Overview

AI expense tracker with automatic categorization, category budgets, spending insights and a daily safe-to-spend figure.

The story

Financial Copilot (ExpenseSink) is an AI expense tracker. Log an expense and it gets categorized automatically, counted against its category budget and folded into dashboards and AI spending insights.

It also works out a daily safe-to-spend figure and compares each week with the last, so a bad week shows up before the month is gone.

React 18 and TypeScript with Recharts on the front end; Supabase Edge Functions (Deno), Postgres and Supabase Auth behind it; deployed on Vercel.
