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.

Governed knowledge management for your people and your AI agents
Every document has an owner, an expiry date and an approval path, so knowledge stays verified and current rather than drifting quietly out of date.
Validity and expiration reminders, feedback management, review and multi-step approval workflows, plus gap and duplicate detection to surface what is missing or redundant.
Serve the same governed content to ChatGPT, Claude, custom agents and copilots through MCP, RAG, REST APIs and a browser extension, with citations and one permission model.
Multilingual editor, decision trees and automatic translation help distributed operations, service and IT teams answer in their own language.
