Aider

Aider is an AI pair-programming tool designed to work directly with existing software projects from the terminal. Developers can connect it to supported language models and ask it to modify, create, or refactor code inside a Git repository. Aider builds a map of the codebase to help models understand how files and symbols relate, which is useful when making changes that span multiple parts of a project. Changes are applied directly to the working tree and can be committed to Git, creating a clear record of AI-assisted development. Developers can also use Aider for debugging, testing, documentation, and other coding tasks. Its terminal-first workflow makes it particularly suited to developers who prefer working close to their existing Git and command-line tools.
