Aider Chat

What is Aider Chat?

Aider Chat is an AI pair programming tool that edits code directly in your local git repository. It works with models including Claude 3.5 Sonnet, DeepSeek V3, o1, and GPT-4o. You can use it to add features, write test cases, describe bugs, refactor code, and update documentation. Aider handles complex requests by editing multiple files at once, commits changes to Git automatically with descriptive messages, and runs alongside your usual IDE or code editor.

What is Aider Chat used for?

• Edit code in a local git repository and switch between Aider chat and your code editor.
• Commit both your edits and the AI’s changes with clear, descriptive messages.
• Work with pre-existing, larger codebases — Aider can give models like GPT-4 a map of the entire git repository.
• Make coordinated changes across multiple source files in a single commit.
• Use chat commands to add or remove files, undo commits, display commit diffs, run shell commands, and request code changes by voice.
• Add images or URLs to the chat and have Aider read their content.
• Work with languages including Python, JavaScript, TypeScript, HTML, CSS, and PHP.
