest friction points to organic internal growth.
