Chat with an AI about whatever page you're reading
Open the extension on any site and ask questions about the content you're reading without copying links or text into another tool.
Responses are grounded in the page you're currently viewing, so you get explanations and summaries that fit the actual article or document.
Condense long articles or unpack unfamiliar terms and sections directly in a side panel, keeping your reading flow intact.
Install, click the icon, and chat. No configuration, no separate account, and no workflow changes required.
Chat with any PDF, video, or website and get cited answers in seconds
Every response is anchored to your source document with clickable citations that scroll to the exact passage, so verification takes seconds instead of page-by-page searching.
Organize documents into folders and query many files in a single conversation to compare arguments, cross-reference findings, or study a whole syllabus at once.
Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language.
Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.
