I built a Chrome extension that interrupts you at checkout and asks "do you actually need this?" - would love feedback!
Hey everyone! I've been working on this for a while and finally launched it today, so excited (and a little nervous) to share it here.
It's called Mull — a free Chrome extension that sits on 40+ shopping and travel sites. When you're about to check out and click add to cart, a popup appears, gently pauses you and connects the purchase to a financial goal you're saving toward. You get three options: skip it and save the money toward your goal, "mull it over" (get a reminder in 24 hours), or just go ahead and buy — no guilt, no lockout, totally your call.
You can track multiple goals at once, star one as your current "Focus," build up a little savings pool from the purchases you skip, and if you want to go deeper, there's an optional budget layer that shows you a guilt-free spending number (income − needs − what you're putting toward goals).
I know "free browser extension" can set off scam alarms, so I want to be upfront: Mull runs 100% on your device. No server, no account, no login — your goals and spending never leave your browser, because there's nowhere for them to go. It only reads the product name and price on the checkout page so it can show you the reminder, and that's it. It's on the official Chrome Web Store, not a sideloaded file, so it's passed Google's review.
No affiliate links and no monetization right now — I'm just trying to build something useful before I ever think about revenue. And if it's not for you, uninstalling takes two seconds.2
