Build Your Own Money App For Free
Monarch charges a hundred bucks a year to show you your own money. I rebuilt it for free in one night with Claude Code, and mine caught $150 in subscriptions I'd forgotten about.
Ryan FrizellePublished Jun 12, 2026What you'll walk away with
- The prompt that turns your bank exports into a real dashboard
- A daily refresh that runs itself, for free
- Every forgotten subscription pulled out of your own transactions
Every number these apps charge you for is already yours, sitting in a file you can download from your bank in about two minutes.
What you are building
Here is what you will do:
- 1Download your transactions from your bank as a CSV file, which is just a simple spreadsheet export.
- 2Drop those files in a folder and point Claude Code at them.
- 3Run one prompt and get a finance dashboard that updates itself every morning.
The prompt that builds it
I want you to build me a personal finance dashboard from my own bank data. I am not a developer, so explain anything you need from me in plain English.
I dropped my transaction history into this folder as CSV files I exported from my bank and credit cards. Read all of them.
Build me a single dashboard I can open in my browser that shows:
1. My net worth and how it changed this month
2. Where my money actually went, grouped by category
3. My runway: how many months I could survive on savings if my income stopped tomorrow
4. Every recurring charge and subscription you can find, so I can catch ones I forgot about
Make it clean and easy to read on my phone and my laptop. If a category is unclear, ask me instead of guessing. When it is done, tell me exactly how to open it.The Claude Code Course

What you get back
That one prompt reads every transaction you exported and turns it into a real dashboard. You get your net worth, where your money actually went, and a list of every subscription quietly draining your account.
Get your bank data out
Here is the one bit of setup before you run it:
- 1Log into your bank and credit card sites, find your transactions, and download them as CSV. Look for an Export or Download button near your transaction list.
- 2Make a new folder on your computer and drop every CSV file into it.
- 3Open Claude Code in that folder, paste the prompt, and let it build.
Make it update itself
Now make this dashboard update on its own every morning before I wake up.
Set it up so that each day it re-reads any new transactions in this folder and refreshes the dashboard automatically, with nothing for me to click. Walk me through any one-time setup on my computer step by step, in plain English, and keep the whole thing free. When I need to drop in a fresh export from my bank, tell me exactly where to put it.What you just replaced
That is the whole thing. Export your transactions. Drop them in a folder. Run the prompt. You just replaced a paid app with one that fits your life exactly, and it costs you nothing every month from here on.
