AI 编程工具对比：补全、编辑器和命令行助手

AI 编程工具不是单一品类。GitHub Copilot 和 Codeium 更偏代码补全；Cursor、Windsurf 更偏 AI 编辑器；Claude Code 这类工具适合命令行与代码库级任务；v0、Bolt、Lovable 更适合从需求生成页面或原型。

团队选择时要看代码隐私、IDE 兼容性、模型能力、上下文长度和是否适合现有工程流程。个人开发者可以先从低成本工具开始，再按项目复杂度升级。

English: AI coding tools serve different workflows. Completion tools help inside the editor, AI IDEs support larger edits, CLI agents operate across projects, and website builders are useful for prototypes.
