FinAI: Expense Tracker

FinAI: Expense Tracker — your personal finance app with AI. Forget spreadsheets: track expenses and income, scan invoices, and understand your money by talking to the app like a financial advisor. Built for freelancers and small businesses that need to manage daily expenses and income.

📷 SCAN INVOICES WITH YOUR CAMERA
Take a photo of any invoice or receipt. The AI automatically extracts vendor, date, invoice number, total, tax base, VAT, tax ID, and products with prices. Supports expenses and income: paychecks, sales invoices, and receipts. No typing needed.

🤖 AI ASSISTANT
Powered by Gemini 3.6 Flash to track your expenses naturally. Say "I spent $20 on coffee" or "I got paid my salary" and it's recorded instantly. Ask "How much did I spend this month?" or "What's my balance?" and get the answer right away. The AI remembers the conversation context and suggests categories and subcategories automatically.
