Every trip, flat, and dinner ends with "I'll split it later." Splitwise works, but it asks every friend to install another app, create an account, and rebuild a group that already exists in their chat. Half the group never joins, so the ledger is never complete.
Split is a working prototype of splitting as a tab inside a messenger, with no new app and no sign-up. Your phone number is your identity. Type "dinner was 120, I paid" and a split card lands on everyone's phone, showing each share before anything is saved. Snap a bill and everyone taps what they had, live. The Expenses tab covers what Splitwise users expect: equal, exact, percentage and share splits, several payers, edit and delete, history, and settle-up in the fewest payments. One tap on "Find expenses in this chat" reads a whole trip's history (1,000+ messages, bill photos and voice notes) and rebuilds the ledger with a citation for every result. It also imports real WhatsApp chat exports.
The model only reads; code does every calculation and checks every amount against its source message. It's a concept prototype, not affiliated with WhatsApp.
