Aider is a terminal-based AI pair programmer that works with code in a local repository. It connects to supported cloud or local language models, uses a map of the codebase to provide context, and can coordinate changes across files. Its Git integration helps developers inspect and manage the changes produced during a coding session.
The workflow is a good fit for developers who want conversational editing without making a graphical AI editor the center of their setup. Aider also supports linting and testing workflows, so an edit can be checked against the project rather than accepted only because the generated explanation sounds plausible. The software and the model service are different parts of the setup: review model access, privacy, and any provider charges separately.
For a first trial, use a small repository with tests and a recoverable Git history. Define a bounded change, select the relevant files, and inspect the resulting diff before committing it. Terminal access makes careful control of project context and commands important; it does not replace code review.
Use a failing test as the starting point for a repair. After the change, check that the test passes for the right reason and that adjacent behavior still works. Compare total review time, model costs, and unnecessary edits across tools instead of comparing only generation speed.
