Budget-Inbox
Your bank shows $200.
Your budget shows every item.
Automatically sync Amazon orders to YNAB as itemized split transactions. Built for real YNAB users who are tired of manual data entry.
The Problem
You check your bank: "Amazon - $247.83"
But what did you actually buy?
Your bank has no idea. It's just a lump sum. Meanwhile, your email has the full order confirmation with every item, every price, everything that actually happened.
You love YNAB. You want to track groceries separate from household items separate from electronics. But manually entering 15 items from that email? 15 minutes you'll never get back.

Connect once. Shop normally. Your YNAB budget fills itself in with perfect itemized transactions.

The Vision
Email captures what really happened. Your bank just shows a lump sum.
Budget-Inbox started with Amazon because it's a real problem for real YNAB users (like me). But the same pattern exists everywhere.
More Retailers
Target, Walmart, Costco, Instacart—anywhere you get a detailed email receipt but a lump sum bank transaction.
Learning AI
Claude learns from your corrections and gets better at matching your budget categories over time.

Other Platforms
