Built an expense tracking agent that takes a photo of a receipt and extracts merchant, line items, totals, and date, then categorizes based on your past spending habits. It also flags prices as good, bad, or fair.

Stack is Next.js 15, Supabase, Reducto for document parsing, and Subconscious for agent orchestration. The actual integration between the two is around 100 lines of code.

Wanted to see what a practical AI agent looks like as a real product rather than a chatbot wrapper. Open to feedback on the agent architecture especially.
