AI Expense Tracker is a modern and intelligent platform that allows users to track their expenses efficiently using an intuitive UI and smart features like AI-based categorization. Designed for individuals and professionals, this app helps users make informed financial decisions through real-time insights, seamless account management, and personalized dashboards.
Managing finances manually can be tedious. I wanted to build a smart, AI-powered app that automates categorization, simplifies tracking, and provides a beautiful user experience — helping everyone focus on how they spend, not how to track it.
