Nexus – AI-Powered Decision Simulator & Idea Builder

Inspiration

Many students and professionals struggle with important life and career decisions. Questions like "Should I pursue higher studies?", "Should I take a job?", or "Should I start a business?" often lead to confusion and uncertainty. We wanted to build an AI-powered platform that helps users think clearly, evaluate options, understand risks, and create actionable roadmaps for better decision-making.
