HighlightGPT

HighlightGPT helps you make sense of the text you come across while browsing. Simply highlight any word, phrase, or concept on a webpage, and HighlightGPT will explain it using the content of that very page, so the answer always fits the context you are reading.

Powered by your own OpenAI API key, HighlightGPT delivers clear explanations in seconds. You can choose from different levels of context, letting you control how much background detail you get and keeping every explanation as relevant as possible.

Whether you are a student, a professional, or a curious reader, HighlightGPT is designed for those moments when an unfamiliar term or confusing concept stops you mid-read. Instead of breaking your flow to search elsewhere, get a quick, context-aware explanation right where you are.
