I kept making purchases I'd regret - then wondering what that money could've been if invested instead. So I built GrowIt. Install it once, and every product page shows you exactly that. $45 water bottle? $68K in 30 years. No setup. No account. Just the number you didn't have. Works on Amazon, IKEA, Walmart, Adidas & more. Free forever. Chrome, Firefox & Edge. Informed choices, not guilt trips.
I built GrowIt after one too many impulse purchases I regretted -
and a growing obsession with understanding what those purchases
actually cost me long-term.
The problem isn't that people don't care about their finances.
It's that the information isn't there at the moment it matters
most - when you're about to buy something.
GrowIt fixes that. It's a free browser extension that
automatically injects a small widget on any product page
showing you what that price could grow into if invested instead.
No setup. No account. No manual entry. It just appears.

How it works:
→ Install the extension (Chrome, Firefox, or Edge)
→ Browse normally - Amazon, IKEA, Walmart, Adidas, wherever
→ The widget appears automatically on product pages
→ See $45 → $68,000 in 30 years. Decide what you want to do.

What makes it different from every other finance tool:
- It meets you at the moment of purchase - not in a separate app
- Small purchases (under $100) show monthly habit math, not
just one-time cost - because a $18 Netflix sub is more
interesting as $27,000 over 30 years
- Large purchases show lump-sum investment value
- You can always toggle between both views
- Completely free, forever - no account, no tracking,
no ads inside the widget
- Bilingual EN/FR - built for the Canadian market

The philosophy: informed choices, not guilt trips.
GrowIt doesn't tell you not to buy. It gives you the one
piece of information you didn't have. You still decide.
Some people see the number and put the item back.
Some see it and buy anyway. Both are completely fine.
I built this solo as a side project that scratched my own itch.
Would love to hear what you think - brutal feedback welcome.
