AI-Native IDE in plain English.

An AI-native IDE is a code editor built with AI as the organising principle rather than an add-on. Where GitHub Copilot began as autocomplete inside existing editors, tools like Cursor, Windsurf, Trae, and Zed treat the AI as a collaborator that can read the whole codebase, edit many files at once, run commands, and complete tasks in an agent mode, with the editor's interface reshaped around reviewing and steering that work. Most are forks of VS Code so the learning curve is gentle. The distinction from a plugin matters less each year as Copilot and JetBrains add the same features, but the AI-native editors still lead on how naturally the agent and the editor fit together. The cost is that your code is sent to model providers, which is why privacy-focused teams pair these editors with local or self-hosted models.
