Dan Shipper is a man possessed by Codex. He calls it his daily driver, he’s been at inbox zero for 10 days straight (genuinely unlike him), and at a recent Anthropic event he spent his time telling the people who build Claude Code that they had to try Codex. He swears he isn’t sponsored by OpenAI. He’s just like this now.

At first glance, Codex looks just like another coding agent. In practice, it’s a workspace where you and AI agents can work side by side across your inbox, documents, data sources, and connected tools. You bring the context, judgment, and review. Codex helps gather inputs, produce artifacts, check work, and turn repeated processes into reusable workflows.

Today we published a power user’s guide to using Codex for knowledge work—even if you’ve never written a line of code. The guide covers:

• The Codex knowledge-work loop: Connect, contextualize, delegate or collaborate, review, and compound
• Workspace setup: how to create context files, rules, source folders, workflow documents, and review checklists
• The five levels of Codex use: from one-off tasks to multi-source workflows, recurring chores, small tools, and compounding systems
• 13 workflow templates: inbox review queues, unanswered message sweeps, research briefs, weekly reports, GTM plans, customer support routing, recruiting research, planning agents, and more
