Tom Riddle

A magical AI-powered diary that listens, remembers, and reflects like Tom Riddle’s diary (Harry Potter), but kind, mindful, and truly personal.

🪄 Inspiration

The inspiration for this project came from the Tom Riddle Diary in the Harry Potter series — a mysterious, magical diary that interacts with its writer.
We wanted to recreate that immersive experience but with a positive twist: a personal, intelligent, and interactive diary that not only listens but remembers, reflects, and grows with you.

📓 What It Does

This is not just a digital diary — it’s a living memory.
Users can type a thought, a summary of their day, or just talk about how they’re feeling. The input disappears like a whispered secret, and the AI responds in an empathetic and intelligent manner, making the experience feel like a private, mindful conversation.

✨ Key Features

  • 🧠 Natural conversation interface with memory
  • 📅 Query past entries based on date
  • 🪞 Reflect on how you’ve changed over time
  • 📊 Personal dashboard with daily summaries
  • ✅ Optional checkboxes to track gym, study, and music habits

🏗️ How We Built It

The project is built using a modern stack of technologies:

  • Frontend: React.js, styled with CSS and HTML
  • Backend: FastAPI, FastMCB
  • AI Integration: Google GenAI, PyTorch models
  • Database & Memory: ChromaDB for semantic search and memory retention

🧱 Challenges We Ran Into

  • Designing an interface that feels magical yet practical
  • Making the disappearing input smooth and intuitive
  • Managing long-term memory efficiently while maintaining fast response times
  • Ensuring the diary AI balances understanding with concise communication
