Rectangle is the first place where you can shop at multiple retailers like Amazon, Best Buy, Newegg, Walmart, and more. No switching tabs or losing track. We add AI on top: chat to find products, get recommendations, and use our Builder Studio to spec a full PC (CPU, GPU, RAM, etc.) with a budget and purpose in mind. Pick parts from live search results, add them to your build, and checkout once. One cart, one checkout. You decide, we execute.

Shopping for tech online is still surprisingly painful. You open a dozen tabs, compare prices across retailers, read reviews everywhere, watching youtube videos and still are not sure if you are getting the best deal or even buying the right thing. I ran into this constantly when buying tech and electronics, from PC parts to monitors, TVs, and speakers, so I decided to build something to fix it. Rectangle is an AI-powered shopping agent that lets you shop across multiple retailers in one cart and check out once. You can add items from Amazon, Best Buy, Newegg, Walmart, and more, compare prices and options in one place, and let rectangle handle the rest. The AI helps with discovery and comparisons without sending you across the internet. I also built Builder Studio for PC builders. You set a budget and purpose like gaming or workstation, get part recommendations from live inventory, and add the entire build at once. Rectangle is still an MVP and far from perfect, but I wanted to get it into people’s hands early. I would genuinely love feedback from this community.
