What is Aider?

Aider is a terminal-based AI coding assistant that lives in your command line and works directly with your git repository. Unlike web-based tools, it lets you chat with AI about your code while automatically committing changes with descriptive messages. It supports multiple LLMs (GPT-4, Claude, local models) and can edit multiple files at once while maintaining full version control.

Built for developers who prefer working in the terminal, Aider excels at refactoring, bug fixes, and feature implementation across entire codebases. The open-source approach means no vendor lock-in, but you'll pay LLM API costs directly - which can add up fast at roughly 70 cents per command.

Real quotes with sources

“Aider is free, can hookup to whatever model you want, has a *really* good terminal interface that makes it easy to do the usual file inclusions”

format_quote

“I am experimenting with both Cursor and Aider and find them great, but it is difficult to review changes coming from Aider.”

format_quote

“My conclusion is Aider is ACTUALLY effective as a tool in getting things done. But, it is mostly useless in the hands of someone that doesn't”
