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.
Ask questions about the page you're reading, answered by an LLM
Pose a question about the material on your active tab and get an answer generated by a large language model using that page as context.
Handles reading material such as articles, product pages and YouTube video pages, not just plain text documents.
Each tab keeps its own conversation, storing only the five most recent chat histories and capping tabs at 80 chats before older ones are cleared.
A download button saves the current tab's chat history as a PDF so you can keep or share the answers.
