Highlight any passage, right-click, and get a ChatGPT-powered summary in a pop-up
Highlight text, open the context menu, and pick SimpliSum to generate a summary without leaving the page or switching tools.
Results appear in a small pop-up over the current page, so you can compare the condensed version against the original passage side by side.
The listing describes summaries built on advanced machine-learning and natural language processing techniques powered by ChatGPT.
Rather than truncating, the extension is designed to identify the most important ideas, concepts, and details in the selected text.
