HighlightGPT is a Chrome extension that lets you highlight text inside ChatGPT and open a side panel to ask AI, explain, ask, translate, or save memorizes. It’s a small workflow upgrade that makes ChatGPT feel more like a reading & thinking workspace.
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 🙏
ChatGPT’s UI changes often and extensions can be fragile—what did you optimize for to keep the experience reliable over time, and what tradeoffs did you make between “deep integration” and “breakage risk”?
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?
