// real transaction anomaly detection
PayPulse
Point PayPulse at your actual transactions — paste a bank CSV export, or connect your bank — and it flags double charges, amount spikes, new-merchant big spends, velocity bursts and more. Your data never leaves this session except to your bank via Plaid.
// paste csv or choose a .csv file
Needs date, description and amount columns (headers detected automatically). Export CSV from your bank's website — most banks offer it under statements/activity.
Heuristics flag patterns worth a human look — they are not fraud determinations. CSV data is processed in-memory per request and never stored. Plaid access tokens are held in server memory only; use encrypted per-user storage before production use.
