About Aider

Aider is an open-source, terminal-based pair programmer that edits code in your local git repository and commits the changes. You run it with your own API key, for example `aider --model sonnet --api-key anthropic=`, and it works with Claude, OpenAI and DeepSeek models among many others. It builds a map of your codebase so the model can work on large existing projects.
