Aider is an open-source command-line AI pair programming tool that works directly in your Git repository, making coordinated multi-file edits, running tests, and committing changes with descriptive messages. It supports many LLMs (GPT, Claude, Gemini, local models via Ollama) and uses repo maps to give the model context across large codebases efficiently. Aider is known for its diff-aware editing, test-driven workflow, and lightweight terminal UX.
