Timely - AI Calendar Assistant

Traditional calendar applications require users to navigate complex interfaces and fill out multiple form fields for simple scheduling tasks. Users wanted a more intuitive way to manage their schedules through natural conversation, similar to how they would ask a human assistant. Existing solutions lacked the seamless integration between AI conversation and actual calendar functionality.

Built a comprehensive AI calendar assistant that interprets natural language requests and automatically creates calendar events through Google Calendar API integration. Implemented hot-swappable AI models (GPT-4 and Gemini) with real-time chat functionality, user authentication via NextAuth, and cross-device data persistence using MongoDB. The system features intelligent time parsing, context-aware event creation, and a fully responsive interface with smooth animations.

Developing this project in just 24 hours taught me the importance of rapid prototyping and MVP-focused development. Working with multiple AI models simultaneously highlighted the benefits of abstraction and modular architecture. The tight deadline forced creative problem-solving around API integration and state management. I gained valuable experience in OAuth2.0 flows and learned how to effectively combine multiple complex services (AI, Calendar, Database) into a cohesive user experience. Future iterations would include smart scheduling suggestions and conflict detection.
