Aider

Aider is a unique, terminal-based AI coding assistant that uses GPT-4 or Claude directly from the command line to edit code in your local repository. It integrates with Git, allowing it to see diffs and make committed changes. You chat with it in plain English, and it proposes edits to your files. Its key feature is working directly with your existing editor and tools, acting as a chat-based pair programmer in the terminal.

It targets developers who prefer a keyboard-centric, terminal-based workflow and want an AI assistant that respects their existing toolchain (like Vim, Emacs) without forcing a new IDE. It's a minimalist but powerful approach.
