Expense Expert - Project Documentation

Inspiration

We were inspired by the potential of modern AI to transform personal finance management. Traditional expense trackers often require manual categorization - we aimed to create AI-powered financial clarity that automatically derives insights from raw spending data. We scoured the internet for a good expense tracker which turns messy paper sheets into beautiful visuals with AI insights into your expenditures, but we were not able to find any. In this era of inflation, being financially smart is a necessity which is where our service comes in.

Natural Language Queries: "Show food spending under $50 last month" using Gemini NLP in the chatbot assistant
