Aider is a terminal-based AI pair programming tool that excels at making changes to existing codebases. It works with multiple AI models and has deep git integration, automatically creating well-structured commits for every change.
Aider's strength lies in its ability to understand and modify existing code rather than just generating new code. It can work with multiple files simultaneously and maintains awareness of your project's structure and dependencies.
With its terminal-native interface and git-first workflow, Aider is a favorite among developers who prefer command-line tools and want AI assistance that fits naturally into their existing workflow.
