Developer releases open-source ChatGPT sidebar conversation navigation plugin built with AI

On October 23, 2026, a developer posted on V2EX about a browser extension they built for the ChatGPT web interface. The post explained that in long ChatGPT conversations, jumping back to an earlier question or answer requires slowly scrolling through the chat history. Having noticed that deppseek offers a tidy side panel for jumping between conversations, the developer decided to build a similar extension for ChatGPT. The extension adds a DeepSeek-style hover navigation panel on the right side of the ChatGPT web page, letting users jump directly to any past question in the conversation. According to the post, the project was written entirely with AI assistance. The source code is open-sourced on GitHub at https://github.com/C-C-Lucky/chatgpt-nav-extension, and the developer added a note asking for feedback on parts that may not be well polished. This V2EX post is the only report available so far, and no follow-up updates or community feedback on the extension have appeared in the source material.
