Show HN: BankToBudget – Instantly turn your bank exports into a monthly budget

[arondeparon]

I built a small tool that turns any bank export (CSV, Qif, etc.) into a clear monthly budget summary.

https://banktobudget.com

It automatically detects:

- recurring income and expenses - variable costs (like groceries, parking, etc.)

No account, no subscription.

I use GPT-5 under the hood to interpret messy transaction data and group it intelligently — it works across banks and languages.

Would love feedback on:

- accuracy of the categories - clarity of the results - features you’d expect

The backend uses Laravel to parse and clean raw exports before sending structured data to GPT-5 for categorization. Nothing fancy; just a pragmatic way to turn raw bank data into something understandable.
