1.2 million Cowork sessions reveal how people actually use it!

Hey everyone, it's Shiichan! Anthropic just shared some real numbers on how people actually use Claude Cowork!

What was announced?

On the Claude Blog, Anthropic published a report analyzing how Claude Cowork is actually being used, published the same day as the mobile/web launch news. Cowork tends to sound like a coding agent, but this report shows, with real numbers, what kinds of everyday work it's actually being used for.

Why it matters

Since Cowork is one of Claude's agentic features, it's easy to assume it's mainly a tool for engineers to get code written. But the actual usage data paints a pretty different picture. Knowing what kinds of work it's used for, and how much, makes it a lot easier to picture how you might use it yourself.

What changes

First, the methodology: Anthropic analyzed 1.2 million anonymized, aggregated Cowork sessions from May 11-31, 2026, spanning more than 600,000 organizations, sorting them into a 20-category taxonomy with an automated classification system. It's built with privacy in mind; no individual session was reviewed by a human, only aggregate statistics were examined. Sampling used rate-capping (a fixed maximum number of sessions per hour), not percentage-based sampling.

Here's the breakdown of the top categories:

• Business process and operations: 33.4%
• Content creation and copywriting: 16.4%
• Software development: 8.7%
• DevOps and infrastructure: 7%
• Research and intelligence: 6.4%
• Data analysis and business intelligence: 5.8%
• Document processing and extraction: 4.1%
• Sales and revenue operations: 4%
• Personal assistance: 3.8%
• Education: 2.4%
• Meeting intelligence: 1.8%
• Legal and compliance work: 1.3%
• Customer support: 0.8%

The top two categories, business operations and content creation, together account for roughly half of all usage. Software development sits at just 8.7%, a smaller slice than you might expect.

Dive Deep

Examples of "business process and operations" work include pulling scattered updates into a single report, building onboarding checklists, and reconciling spreadsheets. "Content creation" mostly covers drafting, building slide decks, writing posts, and putting together proposals.

An interesting contrast: developers use Claude Code mostly for core coding work, but Cowork skews toward "connective work," reading and responding to communications, gathering and organizing information, even though it's an agentic product adjacent to AI coding tools. It's a notably non-technical usage pattern for an agent product.

The report gives concrete examples too: a lawyer might delegate document formatting to Cowork so they can focus on legal judgment, or a hiring manager might use it to synthesize interview feedback while spending their own time on candidate conversations.

The conclusion is simple: knowledge workers mostly use Cowork to gather and structure information, freeing up time for the higher-expertise work that's specific to their actual role.

Wrap-up

• Anthropic published a report analyzing real Cowork usage: 1.2 million sessions across 600,000+ organizations.
• The top category is business process and operations at 33.4%, followed by content creation at 16.4%, together about half of all usage.
• Software development is only 8.7%; Cowork skews toward non-coding "connective work."
• Concrete examples span non-engineering roles too, like lawyers and hiring managers.
• The goal: let Cowork handle gathering and organizing information, so people can spend more time on the work only they can do.

If you thought Cowork was "just for coding," or you're curious how it might fit into your own work, this report is worth a look!
