Does the shopping legwork: tell it what you want, your budget and when you need it, and it searches across stores, compares price, reviews, sizing and delivery, and gives you two or three solid options with reasons. For list shopping (school supplies, moving, camping) it picks each item and gives you the links and the total. If you want things added to a cart, it does that on your connected computer, and checkout and payment are left to you. What you bought and the order details go into your knowledge base, so returns and warranties are easy later.

• Find me a dress for a summer wedding, size M, under $150, that arrives by Friday.
• Pick out everything on the school supply list in my Gmail on Amazon, then send me the links and the total. I'll place the order.
• I'm celebrating Diwali at a coworker's home next weekend. What customs should I know and what's a good gift? Pick one under $50 that arrives by Friday and send me the link.

Add it, then pick one to start its chat with.

Connect these when it asks. It works without them too.
