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.
Turn noisy YouTube comment sections into a filtered stream of user feedback
Machine learning sorts every comment into categories so low-signal replies never reach your inbox.
Feature requests, bug reports and questions are collected and delivered as one consolidated stream.
Jokes, spam and emoji-only replies are filtered out, leaving only messages with product value.
You pay per thousand comments analysed, so the bill scales with your upload activity rather than a fixed seat.
