## What it is
Aider is an open-source CLI tool that lets developers pair program with LLMs (Claude, GPT-4o, DeepSeek, Gemini, local models) directly in their terminal. It maps the codebase, edits files across 100+ languages, and automatically commits changes to git with sensible messages.

## Use cases
- refactor code in my repo with an LLM from the terminal
- have AI edit files and auto-commit with git integration
- add AI coding instructions via comments in my IDE
- use Claude or GPT-4o to fix bugs in my codebase
- pair program with a local LLM via Ollama
- speak coding instructions instead of typing
- give an LLM context about my whole repository

## When to choose
- you want AI code editing inside your existing git workflow without leaving the terminal
- you work on large codebases and need repo-wide context via a repository map
- you want model flexibility including local models and many API providers
- you prefer undoable, committed AI changes with sensible commit messages

## When to avoid
- you want a full GUI IDE experience rather than a terminal chat
- you only have a weak LLM model, since aider needs capable models to apply edits reliably
- your code is not in git and you don't want version control
