Ask questions and get instant answers from any web page you are reading
Ask questions about the article you are reading and see answers rendered inside the page, with no tab switching or copy-pasting into a separate chat window.
Generate a condensed summary of long articles, documentation, or blog posts so you can judge relevance before committing to a full read.
Highlight a passage or a concept you did not follow and request a plain-language explanation tied to the surrounding context.
Beyond summaries, the extension accepts free-form requests such as author background, definitions, or background context for any page you visit.
