Tracking expenses is one of those tasks that everyone knows they should do, but few do consistently. Receipts pile up, transactions go unrecorded, and at the end of the month you're left guessing where your money went. What if you could simply snap a photo of any receipt and have AI handle everything else?

The Problem with Traditional Expense Tracking

Manual expense tracking fails for three reasons: it requires discipline (remembering to log every transaction), it requires time (typing amounts, categories, dates), and it requires consistency (using the same format every time). Most people start strong and abandon it within weeks.

What We're Building

This module covers two interconnected workflows that together create a complete financial tracking system:

  1. Invoice Capture Pipeline — Send a receipt photo to Telegram → Gemini AI extracts transaction data → saves to Notion database
  2. Reporting Pipeline — Weekly schedule trigger → pull recent transactions from Notion → AI generates summary → QuickChart creates visual chart → sends report back to Telegram
