Lumen AI answers the question that matters most to you every morning: How much can I spend today to make it last this month?
Using your income, fixed expenses, and what you've already spent, Lumen calculates your safe daily spending—the exact amount you can use today without compromising what you need until your next paycheck. Everything is recalculated instantly with each entry and with the countdown to your next pay period.
HOW TO TRACK YOUR EXPENSES
• Chat with Lumi: Write to her in natural language—"I spent 30 at the store"—and she'll categorize it and confirm it with you before saving.
• Voice dictation: Record an expense by speaking, without touching the screen.
• Receipt scanning: Take a photo, and Lumen extracts the amount and category.
• Manual entry: Unlimited, always available.
WHAT ELSE LUMEN DOES
• Fixed expenses: Automatically separates your monthly payments (rent, utilities, internet) so they never get mixed up with your day-to-day spending.
• Limits by category and savings goals, with reminders.
• Installment purchase simulator: Before agreeing to financing, compare how much you would end up paying with different rates and terms.
• Complete history, transaction editing, manual entries, and data export.
• Available in Spanish and English, with automatic language detection.
PRIVACY FIRST
Lumen AI doesn't connect to your bank or financial aggregators, and never asks for your bank passwords. It doesn't require an account or login: there's no server with your name anywhere. Your data is stored only in your device's private storage. If you uninstall the app, everything is permanently deleted—that's why there's no need to "close" an account.
Lumen AI is a personal financial organization tool. It's not a bank, an accounting service, or a financial advisory firm, and it doesn't make decisions for you: the calculations are estimates based on what you enter. Always double-check the amounts before saving.
Free plan: Includes 5 AI-enabled entries per month (chat, voice, and scanning share this limit), 2 spending limits, 1 goal, and 3 reminders, plus daily spending security, full history, editing, manual entries, fixed expenses, accounts, and unlimited export. Your existing entries are never locked.
