Common Questions & Answers about Aider
What is the main problem Aider solves?
Aider solves the “context gap” and friction of manual copy-pasting during AI-assisted development. By working directly in your terminal, it acts as an AI Coding Assistant that understands your whole project structure, allowing it to edit multiple files at once while ensuring every change is tracked and committed to Git.
How does Aider compare to GitHub Copilot?
While Copilot is a predictive autocomplete plugin, Aider is a proactive AI Pair Programmer. Aider can architect entire features across several files and manage your Git workflow, whereas GitHub Copilot is primarily designed for real-time line-by-line suggestions within the IDE.
Can I use Aider for free?
Yes, Aider is an open-source tool and is completely free to install and use. You only incur costs from your chosen AI provider (like Anthropic or OpenAI) for the API tokens consumed during your coding sessions, or you can run it entirely for free using local models.
The Jumpstart
Install Aider instantly by running pip install aider-chat in your terminal and typing aider inside any Git repository to begin your first AI-powered session.
