AI & Intelligent Systems

Smarter financial tracking with AI-powered insights and real-time advice.

A personal finance platform that combines expense tracking with dual AI insights — NestJS, Flutter, MongoDB, OpenAI, and Gemini — so users can parse bank statements, follow spending, and get contextual financial guidance.

Chapter 02
The challenge

Money tools were fragmented, static, and rarely personal.

Users juggled expense logging, bank statement reconciliation, and generic tips that never adapted to their real transactions or context.

01

No real-time transaction streams

Traditional apps missed SMS-based notifications and live spending updates.

02

Static dashboards

Charts showed history without predictive or contextual insight.

03

Generic financial advice

Tips ignored the user’s actual spending patterns and goals.

04

Tedious statement analysis

Bank PDF/CSV review and categorization was manual and error-prone.
