I built HighlightGPT because I was constantly losing my reading flow in ChatGPT. Whenever I highlighted a paragraph and wanted a quick explanation or translation, I had to copy it, open a new chat, paste it, ask again… and then scroll back to find where I was. It broke my focus every single time. So I made a tiny tool that fixes exactly that: highlight text inside ChatGPT and get the answer instantly — in a clean side panel that stays out of the way. You keep reading the main conversation, while all your follow-ups live neatly on the right. No new UI to learn, no context switching, and no extra tokens. Just a smoother way to read, think, and explore inside ChatGPT. Would love to hear how you use highlights in your workflow and what other one-tap actions you'd like next.
