HighlightGPT

Highlight any sentence, get an instant, page-aware AI explanation

In-place explanations

Highlight a confusing sentence and receive a short explanation without leaving the page or opening another tab.

Three context levels

Choose how much surrounding page text is sent along with your selection to balance answer quality against API cost.

Automatic request trimming

When a selection plus page context exceeds the request size limit, the extension automatically lowers how much page content it ingests.

Double-click protection

Accidental highlights created by double-clicking are ignored, so the tool only fires when you deliberately select text.

+Explanations use surrounding page text, so answers match the article rather than a generic definition
+No context switching — you stay on the page you are reading
+Adjustable context depth lets you control how much you spend per explanation
