BUD-E is a friendly AI assistant that runs on your phone, tablet, or computer. It can answer questions, search the web, create documents and presentations, generate images and music, and even search through education curricula — all through a simple chat interface with voice support.
Think of it as a personal assistant for students and teachers: you talk or type, and BUD-E helps you learn, create, and explore. It connects to AI services through a middleware server (Admin Bud-E) that your school or organization controls — so your data stays private and costs stay manageable.
