Rightal Notes
Rightal Notes is a modern, intelligent note-taking application that combines traditional note-taking with AI assistance and unique ephemeral notes (stories) that disappear after 24 hours. Built with Flutter for cross-platform compatibility, it offers offline-first functionality with cloud sync capabilities.

Challenges & Solutions
Challenge: Offline-First Architecture
Implementing a robust offline-first system that handles data conflicts and ensures seamless sync when connectivity is restored.
Solution:
Implemented Hive for local storage with conflict resolution algorithms and a queue system for pending sync operations.
Challenge: AI Integration with Privacy
Integrating AI features while maintaining user privacy and managing API costs effectively.
Solution:
Created a coin-based system with local API key management, allowing users to control their AI usage and costs while maintaining privacy.
Challenge: Ephemeral Notes Management
Designing a system for temporary notes that reliably expire after 24 hours across different app states.
Solution:
Implemented automatic cleanup services with database triggers and local cleanup routines that run on app startup and periodically.
