Aider

Aider is an AI pair programming tool that runs in your terminal and works directly with your existing code repository. It uses LLMs to help you write, change, and improve code without leaving your normal development workflow.

Terminal-first AI coding assistant

Use natural language to start new projects or extend an existing codebase. Aider reads repository context and helps you apply changes while keeping the project structure intact.

• Generate new code and files
• Refactor existing code
• Propose edits based on repo context

Built for real developer workflows

Aider is designed for developers who prefer the terminal and version control. It can speed up everyday tasks and help you work in large codebases.

• Navigate and understand large repositories
• Explain complex sections of code
• Support day-to-day coding tasks in a familiar environment

Open ecosystem

Aider integrates with popular AI providers through OpenRouter, letting you use different models within the same workflow.
