SpendSense is a full-stack expense tracking web app built with React and Node.js. Users can add, filter, and manage their daily expenses while visualizing spending patterns through interactive pie and bar charts. The app includes a smart monthly budget tracker that alerts users when they're close to or over their limit.
The standout feature is the AI Financial Advisor — powered by Groq's LLaMA 3.3 model — which analyzes a user's spending data and generates personalized, actionable financial insights and saving tips in real time.
The project uses a secure Express backend proxy to keep API keys safe, localStorage for fast data persistence, and Recharts for clean, responsive data visualization. It's fully responsive and works smoothly across desktop and mobile.
Future Enhancements
- Deploy backend separately for full live AI functionality
- Add user authentication and cloud data sync
- Export expense reports as PDF/CSV
- Add recurring expense tracking
Known Issues
AI Insights feature requires running the local Express backend server (server.js); it will not work directly on the deployed Vercel link unless the backend is also deployed separately.
