BUILDING A SMART DIARY APPLICATION

Abstract

The Smart Diary application is a cross platform journaling solution built with Flutter and Bloc for predictable state management, backed by Firebase Auth, Firestore, and Storage to deliver secure sign in, reliable persistence, and seamless sync across devices. Users can create rich entries that combine text, photos, videos, and voice notes; media is uploaded to Firebase Storage and referenced in Firestore so journals stay lightweight yet fully linked. An AI Analysis Service, powered by a Python backend, performs sentiment classification, topic extraction, entity detection, word and character counting, and summarization, returning actionable insights that drive self care suggestions and feed analytics widgets (charts, trends, and highlights). Location-aware recommendations use Geolocator/Geocoding and Google Place to surface relevant places, while Google Sign In shortens onboarding and keeps access controlled. Smart calendar hooks turn AI insights into reminders or recurring events, helping users act on their reflections. Environment configuration follows an IaC-style pattern and a decoupled API design, making it straightforward to scale services, roll out versioned updates, and redeploy with minimal manual steps. Together, these capabilities provide a resilient, low-downtime foundation for an intelligent journaling experience that combines privacy, usability, and continuous insight.
