The Challenge

Group trips often lead to financial confusion, awkward debt conversations, and lost receipts. Splitting expenses fairly across a dynamic group in real-time is a hard UX and data-sync problem.

Our Solution

  • Built an AI-powered chat interface that parses natural language like 'Raj paid ₹1200 for dinner' and automatically logs the expense.
  • Implemented real-time Firestore subcollections with offline support so expenses sync instantly across all group members.
  • Designed a smart ledger algorithm that minimises the number of transactions needed for the whole group to settle up.
