Aider

Aider is a terminal‑based assistant that lets developers converse with large language models to write, edit, and understand code. It can connect to a wide range of cloud and local LLMs, including Claude 3.7 Sonnet, DeepSeek, and OpenAI models, and it builds a map of the entire codebase so the AI can navigate larger projects. The tool supports over a hundred programming languages, from Python and JavaScript to Rust, C++, and HTML, and it integrates with Git to create sensible commit messages and allow standard diff, revert, and history workflows.

The assistant can be invoked from within an IDE or editor by adding comments to source files, and it also accepts images, web page URLs, and voice input to provide visual or spoken context for code changes. Users can request new features, test cases, or bug fixes through natural language, and Aider will generate the corresponding modifications. By handling linting, testing, and version control interactions, it aims to streamline the pair‑programming experience directly in the developer’s existing workflow.
