What happened to the URL on file for Copilot for CodeMirror?

URL unreachable The URL on file (https://copilot.asadmemon.com/) did not respond across three consecutive checks; the streak completed on 2026-09-19.

This reports what that URL did, not a claim that Copilot for CodeMirror itself is gone: the address on file does not confidently match Copilot for CodeMirror's own domain, so if it turns out to be a marketplace or listing page rather than Copilot for CodeMirror's own site, this observation is still accurate about the URL, just not about the product. See the methodology for how the match is made.

The vendor's own description, unedited:
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.
