How to Set Up AI Pair Programming (2026 Guide)
Your AI coding partner that understands your entire codebase. Write better code, faster.
😫 The Problem
Writing code takes hours. Debugging takes longer. You need help, but hiring a developer is expensive. Traditional AI assistants only see one file at a time.
✨ The Solution
AI pair programming tools understand your entire repository, make multi-file changes, and write tests automatically. Free options like Aider run in your terminal. Paid options like GitHub Copilot integrate with your IDE.
Step by Step
Choose your tool: Free and powerful (Aider, Claude Code) or integrated (GitHub Copilot, Cursor)
Option 1 - Aider (Free): Install via pip: pip install aider-chat. Run: aider in your project directory. Connect to Claude, GPT-4, or local models.
Option 2 - Claude Code (Anthropic): Download from claude.com/code. Works in terminal with full repository context. Best for complex refactoring.
Option 3 - GitHub Copilot ($10-39/mo): Install VS Code extension. Sign up at github.com/features/copilot. Chat and autocomplete in your IDE.
Option 4 - Cursor (Free tier): Download cursor.sh. Fork of VS Code with AI built-in. Great for beginners.
Connect to your model: Aider and Claude Code work best with Claude 3.7 Sonnet or GPT-4o. Get API key from anthropic.com or openai.com.
Start your first session: cd your-project && aider. Try: 'read all files and understand the architecture'.
Make your first change: Ask: 'Add authentication to the login endpoint' or 'Refactor the database queries'.
Review changes: Aider shows diffs before committing. Always review AI-generated code.
Best practices: Write clear prompts. Review every change. Use git commits to track AI work. Run tests after major changes.
