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.

A private AI chat workspace with file attachments and conversation history
Start conversations with a privacy-first framing so sensitive questions stay in a dedicated session.
Find earlier threads with a built-in conversation search rather than scrolling endlessly.
Attach files to a message so the assistant can work with documents you provide.
New chats, blog and settings sit in one collapsible sidebar so the workspace stays tidy.
