Anthropic launched Claude Cowork on mobile and web, beginning in beta for Max subscribers before expanding to additional plans.
Anthropic, the AI developer behind Claude, published usage data from 1.2 million anonymized Cowork sessions sampled May 11-May 31 from more than 600,000 organizations showing business process and operations at 33.4% and content creation at 16.4%, together roughly half of usage while software development accounted for 8.7%.
"Your work goes everywhere with you, and keeps going without you," Anthropic writes in its announcement.
Cowork now syncs sessions across devices, can run scheduled autonomous tasks server-side while users are offline, and surfaces decisions for human review on the user's phone.
Desktop remains the most fully featured surface with local file and browser access, the web client removes install barriers in managed environments, Anthropic unified chat and Cowork on a single home screen, and the company has doubled Cowork usage limits through August 5.
The company frames the dominant use cases as "the work around the work," connective tasks like status updates, slide decks and reconciliations that span roles rather than replace core expertise.
Anthropic last week launched Claude Sonnet 5, which powers Cowork and is priced at $2 per million input tokens through August 31 before rising to $3 per million input tokens.
Two weeks earlier Anthropic released Claude Tag, a Slack-native agent the company says generates 65% of its own product team's code internally.
Security researchers at Armadin reported a Windows sandbox escape against Cowork's desktop VM, which Anthropic said requires prior local code execution; moving task execution server-side on web and mobile removes that specific local VM surface but raises data-handling questions for scheduled background workflows.
CNBC reported Alibaba will ban employees from Anthropic tools from July 10 after Anthropic accused Alibaba of a large distillation attack, and Reuters reported Anthropic signed a $19 billion, 20-year lease with TeraWulf for a Hawesville data center expected to reach 401 megawatts and be fully operational in 2028.
Anthropic notes limits to its analysis: sessions are labeled by task not job title, the sample is rate-capped and underrepresents peak hours, about 5% of sampled sessions were personal use, and the labeling pipeline changed roughly May 11.
