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.

A secure AI pilot for your email, calendar, meetings and business data
A daily brief and daily plan assemble the day's priorities from your connected calendar, email and messages so you start with context instead of a backlog.
Incoming email and messages are triaged, prioritised, and drafted replies are written in your tone, with items sorted by the action you need to take.
Smart scheduling protects focus blocks and prepares pre-meeting briefs, so you walk into every conversation already informed.
Ask plain-English questions across CRM, finance, ops and internal tools and get direct answers with sources rather than another dashboard to interpret.
