The Challenge
Decision-making typically relies on intuition and incomplete information. We developed shouldi.io to democratize access to analytical decision support — a capability previously available only through expensive consultants or complex analytical tools.
Our Approach
We built a modern web platform using Next.js and React 19 with TypeScript on the frontend, powered by Google Generative AI (Gemini) as the core AI engine. The system uses Cloud Firestore for secure, user-scoped data storage with full encryption. Interactive visualizations are rendered with Recharts, and the UI is built with shadcn/ui and Tailwind CSS for a polished, responsive experience.
Key Features
Probabilistic Modeling — generates outcome probabilities with confidence ranges across multiple dimensions. Instant Analysis — results delivered in seconds. Natural Language Input — simple, conversational question format. Scenario Comparison — side-by-side outcome analysis. PDF Export & Dashboard — shareable results and access to past analyses. Decision Templates — pre-built scenarios for common life decisions.
Results & Impact
Over 1,000 users have generated thousands of analyses with sub-5-second response times. The platform maintains full user privacy through encrypted, user-scoped data architecture and is available around the clock with consistent performance.
