AI tools for knowledge work
Codex vs Claude Code: which should a business team use?
Both are agents that can read files, write code and finish multi-step tasks. Codex comes with ChatGPT plans and suits teams already on ChatGPT. Claude Code, with Claude Cowork, suits teams who want an agent working through folders of documents and spreadsheets.
Most teams do not need to pick one forever. Choose the one that matches the business account you already have, learn it well, and revisit every few months as both change fast.
