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.

Return cleaned page text and AI-extracted highlights so agents receive the most relevant excerpts instead of entire pages.
Choose fast, balanced or deep search modes so an assistant can answer instantly or run longer grounded research.
Extract structured outputs such as company details, people and other entities for list building and data pipelines.
