PayPal AI Hackathon 2026

Roommates don't fight about money.
They fight about invisible labor.

The mental load of remembering bills, buying toilet paper, and managing utilities usually falls on one person. Traditional expense apps require manual entry, meaning the burden stays hidden and resentment builds. FairShare is a continuous settlement engine that quantifies the invisible and settles the debt in real-time via PayPal. We replace nagging with math.

The Invisible Burden

One roommate buys the toilet paper, remembers the water bill, and cleans the kitchen. The math is hidden, so the person doing the labor absorbs the cost and the resentment.

Zero-Friction Data

If logging takes more than 5 seconds, it won't happen. We ingest continuous IoT smart-plug usage, parse paper bills with AI, and use 1-tap buttons for mental load.

Executed Settlement

Insight without action is useless. The Fairness Ledger shows the math, and then fires off real PayPal Invoices for those who owe, and real PayPal Payouts to reimburse those who overpaid.
