Show HN: I made a browser extension that exposes the hidden cost of shopping

1•pjcodes•1d ago
Hi again, HN. Three weeks ago, I showcased my impulse control PWA, "Nope It," here on HN. The discussion and feedback I received were incredible, and I'm hugely grateful to this community for it.

The single most valuable piece of feedback I got was about friction. Many of you rightly pointed out that in that critical 5 second window on a shopping page, the mental energy required to open a separate app is often too high. The impulse wins by default.

You were right. So, I spent the last couple of weeks building the solution.

Today, I’m launching Nope It for Chrome.

It's a lightweight browser extension that uses JavaScript and DOM manipulation to inject a "psychological speed bump" directly onto product pages (I'm starting with Amazon, as it's the biggest culprit for me).

The core of the extension is the real time "Work Hours Psychology" engine. It shows you that a $200 gadget doesn't just cost money, it costs you a full day of your life. When you see that, you can log the impulse with a single click without ever leaving the page. It then syncs everything back to the core PWA.

I'm back here because your initial feedback is what created this. My main question for the HN community is, Does this frictionless, point of sale approach feel like the right solution to the problem you helped me identify? I’d love your thoughts on the UX and the overall strategy.

You can grab the new extension from the Chrome Web Store here: https://chromewebstore.google.com/detail/nope-it/imamiekokcj...

The main PWA is still here: https://www.nopeit.app

Thanks for helping me build this.
