About Aider
Aider is an open-source tool for AI pair programming from a terminal. It lets developers work with large language models (LLMs) to start a new project or change an existing codebase. Aider builds a map of the whole codebase, which the source says helps it work in larger projects.
Aider supports many common programming languages and commits its changes to git with descriptive messages, so changes can be reviewed, managed, or undone with standard git tools. It can also lint and test code after each change. The getting started examples show connecting to hosted models with a provider API key, and the source states that Aider can also connect to local models.
