# Aider — AI Pair Programming in Your Terminal

> Chat with Claude or GPT to edit code in your local git repo. Aider understands your whole codebase, makes multi-file edits, and auto-commits changes.

## Install

Save as a script file and run:

## Quick Use

```bash
pip install aider-chat
cd your-project
aider --model claude-sonnet-4-20250514
```

Start chatting. Aider edits your files and git-commits each change automatically.

## What is Aider?

Aider is a terminal-based AI pair programmer. It maps your entire repo into context, lets you ask for changes in natural language, and applies multi-file edits directly to your working tree — with automatic git commits for easy review and undo.

**Answer-Ready**: Aider is a CLI AI pair programmer that edits code across multiple files in your local git repo, supporting Claude, GPT-4o, and other models with automatic git commits.

## Core Features

### 1. Whole-Repo Context
Aider builds a repo map so the AI understands your project structure:

```bash
aider --model claude-sonnet-4-20250514
> /add src/api/*.py  # Add specific files to context
> refactor the auth middleware to use JWT
```

### 2. Multi-File Edits
One prompt can modify multiple files simultaneously:

```
> add a /health endpoint with tests
# Aider edits: src/routes/health.py, tests/test_health.py, src/app.py
```

### 3. Auto Git Commits
Every change is committed with a descriptive message:

```
git log --oneline
a3f2b1c Add /health endpoint with unit tests
9e1d4a7 Refactor auth middleware to use JWT tokens
```

### 4. Model Flexibility

```bash
aider --model gpt-4o           # OpenAI
aider --model claude-sonnet-4-20250514   # Anthropic
aider --model deepseek/deepseek-chat  # DeepSeek
aider --model ollama/llama3    # Local via Ollama
```

### 5. Architect Mode
Use a strong model for planning, cheaper model for coding:

```bash
aider --model claude-sonnet-4-20250514 --architect
```

## Key Commands

| Command | Action |
|---------|--------|
| `/add file` | Add file to context |
| `/drop file` | Remove file from context |
| `/diff` | Show pending changes |
| `/undo` | Undo last AI edit |
| `/run cmd` | Run a shell command |
| `/test` | Run tests |

## FAQ

**Q: How does it compare to Claude Code?**
A: Aider focuses on chat-driven edits with auto-commits. Claude Code offers broader tool use (bash, web, MCP). They complement each other well.

**Q: Does it support Claude?**
A: Yes, Claude Sonnet and Opus are first-class supported models.

**Q: Can it handle large repos?**
A: Yes, the repo-map feature intelligently selects relevant context without exceeding token limits.
