Rectangle Shopping + Kits

Rectangle is an AI shopping agent tool that helps online shoppers compare products across hundreds of retailers, consolidate purchases into a single cart, and complete checkout automatically without opening multiple tabs. The tool accepts natural-language queries — you describe what you want, and Rectangle searches across retailers simultaneously, returning results ranked by value. Once you decide, Rectangle places orders at each retailer on your behalf and then tracks all shipments in one unified view until everything is delivered. Kits extends this by answering the question "what should I buy?" for a given activity or workflow: you pick a kit (such as a home office setup or a gaming rig), and Rectangle fills each slot with compatible, well-matched product picks. Rectangle covers a wide range of product categories including laptops, GPUs, appliances, books, coffee machines, and power tools. The tool is positioned as a universal shopping agent for consumers who want value-ranked results from many stores without the friction of juggling multiple browser tabs or separate checkouts. A "Try it free" entry point is shown on the homepage, indicating at least a free tier or free trial is available, though specific paid plan details are not disclosed on the site. Shoppers who frequently compare prices across Amazon, Best Buy, and similar retailers, or who need help building a compatible kit of products for a project, are the primary audience.

Online shoppers who want to compare prices across hundreds of retailers, build compatible product kits, and check out across multiple stores in a single automated flow.
