You’re probably overpaying for everything you buy online. Not because you’re careless, but because it’s impossible to check every site.
The same product can vary 10–30% across retailers.
The internet made shopping convenient. It never made it optimal.
That’s why I built Rectangle. An AI shopping agent and researcher for tech & electronics:
- Ask anything about a product.
- Compare across hundreds of retailers.
- Add everything to one cart and check out once.
- Automatically track your warranties
No tab hopping. No guesswork. No multiple carts. No multiple checkouts.
I'd love for you to try it out for funzies or try buying a couple things you want, would love some feedback.
