Localization
Dark/light modes with six accent colors, multi-language support, 12h/24h time toggles, and strict IANA timezone awareness.
Technical Architecture
Frontend Layer
UI is built using React 18 and TypeScript, bundled with Vite, and styled with Vanilla CSS. Dates are handled using date-fns.
Mobile Native Bridge
Android app uses Capacitor 6 bridging web frontend with native capabilities. Plugins for Firebase Auth, SQLite-backed local storage, and Android AICore.
Backend & Cloud
Serverless backend built with Node.js and hosted on Google Cloud Run. Leverages Firestore for persistence and Gemini 3.5 Flash for AI processing.
AI Routing Pipeline
Hybrid routing attempts local processing via Android AICore/local NLP first, falling back to cloud-based Gemini 3.5 Flash for heavier tasks like image/document parsing.
Security & Deployment
Firebase Auth persists locally. Validated server-side. Advanced endpoints require premium. Compiled via Gradle, deployed to Firebase EU region.
