AI

Lucas AI for real expenses

Upload receipts, vouchers or statements; you can also type naturally. The backend extracts amount, currency, merchant, date, category and duplicates before you save.

Premium

Recurring payments with groups

Monthly calendar, pending charges, bills, subscriptions and groups like Personal, Family or Work. Payments can be marked, paid and filtered by type or group.

  • Accounts and activity

    Debit, credit, cash, savings, wallets and investment accounts. Balances, available credit, timeline, filters and detail stay inside the main shell.

  • Multi-currency transfers

    Full ISO 4217 catalog, cross-currency transfers and editable exchange rates. The backend derives each side from the source and destination accounts.

  • Loans with full schedule

    Daily, weekly, monthly or annual installments, interest, late fees, partial payments, reversals and debt progress in a compact view.

  • Investments with EOD prices

    Premium portfolio for stocks and ETFs: cash, buys, sells, positions, activity, safe logos and backend-cached closing prices.

  • Recoverable trash

    Archived accounts, transactions, transfers and investment activity have user-scoped restore and permanent delete routes.

  • Security without theater

    Passkeys, 2FA, secure refresh, request IDs, rate limits and stable JSON errors. Everything stays isolated by user.

How it works

From loose expense to complete system

A short flow to capture, review and keep your financial snapshot current.

    Create your accounts

    Add cards, banks, cash, wallets or broker accounts. Every account has currency, color, type and clear rules.

  2. 2 Step 2

    Record activity

    Use quick forms, transfers or Lucas AI with a photo, voucher, statement or short text.

  3. 3 Step 3

    Review before saving

    The app proposes amount, merchant, date, account and category. You confirm, edit or exclude duplicates.

  4. 4 Step 4

    Watch the system live

    Balances, timeline, stats, recurring payments, loans, investments and trash stay synchronized.

FAQ

What you're probably going to ask

When can I use LucasApp?

The KMP mobile app for iOS and the web version are being polished. We'll announce the launch date on X (@StevenACZ) and here at lucasapp.app.

Do I need a card for the Free plan?

No. Free is free to start and does not need a card. Premium only activates when you choose to go through checkout.

Is my data safe?

LucasApp uses passkeys, TOTP 2FA, secure refresh, rate limits and user isolation. Your data lives in your account and is never mixed with other users.

Is Lucas AI a general chat?

No. The backend is finance-only: AI reads receipts, vouchers, financial text, categories, dates, currencies and insights. The general chat surface was retired.

Which currencies are supported?

Full support for the 154+ ISO 4217 currencies. USD, PEN, EUR, COP and MXN sit at the top of the picker, but you can move money between any pair.

Can I cancel Premium?

Yes. Cancellation is handled from the Lucas plan flow when the subscription is active. You keep Premium until the end of the period already paid.
