ReflectIQ — AI Journal & Cognitive Bias Insight Engine

Built for Google Cloud's #AccelerateAIwithCloudRun Ideathon. Authenticated with Firebase, holds multi-turn conversations with the Gemini API, and persists entries to Firestore with strict per-user isolation enforced by security rules — the Gemini API key is retrieved at runtime from Google Cloud Secret Manager, never hardcoded. Configured Google AI Studio's Custom Instructions with enterprise security directives before writing any code, so the app was built security-first from the ground up. Original feature: a Cognitive Bias Insight engine that analyzes journal entries for decision-making patterns — loss aversion, FOMO, sunk cost, confirmation bias — and returns a reflection prompt.
