HackBuddy AI

An AI-powered hackathon copilot that helps hackers generate ideas, code, and documentation using Google Gemini.

Inspiration

As hackers and students, we often struggle with time, clarity, and documentation during hackathons. We wanted to build something that actually helps hackers while hacking — not after. HackBuddy AI was inspired by the idea of having an AI teammate that can instantly generate ideas, explain concepts, and help with documentation during a hackathon.

What it does

HackBuddy AI is a web-based AI assistant that helps hackers generate hackathon ideas, create README documentation, explain technologies, and suggest future improvements — all in real time using AI.

Users simply enter a prompt, and HackBuddy AI responds instantly with meaningful, structured output.

How we built it

We built HackBuddy AI using:

  • Frontend: HTML, CSS, and JavaScript for a clean and responsive UI
  • Backend: Python with Flask
  • AI: Google Gemini API (Gemini 2.5 Flash model)

The frontend sends user prompts to the Flask backend, which then calls the Gemini API and returns AI-generated responses to the UI.

Challenges we ran into

  • Integrating the updated Google Gemini API and resolving deprecated SDK issues
  • Fixing model compatibility errors (404 model not found)
  • Handling long AI responses so they display properly in the UI
  • Managing API keys securely while testing locally

Accomplishments that we're proud of

  • Successfully integrated Google Gemini API with a full-stack web app
  • Built a working AI assistant within hackathon constraints
  • Designed a clean and functional UI that works smoothly
  • Made the project beginner-friendly and useful for real hackers

What we learned

  • How to work with modern AI APIs and SDK changes
  • Full-stack integration between frontend and backend
  • Debugging real-world API and deployment issues
  • How to build a project focused on actual user value

What's next for HackBuddy AI

  • User authentication and chat history
  • More advanced prompt templates for hackers
  • Voice input/output using AI
  • Deployment on cloud platforms for public access
  • Team collaboration features for hackathons
