What is Aider?
Aider is an open-source AI coding assistant that runs in the terminal and edits files in your local git repository.
What does it do?
Takes an instruction in chat, edits the relevant files directly, and commits each change to git with a written message. Builds a map of the repository for context and connects to most LLM providers using your own API keys.
Who is it for?
Developers who live in the terminal and want an agent that edits a real codebase, and anyone who prefers bringing their own model and API key.
