About

What It Is

Aider is a terminal-based AI coding assistant for developers who want to work with an AI pair programmer directly in their codebase. The documentation positions it as “AI pair programming in your terminal,” and it is aimed at people editing, reviewing, and iterating on software projects.

What to Know

Aider looks more like a coding copilot than a fully autonomous agent. The crawled docs clearly show it taking action on code in your repo and watching files for changes, but they do not show it independently completing broader software tasks without user direction.

Key Features
Terminal-based AI coding workflow
Edits code in the context of your project repository
Supports xAI models such as Grok 3 and Grok 3 Mini
Can list available models from a provider
Supports a `--reasoning-effort` flag for Grok 3 Mini models
Use Cases
Pair-program with an AI assistant while staying in the terminal
Use Grok models to edit or review code in an existing repository
Watch a codebase for changes and add AI coding instructions during development
