HackDelft 2026 - Revolut AI Challenge

Financial clarity,
illuminated.

Upload your bank statement and get instant categorization, spending analytics, and clean financial insights.

No credit card required - Works with CSV & PDF exports from 10+ banks

Features

Everything you need to understand your money

One-click import

Export from your bank, drop it in Lumen. Duplicates are detected automatically - import as often as you like.

Instant categorization

Rule-based categorization fires first - Albert Heijn > Groceries, OVpay > Transport. Every label is editable.

Spending analytics

Income vs expenses, category breakdown, net savings, and top merchants - all from a single view.

Period filters

Switch between week, month, quarter, year, and all-time. Charts adapt granularity automatically.

Private by design

Row-level security means your transactions are only visible to you - not even us.

PDF export

Generate a financial report with one click: summary totals, category breakdown, top merchants.
