What is Aider?
Aider is an open-source AI pair programming tool that runs entirely in your terminal. You add files to the session, describe what you want changed, and it makes coordinated edits across multiple files, then automatically commits the changes to git with a descriptive message. It works with OpenAI, Anthropic Claude, and local models via Ollama — you bring your own API keys, so there's no separate subscription beyond model costs.
What is GitHub Copilot?
GitHub Copilot autocompletes code as you type, powered by OpenAI Codex. It's like autocomplete on steroids — suggests entire functions, test cases, and implementation patterns based on your context. Works across all major languages and integrates directly into VS Code, JetBrains IDEs, and Neovim. The suggestions are often correct enough to accept with minor tweaks.
