Inspiration

Rent, tuition, and groceries in Montréal keep climbing, and most student budget tools feel like homework. We wanted a tracker that feels like a game: quick, visual, and rewarding, so staying on budget is something you want to open.

What it does

WalletWize projects a student’s cost of living for a target year and breaks it down by categories (food now; housing/transport/school next). It turns historical CPI into a simple forecast and shows the impact on monthly spend so users can plan ahead.

How we built it

  • Data & model: Historical CPI (StatsCan), yearly index normalization, and a short-horizon CAGR forecast.
  • Backend: Python + Flask endpoints that return projected indices and costs.
  • Frontend: React (Vite) UI with a lightweight dashboard; Firebase for quick auth/storage.
  • Flow: User selects a year → API returns projected indices → UI renders monthly cost estimates.

Challenges we ran into

  • Integrating the frontend and backend
  • Learning full-stack development overnight

Accomplishments that we're proud of

  • We were able to build a great framework for a potential project and design a UI
  • Building multiple models to predict different areas of pricing

What we learned

  • Learning Git, React, and Flask in limited time
  • Creating a clean UI
  • Using Google APIs and fonts

What's next for WalletWize

In the future, we plan to expand WalletWize in three stages:

  • Short term: expand dataset, refine predictions for local Montreal users
  • Medium term: expand more to more cities and add more personalized expense categories;
  • Long term: transform WalletWize into an intelligent personalized financial assistant for every student, adapting automatically to your city, your lifestyle, and your data.
