Aider lets you pair program with LLMs, to edit code in your local git repository. Start a new project or work with an existing git repo. Aider works well with GPT-4o, Claude 3 Opus, GPT-3.5 and can connect to almost any LLM.
See the installation instructions for more details, but you can get started quickly like this:
$ pip install aider-chat
# To work with GPT-4o
$ export OPENAI_API_KEY=your-key-goes-here
$ aider
# To work with Claude 3 Opus:
$ export ANTHROPIC_API_KEY=your-key-goes-here
$ aider --opus
