How does auto-categorisation work?

On import, each transaction's merchant name is matched against a rules table (Whole Foods → Groceries, Uber → Transport, etc). Initial rules come from a starter set; the app learns from your manual recategorisations. AI-assisted categorisation is optional via a small OpenAI call per uncategorised transaction.

How does recurring subscription detection work?

The app groups transactions by merchant + amount and flags any merchant that charged the same amount on a monthly cadence for 3+ months. The "subscriptions" view lists them with annual cost. Useful for spotting Netflix, ChatGPT, that gym you cancelled but didn't.

Can I import from multiple bank accounts?

Yes. Each account has its own row, transactions reference an account_id. CSV import lets you specify which account on each upload. For automatic sync, use Plaid (US/CA), GoCardless / TrueLayer (EU/UK), or regional bank APIs.

Does it handle multi-currency?

Yes. Each transaction stores amount + currency. The app fetches FX rates daily via a free provider (exchangerate.host or similar) and converts to your base currency for chart display. Original amount preserved for accurate per-transaction view.

Why generate it instead of buying it.

“

YNAB is $99/year. Mint is dead. Most expense trackers force their categorisation rules and chart styles. Generate one that fits your actual categories and the way you think about money.

“

Personal financial data is sensitive. Owning the database means it sits in a region you choose, encrypted at rest, deleted on your terms. No vendor analyst sees your transactions.
