Copilot for CodeMirror is an open-source extension designed to enhance the CodeMirror text editor. The main feature of this tool is its ability to provide autocompletion suggestions, akin to GitHub Copilot, by utilizing OpenAI's Generative Pre-trained Transformer (GPT) models.

The tool can assist with coding by suggesting automatic code completions, enabling users to code faster and with less effort. It integrates seamlessly with CodeMirror and offers developers an improved coding experience by providing potential code solutions while they're typing.

GPT models have the capability to understand the context of the code being written, hence the suggestions made by the Copilot for CodeMirror extension are contextual, leading to improved speed and efficiency during the coding process.

The tool is available on npm for easy installation into your project. You may also refer to the GitHub repository for source code, feature requests, and support.

Please note that while it recommends use with specific models like GPT 3.5 Turbo, it does not mandate it. Developed by Asad Memon, the Copilot for CodeMirror extension is a handy tool for developers seeking to optimize their coding processes in CodeMirror.
