How I Built a Smart Daily Planner Using Kiro in a Day

When I first joined the Code with Kiro Hackathon, I wanted to build something small, fast, and useful. I settled on a daily planner app — something anyone can use to track tasks in a clean, responsive layout. What made this project different was using Kiro, an AI-powered IDE, as my development partner.

Getting Started with Kiro

I started with a basic idea:

“Build a to-do list app that lets users enter tasks, view them, and delete or mark them as done.”

From that alone, Kiro helped me define the specs for the components I needed:
• A TaskInputForm
• A TaskListRenderer
• Individual TaskCards with complete/delete buttons

Using spec-driven development, I quickly got a solid project structure. Kiro also generated my class setup and even handled tricky logic like date-based filtering and localStorage handling.

Best Moment with Kiro

One of my favorite moments was asking Kiro:

“How should I store tasks so they reset daily?”

It immediately suggested storing tasks under date-based keys in localStorage, and even generated the function to handle that. It saved me hours.

Adding Agent Hooks

To make it smarter, I created a simple Kiro hook that checks if the day has changed and clears the task list if needed. Another hook re-sorts tasks whenever one is added or deleted. These hooks made the app feel polished without any complexity on my end.

Final Thoughts

This was my first time building something spec-first with an AI IDE, and honestly, I’m hooked. Kiro helped me think through architecture, generate quality code, and focus on features — not boilerplate.

Thanks to the Kiro team and Devpost for a great hackathon experience!
