Aider - AI Terminal Pair Programming Assistant

Project Overview

Aider is a tool that lets you pair program with large language models (LLMs) to start new projects or develop on existing codebases. It's a revolutionary AI programming assistant that provides intelligent programming support through a command-line interface, hailed as "GitHub Copilot in your terminal."

Core Features

🤖 Multi-Model Support

Aider performs best on Claude 3.7 Sonnet, DeepSeek R1 & Chat V3, OpenAI o1, o3-mini & GPT-4o, but can connect to virtually any LLM, including local models.

🗺️ Intelligent Code Mapping

Aider creates a map of your entire codebase, which helps it work well on large projects. This codebase understanding allows the AI to accurately understand project structure and context.

🌐 Multi-Language Support

Aider supports most popular programming languages: Python, JavaScript, Rust, Ruby, Go, C++, PHP, HTML, CSS, and dozens more.

📝 Automatic Git Integration

Aider automatically commits changes and generates reasonable commit messages. Easily diff, manage, and undo AI changes using familiar git tools.

🎤 Voice Programming

Discuss your code with aider using voice! Request new features, test cases, or bug fixes via voice, and let aider implement those changes.

🖼️ Multimedia Support

Add images and web pages to the chat to provide visual context, screenshots, reference documentation, etc.

🔧 Automatic Testing & Checking

Automatically check and test your code every time aider makes a change. Aider can fix issues detected by checkers and test suites.

🌐 Web Interface Compatibility

Collaborate with any LLM's web chat interface. Aider simplifies the process of copying and pasting code context and edits back and forth in the browser.

Installation & Usage

Quick Install

python -m pip install aider-install
aider-install

Basic Usage

# Go to your project directory
cd /to/your/project

# Use DeepSeek
aider --model deepseek --api-key deepseek=<key>

# Use Claude 3.7 Sonnet
aider --model sonnet --api-key anthropic=<key>

# Use o3-mini
aider --model o3-mini --api-key openai=<key>

Performance

SWE Bench Benchmark

Aider has a top score on SWE Bench. SWE Bench is a challenging software engineering benchmark where aider solves real GitHub issues from popular open-source projects like django, scikit-learn, matplotlib, and more.

Technical Advantages

Precise Code Modifications

Unlike other AI programming tools, Aider focuses on making precise, surgical modifications to existing codebases, rather than rewriting entire files from scratch.

Contextual Understanding

By creating a map of the codebase, Aider can understand the structure and dependencies of complex projects, providing more accurate suggestions and modifications.

Version Control Integration

Deep integration with Git ensures that every AI change has proper version control records, making it easy to roll back and collaborate.

IDE Integration

Use aider in your favorite IDE or editor. Request changes by adding comments to your code, and aider will get to work.

Use Cases

• New Project Development: Quickly launch and set up project architecture
• Existing Code Maintenance: Refactor, optimize, and fix existing codebases
• Feature Addition: Add new features to existing projects
• Bug Fixes: Intelligently identify and fix code issues
• Test Writing: Automatically generate unit tests and integration tests
• Code Review: Analyze code quality and provide improvement suggestions
