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.
Clip, highlight and read the web with an AI reading assistant
Highlight text, images or links on a page with a shortcut, or drag, drop and right-click to save fragments and whole pages.
Generate automatic article summaries, ask key questions about the content, and let the assistant explain the main points.
The AI automatically marks important passages so the key ideas stand out before you start reading.
Read pages without clutter and keep a snapshot so saved content survives even if the original page changes or disappears.
