Claude Cowork vs AI Agent Tools

The AI desktop agent landscape in 2026 is crowded. Here's how Claude Cowork compares to OpenAI Codex, Gemini CLI, Google Antigravity, Devin Desktop, Kimi Work, ZCode, and Tencent WorkBuddy — and which one fits your workflow.

The key difference in one sentence

Claude Cowork, Kimi Work, and Tencent WorkBuddy are built for knowledge workers — non-technical users who work with files and documents. The other five tools (Codex, Gemini CLI, Antigravity, Devin Desktop, ZCode) are built for developers — they require terminal knowledge, focus on code, and assume you're comfortable with Git, worktrees, and CLI workflows. If you write code for a living, several of these tools can complement each other. If you don't, Claude Cowork, Kimi Work, or WorkBuddy are your best options.
