ChatGPT Vim Plugin

This Vim plugin brings the power of OpenAI's ChatGPT API into your Vim editor, enabling you to request code explanations or improvements directly within Vim. With this plugin, you can effortlessly highlight code snippets and ask ChatGPT to explain, review, or rewrite them, with the option to include additional context for better results.
