Private Tool - AI
Lecture analysis assistant grounded in your course materials
A private AI workspace that extracts, highlights, and analyzes lecture materials, then helps complete assignments and exams using only the uploaded content.
Private Tool - AI is a personal study system for organizing courses and turning lecture files into usable analysis.
Upload PDF, Word, PowerPoint, text, and images. The assistant (Dian) extracts text, including OCR from photographed slides, then highlights formulas, theories, and researchers so the material is searchable. Assignments and exams are answered only from the uploaded sources. If the model steps outside the material, the answer is flagged. Courses, meetings, student identity, campus data, and export-ready documents keep the workflow complete from reading to submission.
