Aider is a command-line tool for pair programming with an AI model. You start it inside a git repository, ask for a change, and it edits the files and commits the result, so every step is easy to review or undo.
It works with many AI models, which makes it popular with developers who like to compare providers or keep costs under control. It is a plain terminal tool with no graphical interface, which keeps it light and scriptable.
