Chat with your documents and YouTube videos
Upload a PDF or other document and ask questions about its contents in a conversational thread.
Paste a video link and get a digest of what is discussed without watching the whole thing.
Responses are drawn from the material you supplied, pointing back to the relevant section rather than answering from general knowledge.
Keep the context from earlier questions and narrow in on the exact detail you need.
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.
