About HighlightGPT

Don't understand something? Just highlight it on the page, and HighlightGPT will explain it to you in MERE SECONDS, using mainly content from the page you are on to maximize relevance! Choose between 3 different levels of context, the more the merrier, of course. Higher values for context will use more text from the page. HighlightGPT generates context with the information surrounding your highlighted text. If the request size is too big, HighlightGPT automatically decreases the page ingest amount! Requires an OpenAI API key! HighlightGPT intentionally ignores highlights made by double clicking. Careful, high values might eat into your OpenAI quota!
