Aider brings AI-assisted programming into the environment many developers already trust: the terminal. Instead of moving code into a separate chatbot, you can point Aider at an existing repository and work with an AI pair programmer directly alongside your project. It can understand multiple files, make coordinated code changes, create commits, inspect and fix bugs, and use your project’s Git history as part of the workflow. With support for a wide range of language models, Aider gives developers the freedom to choose the model behind their coding assistant while keeping the development process grounded in the actual codebase.
