About Aider

Aider is an open-source command-line tool that acts as an AI pair programmer, letting developers edit an entire codebase through terminal conversations with models like Claude or GPT. It automatically handles git commits for AI-made changes and supports a wide range of programming languages. Built by developer Paul Gauthier, it has become popular among developers who prefer a terminal-first workflow over an IDE plugin.

Notable for: Terminal-first AI pair programming with automatic git commit handling
