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.

AI Q&A Chrome extension for your private knowledge and the open web
Ask questions in natural language and get AI-generated answers instead of scanning documents manually.
Designed to query an organization's or individual's own internal knowledge, not just the public web.
Falls back to publicly available internet data so answers are not limited to what you have uploaded.
Installs as a small browser extension (about 1 MB) so it is available wherever you are already working online.
