Hey Product Hunt 👋 I’m Zhong Xin, the maker of HighlightGPT. I built this because when I’m reading long ChatGPT conversations, I kept losing context by copying text out to ask follow-ups or rewrite parts. HighlightGPT lets you highlight text *inside ChatGPT* and open a side panel to explain, ask, translate, or save memorizes — without tab switching or copy-paste. Would love your feedback: 1) When using ChatGPT, do you often run into a word or a specific part of the response that you don’t fully understand, and wish you could get an explanation for just that part instead of regenerating the whole answer? 2) Do you wish ChatGPT could respond more like annotations or inline comments on an existing answer, rather than simply continuing the conversation below it? Happy to answer any questions — thanks for checking it out 🙏

@xin_zhong This is a fantastic extension. I’ve run into this exact issue myself.

When I don’t grasp part of a GPT response, I highlight it and fire off a follow-up question. But the new reply buries the original answer, forcing me to scroll back up awkwardly.

Your tool elegantly fixes this simple yet frustrating gap that GPT overlooks.

Congrats on the launch!

@rohanrecommends Thanks so much, Rohan — really appreciate the kind words 🙏

That “losing context / awkward scrolling” moment is exactly the frustration that pushed me to build HighlightGPT, so it’s great to hear it resonates with you too.

One small thing worth clarifying: all the answers you get in the side panel are still generated by ChatGPT itself — HighlightGPT just changes how you interact with the existing response. There’s no extra model, no separate API calls, and no additional token cost involved.

Thanks again for the support, and congrats on spotting such a real UX gap 🙂

Hey this is interesting. Well done. Just curious, when you right click on highlighted text you can “ask ChatGPT” follow up questions. Why not do that instead?

@sunbash The main difference is where and how the answer appears.
“Ask ChatGPT” puts the answer at the bottom of the conversation, which breaks your reading flow.

HighlightGPT keeps the explanation alongside the highlighted text, more like an annotation, so you can understand that part without losing your place.
