What 1.2 Million Claude Cowork Sessions Reveal About How People Really Use AI

Ask most people what AI gets used for in the workplace and “writing code” is usually the first answer. New usage data shared by Anthropic suggests the reality looks very different.

The company analyzed a sample of 1.2 million anonymized Claude Cowork sessions and found that more than 90% of them fell outside software development entirely. The bulk of what people delegate to the AI assistant isn’t engineering — it’s everyday knowledge work.

The Biggest Category: “The Work Around the Work”

The largest share of sessions belongs to a category Anthropic describes as “the work around the work.” These are the tasks that surround a person’s actual job: drafting a status update, building a slide deck, or condensing a pile of research into a single report.

What makes this category interesting is its in-between status. As Anthropic puts it, these tasks move projects forward and keep businesses running — yet they are rarely anyone’s core responsibility. Nobody was hired to write status updates. But someone still has to write them, and until now, that someone was you.

Where the Recovered Time Goes

The more telling part of the data isn’t just what people hand off — it’s what they do with the hours they get back.

According to Anthropic, people who delegate this supporting work to Claude Cowork are redirecting the recovered time toward the parts of their job that genuinely need human judgment.

The example Anthropic gives is a hiring manager. Instead of spending the day on interview scheduling and writing up feedback summaries, the manager hands those tasks to Cowork — and uses the freed-up time for the thing that actually determines hiring quality: real conversations with candidates.

The scheduling still happens. The summaries still get written. But the human in the loop is now spending their attention where a human adds the most value.

Why This Data Matters

Two takeaways stand out from Anthropic’s numbers:

1. AI at work is not a developer story. With over 90% of the analyzed Cowork sessions falling outside software development, the picture that emerges is of AI as a general knowledge-work tool — used for reports, decks, and updates — rather than a coding assistant that happens to do other things on the side.

2. Delegation is reshaping how time is spent, not just how tasks get done. The pattern in the data isn’t people doing the same job faster. It’s people offloading the supporting tasks entirely and reallocating that time to judgment-heavy work — the conversations, decisions, and thinking that can’t be delegated.

FAQ

What did Anthropic’s Claude Cowork analysis find? An analysis of 1.2 million anonymized Claude Cowork sessions found that more than 90% fell outside software development, with most usage being everyday knowledge work.

What is “the work around the work”? It’s Anthropic’s term for the tasks surrounding a person’s core job — drafting status updates, building slide decks, condensing research into reports. They keep businesses running but are rarely anyone’s main responsibility.

What do people do with the time AI saves them? Based on the usage patterns Anthropic describes, people spend the recovered time on the parts of their job that require human judgment — like a hiring manager trading scheduling admin for more conversations with candidates.
