I built something I think is useful with Claude Code. It's called Stack Buddy. I don't think it's AI slop, at least I hope not. Link below if you want to check it out.
Here's the back story on it...
I'm starting a new business this year and working 6-7 days a week in what feels like two jobs. I feel like 2026 through 2028 will be an interesting window for two things: using AI to build leverage in my small business, and stacking sats while we're still well below the Power Law trendline.
Stack Buddy is the calculator I wanted for myself to see if I worked my face off, how much I could stack in this period. So I built in between sessions with Claude Code and Codex
The first thing it does is simple: You put in your income, your tax rate, your monthly expenses, and what you're trying to save in fiat, and it tells you how much BTC you can realistically buy each month. Rough numbers are fine.
The second thing is more interesting.
You put in a target stack and a deadline, and it shows you three different paths to get there.
- Flat monthly DCA
- Front-loading heavier early when the price is below trend
- A custom mix of DCA and smash buys.
For the third scenario, you might do 2x your normal DCA on January 1 and July 1 each year, plus a tax-refund buy each April.
The math anchor is what I'm calling the "Catch-Up Power Law." The price today is well below the Power Law trendline, and the question is when we get back to it.
For the price model I ran that question through several AIs looking for the most defensible price guess, and June 30, 2028 came back as the answer with the strongest justification. Obviously I'd hold that date loosely but the calculator needs a concrete anchor and that's the one I'm using.
The model lets you see what your plan looks like under that assumption and stress-test how sensitive your stack is to the timing.
A few things worth knowing before you click through...
-
It runs entirely in your browser, doesn't call any LLM, doesn't store your numbers anywhere, and there's no account system.
-
The whole thing is open source on GitHub, and there's a download button at the bottom of the app if you want to grab the code, fork it, or run it yourself in Claude Code or Codex.
-
And maybe the coolest part, is there's also a prompt you can download and paste into a privacy-respecting LLM like
, Venice.ai, or you can wire up
API if you want to talk through your plan with an AI rather than just clicking buttons.
I'd love to know what you think and if you have suggestions on improvements I'd love to hear them.
