About me & PocketPilot

Hi, I'm Jaein.
I built PocketPilot.

I'm a high school student interested in computer science and financial education. Personal finance is often introduced through abstract rules, so I wanted to build something that lets teenagers learn by changing real numbers and immediately seeing the result. PocketPilot is my attempt to make budgeting feel less intimidating and help students build confidence before they begin making larger financial decisions on their own.

Two core features

PocketPilot connects a clear view of the current month with a forward-looking goal forecast. The first feature explains what is happening now; the second shows how today's choices can shape what happens next.

01
Budget AnalysisSee where one month goes
Income₩1.0M
Spending64%
Left₩210K

Enter monthly income, expenses, and investments. PocketPilot recalculates totals and saving rates instantly, visualizes the result with breakdown charts, and highlights the spending pattern that deserves attention first.

02
Goal SimulatorTurn a budget into a timeline
Laptop goal7 months
GOAL
58% saved42% invested

Choose a goal and split the available monthly amount between savings and investments. PocketPilot projects the balance month by month, applies simple or compound returns, and compares how risk assumptions change the estimated timeline.

AI feedback

PocketPilot combines a prepared financial-coaching prompt with a structured summary of the user's income, spending, saving capacity, goal, and investment risk. It sends this information to the ChatGPT API and returns a personalized explanation with one practical next step.
