About Aider

Aider is a command-line tool that pairs with AI models to edit your code in real-time. Unlike GUI-based assistants, Aider lives in your terminal and works directly with your git repository. It's designed for developers who prefer keyboard-driven workflows and want precise control over AI-assisted changes. Aider can edit multiple files simultaneously, run tests, fix bugs, and even implement features from scratch โ€” all through natural language commands. It supports multiple LLM backends and integrates seamlessly with your existing git workflow.

Key Features

Real-time multi-file editing via terminal
Direct git integration for version control
Supports multiple LLM backends
Automatic test running and bug fixing
Bulk refactoring across codebase
