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 summaries of customer reviews so you can judge a business at a glance
Condenses large volumes of customer reviews and public feedback into a short, readable digest instead of a wall of individual posts.
Surfaces the overall balance of positive and negative opinion so you can gauge whether sentiment is broadly favorable or divided.
Highlights the topics reviewers mention again and again — pricing, support, reliability, quality — rather than isolated one-off remarks.
Presents findings in a structure meant to support a purchasing or vendor decision rather than to entertain or promote.
