ChatGPT infers which sense of a word fits the sentence you highlighted, instead of dumping every dictionary entry at once.
Matching dictionary entries and audio pronunciation are pulled in so you can hear as well as read the word.
Select text and click the purple circle that appears — no popup windows, no copy-pasting into a separate tab.
Add words you want to remember to a personal list so you can review them later.
