What is Aider?
Aider is a command-line tool that lets you pair program with an LLM. It can read your local codebase, write new features, fix bugs, and automatically commit the changes to Git.
Unlike Copilot which suggests a few lines at a time, Aider is an agent that takes a high-level command ('add a dark mode toggle') and executes the changes across multiple files, complete with a git commit.
