## What is UniVault?

UniVault is an AI-powered knowledge management platform designed specifically for higher education institutions. It helps students and researchers find answers buried in thousands of PDF documents, lecture slides, and reference materials—instantly.

### The Problem

University knowledge is scattered across countless PDFs, Word documents, and lecture notes. Students spend hours searching through files for specific information, and valuable insights remain buried in academic papers.

### The Solution

UniVault centralizes all academic documents and makes them instantly searchable through natural language queries. Ask a question, get an answer with exact page references and citations.
