Keeva: AI-Powered Note-Taking Platform

This project involved architecting a complete SaaS product from the ground up, focusing on the intersection of knowledge management and artificial intelligence. The application provides users with a rich-text editing environment where they can organize information. The technical challenge was to integrate AI models that could analyze user notes in real-time to generate educational materials like summaries, flashcards, and quizzes.

For the monetization layer, Paddle was integrated to handle global payments, taxes, and multi-tiered subscription logic. This required building a robust webhook system to synchronize subscription status with the Supabase backend. The frontend, hosted on Vercel, was optimized for speed and reliability, ensuring that users have a seamless experience regardless of their geographical location.

Technical highlights of the SaaS platform include:

• Custom plugins for CKEditor 5 to support semantic formatting and AI-assisted drafting.

• Real-time data synchronization across devices using Supabase's real-time capabilities.

• Automated billing workflows and user lifecycle management through external payment provider integrations.
