Ever wish you had a tutor that never got tired, remembered your mistakes, and explained things like you're five?

I built that. And I did it in a weekend—with GPT-4, some no-code tools, and a love for Python.

😩 The Problem

Learning to code can be lonely and overwhelming.

Videos are passive, courses lack personalization, and human tutors are expensive.

💡 The Idea

I wanted to build a GPT-powered AI tutor that:

  • Creates personalized quizzes 📋
  • Explains hard concepts in simple terms 🤓
  • Tracks my weak spots and brings them up later 🔁

Introducing Study Buddy — your new AI learning sidekick.

🛠️ The Stack

Tech Breakdown:

  • GPT-4 Turbo – Core reasoning engine for Q&A
  • LangChain – Prompt chaining and logic
  • Next.js + TailwindCSS – Clean, mobile-friendly UI
  • Supabase – Stores progress and quiz history
  • Framer Motion – Animations that make it feel alive
  • OpenAI Assistants API (optional) – Persistent chat experience

Bonus: Could easily become a Telegram bot, mobile app, or ChatGPT custom GPT.

🗓️ Build Timeline

🕐 Day 1:

  • Designed the learning flow
  • Created quiz and feedback logic using GPT-4
  • Pulled beginner Python topics from OpenAI
  • Wrote spaced repetition logic

🕑 Day 2:

  • Hooked up Supabase for user tracking
  • Built UI in Next.js with gamified XP system
  • Animated the quiz flow for a smoother experience
  • Tested with friends learning to code

✨ Key Features

  • 🧠 “Explain Like I’m 5” toggle
  • 📋 Daily quiz mode (5 questions / day)
  • 🎯 XP + streak tracker
  • 📊 Progress dashboard
  • 🔁 Smart repetition: GPT flags and repeats weak areas

🧪 Sample Prompt 

You are a study coach for beginners learning Python. Create a 5-question quiz focused on variables and data types. After each user answer, provide:
- A correct/incorrect check
- A one-sentence explanation
- A follow-up if the answer was wrong

✅ What to Do Next:

  • ✅ Add user login & dashboard
  • 🧠 Long-term memory with Assistants API
  • 🧪 Add more languages (JS, HTML, SQL, etc.)
  • 📱 Mobile app version
  • 🛍️ Launch a premium GPT or Notion-based study plan

🚀 Final Thoughts

This AI tutor didn’t just give me answers—it taught me how to think. If you’re building with AI, don’t just replicate Google. Make it personal. Make it smart.
