Scenario Edge is an AI-powered web tool for scenario-based portfolio analysis that lets investors add stocks, ETFs, and crypto, run custom macro events, and receive evidence-grounded, per-asset projections with direction/impact labels, sensitivity mapping, plain-English rationales, and confidence scores backed by source citations. It helps individual investors and portfolio managers quickly stress-test "what if" scenarios (e.g., rate cuts, geopolitical shocks, AI spending booms) to see which holdings are most exposed and why, so you can assess risk and plan adjustments without manual research. The AI engine automates real-time evidence collection, classifies source quality, computes probability-aware confidence and sensitivity metrics, penalizes extreme/volatile calls, and generates explainable, traceable outputs to support transparent decision-making.
