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 your documents questions and see where every answer came from
Every answer comes with numbered citations; click one and the PDF opens at the passage, highlighted on the page.
Responses are drawn from your uploaded file rather than the open web or a model's memory, so you can verify every claim.
Handles contracts, leases, insurance policies, staff handbooks, research papers, tender packs and lecture slides.
If the document does not address the question, FileAI tells you instead of inventing an answer.
