WhatsApp Expense Tracker: Text, Image & Audio Inputs

CashMate turns WhatsApp into a smart finance assistant that handles multi-input expense logging without apps or sign-ups. New users auto-register by sending 'Hi', creating a profile in your self-hosted PostgreSQL database. Every message is routed via AI intent classification into one of five branches: reports, natural-language transactions, receipt OCR, voice transcription, or general queries.

For transactions, describe expenses like 'Paid 200 to Mukesh for car repair'—AI extracts date, amount, category, and payee. Upload receipts for Gemini OCR to parse line items and auto-categorize. Voice notes are transcribed by Deepgram, then processed like text inputs. Request summaries like 'today's report' or 'May vs June' for instant income, expense, and balance insights directly in chat.

Ideal for freelancers, solopreneurs, small businesses, and busy professionals seeking zero-friction bookkeeping. Benefits include no app switching, privacy via self-hosted DB, elimination of manual entry, and on-demand analytics. Save hours weekly on tracking while gaining actionable financial overviews anytime.
