AI coding assistants mainly differ by where they run, how much work they can perform, and which models they support. GitHub Copilot focuses on editor and GitHub workflows. Cursor and Windsurf are AI-focused editors with codebase search and agent features. Claude Code and Aider work mainly from the terminal. JetBrains AI tools are built into JetBrains IDEs, while Continue offers an open-source, bring-your-own-model option.
Choose by workflow rather than brand. Compare editor support, repository context, model choice, privacy controls, command permissions, and pricing. An editor assistant is useful for quick suggestions while typing. A terminal agent is often better for multi-file changes, running tests, and automation. Teams should also check enterprise policy controls and whether code is retained or used for training.
