What they did
Can a bot build a money tool that fits your situation? Instead of settling for a generic online calculator, he had Meta Muse build a retirement calculator and planner around his actual finances and goals. He can change the numbers to see how things play out over time, and he saved it to his phone's home screen to use like a regular app.
How it went
A personal retirement calculator you can tweak from your phone.
Worth knowing
- One user's Reddit post, no figures shared. A homemade calculator is only as good as its assumptions, so check the math and get a second opinion before big decisions. Don't put account logins into it.
Prompt
Cleaned version rewritten from the source — not a direct quote.
Build me a simple private retirement planner as a web page I can save to my phone's home screen. Inputs I can change: current age, retirement age, savings by account type [401k, IRA, taxable], monthly contributions, expected return, inflation, Social Security estimate and yearly spending in retirement. Show a year-by-year chart and the age the money would run out, if it does. Keep my numbers on my device only, and explain every formula in plain words so I can check it.
