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.

AI-powered digital asset management that makes every file findable
Every upload is scanned, described and tagged automatically so assets become searchable without manual metadata entry.
Describe what you need in plain words and get instant, accurate results across the whole library instead of digging through folders.
Create external links that let anyone view or download assets, even collaborators who do not have a contentcloud login.
Storage expands from hundreds of files to millions, with version history so teams can track and roll back asset changes.
