Free, open-source AI coding tool that edits files directly in your terminal with automatic git commits. Works with Claude, GPT-4o, DeepSeek, and local models.
Aider is a terminal-based AI coding assistant that edits your files directly instead of showing you suggestions to copy and paste. You add files to the chat, describe what you want, and Aider modifies the code in place, then creates a git commit with a meaningful message. That workflow difference sounds small but changes how you interact with AI during development. You stay in your terminal, keep your git history clean, and avoid the context-switching overhead of IDE copilots.
The tool maps your entire repository to understand project structure, imports, and dependencies before making changes. When you ask it to add a feature that touches three files, it edits all three in a single operation with consistent imports and references. This repo-mapping is what separates Aider from simpler chat-with-code tools.
Renaming modules, restructuring packages, or migrating patterns across dozens of files. Aider's repo mapping handles cross-file dependencies that trip up simpler tools.
Building features that need coordinated changes to routes, models, tests, and documentation. Aider edits all files in one pass with consistent references.
Teams working on proprietary or classified code who need AI assistance without sending source to cloud APIs. Aider with local models keeps everything on your machine.
Developers who use vim, emacs, or work over SSH and want AI coding help without switching to a GUI IDE. Aider fits into existing command-line workflows.
