📖 Overview
CovenantPromptKey is a web application designed specifically to protect sensitive information, enabling you to safely mask confidential content when using AI services. Through an intuitive keyword mapping system, you can replace company names, product codes, personal information, and other sensitive data with secure alternative terms. After receiving AI responses, you can restore the alternative terms back to the original sensitive content.
Additionally, this application integrates a Bible Search System that provides Scripture search, reading, and interactive game features.
Hosting Model (WebAssembly-first, Dual-hosting)
- Primary (browser-hosted / Blazor WebAssembly): Can be deployed as pure static assets (GitHub Pages / Azure Static Web Apps) and supports offline-first (can be launched offline after successfully loading once).
- Legacy fallback (Blazor Server): Maintains existing Server hosting for compatibility and fallback; currently both versions maintain feature parity, but future development will focus primarily on the Web (WASM) version.
PWA / Service Worker Notes (Update behaviour)
This project's browser-hosted version (GitHub Pages / Azure SWA) uses Service Worker for offline-first support; therefore, browsers may temporarily reuse cached assets when the deployment environment updates.
- Development environment (localhost): Service Worker is not registered by default, and attempts to clear existing registrations/caches to avoid false positives of "no updates."
- Deployment environment (e.g., GitHub Pages): If you encounter outdated versions, first close all tabs and reopen; if still not working, perform a Hard Refresh (Ctrl+F5) or clear that site's Site Data.
