aider is AI pair programming in your terminal

What it is

Aider lets you pair program with LLMs to start a new project or build on your existing codebase. Aider works best with Claude 3.7 Sonnet, DeepSeek R1 & Chat V3, OpenAI o1, o3-mini & GPT-4o, but can connect to almost any LLM, including local models. Aider makes a map of your entire codebase, which helps it work well in larger projects.

When to use it

Reach for aider when you want an AI to write, refactor or scaffold code in your editor or terminal — it's written in Python and fits stacks tagged anthropic, chatgpt, claude-3, cli.
