HighlightGPT is a browser extension built for people who live inside ChatGPT every day — especially developers.
Instead of copying code snippets, stack traces or API responses into new chats, you simply highlight text directly in ChatGPT and trigger one-tap actions: ask, explain, simplify, translate, or save it for later.
All follow-up answers open in a slim side panel, so your main conversation stays intact and you never lose context. This makes it great for:
- debugging and understanding complex error messages
- exploring unfamiliar code or libraries
- learning new frameworks and APIs
- keeping research notes without leaving ChatGPT
It works entirely inside ChatGPT’s native web experience
