Aider is an open-source, terminal-native AI pair programming tool created by Paul Gauthier that lets developers edit code across multiple files using natural language prompts. It integrates tightly with git, automatically committing changes with sensible messages, and supports over 100 LLMs including GPT-4, Claude, Gemini, and local models via OpenAI-compatible APIs. It composes naturally with editors like Vim and Emacs and is widely regarded as one of the most capable local coding agents available.
