Hacobian — a private finance app built for one family.

A single-household personal finance app built for two co-owners. Dashboard, budgeting, transaction tracker, debts, subscriptions, and an AI advisor trained on their actual spending patterns. No generic template, no Mint clone — a tool built specifically for their accounts.

React 18 as a single-file PWA (2,800 lines, no build step), Netlify hosting, Supabase for database and auth, Anthropic API proxied through a Netlify function for the AI advisor. Eight pages. Bottom nav for mobile. Safe-area insets. Offline-first.

Two people, one source of truth. Every dollar tracked across shared and individual accounts. The AI advisor flags subscription creep, suggests debt-paydown ordering, and answers 'can we afford this?' questions in plain English.
