Key insight: The friction isn't splitting bills — it's that people use receipt photos as proof but then manually re-enter data into generic split apps, creating a reconciliation gap that LLM parsing can eliminate entirely

The Problem

When friends or colleagues split bills, someone pays the full amount but multiple people owe different amounts based on what they ordered. Manual calculation of who owes whom is error-prone, and existing split apps force you to manually select items per person rather than reading the actual receipt data.

Target Audience

Roommates splitting rent/utilities, friend groups on group trips, small teams with shared project expenses, book clubs or activity groups with rotating hosts

Why Now?

Vision APIs and LLMs are now accurate enough to extract line items and prices from messy photos; group travel and shared housing are booming post-pandemic

What's Missing

Existing apps require manual item assignment per person; no tool connects actual receipt data to settlement calculations in one flow, forcing users to remember who ordered what
