## What rectangle does

rectangle is a web application where users chat with an AI to find any real, physical product — electronics, apparel, home goods, appliances, toys, tools, beauty, pet supplies, and more. The AI understands product queries, searches across retailers in real time, and presents aggregated results. Users add items from multiple stores into one unified cart and pay once through Stripe. rectangle then places the individual store orders on the user's behalf automatically.

Key capabilities:
- **Conversational product search**: Describe what you want in plain language ("best 4K TV under $800", "mechanical keyboard with linear switches", "black running shoes under $150", "mid-century nightstand") and the AI finds matching products.
- **Multi-store price comparison**: Searches Amazon, Best Buy, Newegg, Walmart, Canada Computers, Staples, Target, and GameStop simultaneously.
- **Unified cart & single checkout**: Items from different stores go into one cart. One Stripe payment covers all of them.
- **Automated order fulfillment**: rectangle places orders at each retailer after checkout — users don't need accounts at individual stores.
- **PC Builder Studio**: Step-by-step custom PC builder with compatibility guidance for CPU, GPU, motherboard, RAM, storage, case, and power supply.
