Editorial buying guide
AI coding tools work best when they understand the project context and when developers review every change. Autocomplete is useful, but the real productivity gain comes from codebase-aware chat, refactoring help, test generation, and explaining unfamiliar files.
Cursor is suited to developers who want an AI-first editor experience. GitHub Copilot is strong for broad IDE support and enterprise adoption. Windsurf offers a friendly route for budget-conscious builders. Claude and ChatGPT remain useful for architecture thinking and debugging explanations.
The safest workflow is to ask the tool for a small change, inspect the diff, run tests, and then expand the task. Teams should avoid pasting secrets into prompts, should keep generated code under review, and should measure whether AI assistance improves delivery quality, not just typing speed.
