5 min readClaude Cowork: The Gateway to Agentic AI
Boris, the creator of Claude Code, opens a folder of messy receipts on his desktop. He types a simple request into a new desktop app: "Can you rename the files to match the dates on the receipts?" Within seconds, the app scans the images, identifies dates, renames the files, and asks for clarification on one receipt where the date is unclear. This is Claude Cowork — a new product from Anthropic that puts the power of Claude Code behind a simple graphical interface, no terminal required.
What Makes an Agent Different
Boris is careful to define what "agentic" actually means, because he thinks the term has lost its meaning through overuse. A true agent doesn't just chat back and forth — it takes action. It uses tools on your computer, interacts with files, controls your browser, and generates new documents. Claude Cowork runs on the same Claude Agent SDK that powers Claude Code, but wraps it in a desktop app that anyone can use.

Show Notes
In this episode, I sit down with Boris, the creator of Claude Code and one of the key builders behind Claude Cowork, to unpack what Cowork actually unlocks and how people use it in the real world. He walks through a hands-on demo where Cowork organizes files, extracts receipt data, builds a clean spreadsheet, and even drives the browser to create and share a Google Sheet. We go deep on how “agentic” work feels different when the model takes actions across your computer, your browser, and your tools. Then I shift into Boris’s viral workflow for Claude Code: parallel sessions, plan-first execution, Claude.md as a compounding team memory, and verification loops that dramatically improve output quality.

Key Points
- I use Cowork as a “doer,” not a chat: it touches files, browsers, and tools directly.
- I think about productivity as parallelism: multiple tasks running while I steer outcomes.
- I treat Claude.md as compounding memory: every mistake becomes a durable rule for the team.
- I run plan-first workflows: once the plan is solid, execution gets dramatically cleaner.
- I give Claude a way to verify output (browser/tests): verification drives quality.
