Inspiration

As self-taught coders, we often wished for a friendly guide, someone to nudge us in the right direction without overwhelming us. That’s where WhatTheCode began. I wanted to create an AI-powered coding tutor that helps beginners learn easily and in a fun, gamified way.

What it does

WhatTheCode.xyz is a playful and powerful AI coding tutor. Powered by our assistant Cody, it helps users:

Learn coding concepts through interactive modules
Get real-time hints when stuck
Submit mini challenges and receive feedback
Stay motivated with progress tracking and challenge streaks

It’s like having a coding buddy who never sleeps (and doesn’t judge your typos).

How I built it

I built WhatTheCode using Bolt. And Bolt used React and Tailwind CSS to develop it. I have also used Gemini Flash 1.5 API to power our AI coding friend, Cody.

Challenges I ran into

Building a working MVP within the hackathon timeline. I started late, exactly 5 days ago, plus this was my first hackathon.
I was using AI in a project for the first time

Accomplishments that I'm proud of

Created a fully functional AI tutor that can answer questions and check code submissions
Designed a friendly onboarding experience
Developed a clean, modular frontend with protected routes and auth

What I earned

How to code a project without actually coding it. Thanks Bolt :)
How to use the Gemini API in the project (this was my first time).
Handling Supabase auth and database operations within React
That building a learning tool is just as much about emotion as it is about code
