Aider

Open-source AI pair programming inside your terminal and git repo

Terminal-native pair programming

Chat with an AI assistant from your shell, have it propose and apply code edits to files in your working directory, and keep full control of the final diff.

Deep git integration

Every accepted change becomes a real commit with an auto-written message, so you can inspect, amend, revert or branch AI edits with ordinary git commands.

Repository-wide code map

Aider builds a structural map of your project so the model understands where relevant code lives and can work sensibly in large, multi-file codebases.

Broad model support

Connect hosted models from Anthropic, OpenAI, DeepSeek and others, or point Aider at a locally hosted model to keep code on your own hardware.
