Why Reborn?
- Universal Multi-Platform — Web/PWA (Chrome, Safari, Edge, Firefox), Desktop (Windows, macOS, Linux), and Native Android with 100% project compatibility
- In-Browser & PWA Offline — Run directly in any browser on Chromebooks, iPads, and PCs, or install it as an offline standalone app
- Responsive Mobile Layout — Dynamic scaling for sub-740px smartphone displays with pixel-accurate touch coordinates
- More room to create — 10 pages per project, a scrollable page strip, an expanded character sidebar, and + buttons that never disappear
- Safe & Durable by design — sandboxed desktop renderer, in-browser SQLite with IndexedDB persistence, SQLite WAL on Android, and strict path containment
- Modern native audio & camera — HTML5 Canvas snapshot feed, WebM Opus audio recording, and native system share sheet integration
- Trustworthy codebase — all renderer files in strict TypeScript, 209 unit tests passing, automated E2E smoke tests, and CI hygiene guards
- Reliable releases — multi-platform desktop packages, Android APK/AAB, and instant web app with SHA256 checksums
