Aider

Overview

Aider is a command-line coding assistant with an unusual and, in practice, excellent design decision: it treats git as the interface. Every change it makes lands as a commit with a sensible message, so reviewing, reverting or bisecting the AI's work uses the tools you already have rather than a proprietary diff viewer. It builds a repository map to give the model structural context without dumping the whole codebase into a prompt, and it works with essentially any model you have a key for. Because it lives in the terminal, it slots into whatever editor you already use instead of asking you to adopt a new one. The trade-off is bluntness. There is no GUI, no click-to-accept, no agent dashboard — you converse, it edits, it commits. On very large monorepos the repo map starts to strain, and you will spend time telling it which files matter. For developers who already live in a terminal, that is a feature.

Features

Automatic git commits for every AI-generated change

Repository map that gives the model structural context without full-repo dumps

Works with most major models via your own API key, including local models

In-chat commands to add, drop and scope specific files

Voice input and image/URL context support

Lint and test hooks so it can run your suite and fix what it breaks

Cons

Terminal-only; if you want a visual diff-and-accept flow, this is the wrong tool
Repo map degrades on very large codebases and needs manual file scoping
