🪙 LEDGR: AI-Powered Expense Tracker | Email-to-Expense Magic with Postmark & Gemini AI

LEDGR is an AI-powered expense tracking application that automates manual expense entry by forwarding receipt emails to a dedicated address. Postmark's inbound parsing and Google Gemini AI extract vendor name, amount, date, and category from the emails. The system sends smart budget alerts to users when they overspend. The demo is available at ledger-mu.vercel.app with test credentials or users can sign up. The application's architecture flow involves email receipt, Postmark inbound webhook, server function, AI processing, user-specific database, dashboard. The code is available on GitHub. The project was built using React, Supabase, Google Gemini AI, Postmark, and Vercel. The implementation involved setting up Postmark inbound, AI-powered data extraction, user-specific security, and smart budget alerts. The project's key learnings include Postmark's reliability, the power of email-driven applications, and the importance of building fallback features.
