Open-source AI pair programming inside your terminal and git repo
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.
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.
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.
Connect hosted models from Anthropic, OpenAI, DeepSeek and others, or point Aider at a locally hosted model to keep code on your own hardware.
A minimal, extensible terminal coding agent you can reshape
Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
A dedicated AI-native code editor offering superior multi-file code generation, though it lacks terminal-native lightness.
