Bottom Line Up Front for every page, PDF and video you read
Extract the main points of any web page, PDF or YouTube video without reading or watching the whole thing.
Turn dense technical, academic or legal content into a simple explanation that is easy to digest.
Ask the assistant about specific points in the content to pull out exactly the detail you need.
Handles websites, PDF documents, YouTube videos and local files from a single interface.
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.
