What is 에이더 (Aider)?

Aider is a free, open-source tool that lets you pair-program with AI right in your terminal. Describe what you want and it edits files directly and even makes Git commits. The tool is free, but you bring your own API key (and usage cost) for models like Claude or GPT.

How to start in 5 minutes

  1. Install with 'pip install aider-install' in your terminal
  2. Get an API key for the model you want (e.g., Claude, OpenAI)
  3. Run 'aider' inside your project folder
  4. Type what you want and it edits the code for you
