Quick Verdict
Choose Cursor if you want a full-featured, AI-native IDE for daily development. Choose Aider if you prefer a free, terminal-based tool that integrates into your existing editor workflow.
Cursor is a standalone, AI-integrated editor (based on VS Code) that provides a seamless, GUI-driven experience for writing and refactoring code. Aider is a CLI tool that acts as an AI pair programmer, making edits directly to files in your local repo from the terminal.

Cursor costs $20/month, whereas Aider is free, appealing to different budgets and workflow preferences.
