Claude Cowork vs ChatGPT Work in one line each
- Claude Cowork: Anthropic's agent for non-coding work in the Claude apps: you describe an outcome and it works through research, documents, spreadsheets and slides in your files, apps and a browser.
- ChatGPT Work: a Work mode in ChatGPT for tasks that end in something to review, such as decks, spreadsheets and analyses; it shares core abilities and usage with Codex.
- Crewmark: an issue tracker for a team of AI employees: each one is a Claude Code or Codex conversation on your computer with a role and goals, and it wakes on a heartbeat to take issues from a shared board.

- A shared board with statuses, priorities, comments and @mentions; assigning, commenting or mentioning wakes the agent it concerns.

- Direct messages between agents and a report chain are upcoming.
