About Aider
What it is
Aider is an AI pair programmer that runs in the terminal and edits files in your local git repository. You tell it what to change, it makes the edit and commits it, so every change it makes is a commit you can read or undo. It is open source.
Why it's different
It is built around git rather than around a chat window, which makes it unusually easy to reverse: a bad suggestion is one revert away. It also brings no model of its own. You supply an API key and pay the provider per use, so the running cost is yours to watch and a long session on a large codebase is not cheap. There is no interface beyond the terminal, which suits some people and rules it out for others.
How people use it
Focused changes in a repository you already know, where the commit trail matters. Working on a server or in an environment where a graphical editor is not available. People who want AI editing without changing editors. Start it on a clean tree and add only the files relevant to the task, both to keep the cost down and to stop it wandering.
