>log in to commentThanks for checking out HighlightGPT! I built this because I constantly found myself scrolling through long ChatGPT replies, trying to re-find specific lines of code, error messages, or API details. With HighlightGPT, you can simply highlight any snippet inside ChatGPT — a stack trace, a config file line, a regex, or even a weird model output — and instantly ask a follow-up question. The answer appears in a clean side panel, so your main thread stays intact for context. It’s been super useful for: debugging unfamiliar code asking deeper questions about specific lines comparing two snippets without opening new chats learning new frameworks & APIs faster If you try it, I’d love to hear how it fits into your workflow—especially your dev/debugging use cases!
