I have fallen down the rabbit hole of comparing coffee makers across forty open tabs more times than I want to admit. All four AI tools now help with exactly this: remembering what you already ruled out, pulling live prices, tracking a price drop, or lining two options up side by side. Here is one feature from each, worth trying the next time you are staring down a real purchase.
Claude: memory
Claude can now remember details across your chats instead of starting from zero every time. It is rolling out on free, Pro, and Max plans right now (Team and Enterprise still use an older version).
- Go to Settings, then Memory, and turn on “Generate memory from chats.”
- Tell Claude your budget, must-haves, and what you have already ruled out while you compare options.
- Open a new chat later and ask it to pick up where you left off. It uses what it remembers instead of making you repeat yourself.
- Check Settings, Memory any time to see what it has stored, and edit or delete anything that is wrong or too personal.
When to reach for it: reach for this when a purchase decision takes more than one sitting, a mattress, a car, a big appliance, and you do not want to re-explain your budget and preferences every time you come back to it.

ChatGPT: search
ChatGPT can search the live web and show you sources, so you are not stuck with old information when prices change daily. It works on the free plan, even logged out.
- Ask your question normally, like “compare prices on a Ninja and a Cuisinart drip coffee maker.” ChatGPT searches the web on its own when a question calls for current information.
- Or trigger it yourself: open the tools menu, or type / and choose Search, to force a live web search.
- Read the inline citations and open the Sources panel to check where each price or claim came from.
- Ask a follow-up to narrow it, like “which of these ships free and has the better return policy.”
When to reach for it: reach for this when you want current prices or availability, not a features summary another tool already gave you from memory.

Copilot: copilot Shopping
The free consumer Copilot at copilot.microsoft.com has a shopping mode built for exactly this: product cards side by side, with pricing and reviews, and price tracking over time. As of now it is available in English to U.S. users, on the web and on mobile.
- Go to copilot.microsoft.com, or the Copilot app, and ask a shopping question, like “help me find a good drip coffee maker under $80.”
- Scroll through the product cards. Each shows a photo, price, store, and rating.
- Select “View Details” on anything promising for more options, sizes, stores, and a price history chart.
- Select the alert icon to track a price. Set your target, like 20% off, and how long to watch it.
When to reach for it: reach for this when you want to track a price over time instead of checking it once, and you are comfortable buying through the linked store. Double check the final price and terms on the retailer’s own site before you pay.

Gemini: shopping help
Gemini can pull from Google’s Shopping Graph to compare products side by side instead of describing them one at a time. You need a personal Google account (not work or school), 18 or older, with Keep Activity turned on, in one of a handful of supported countries including the U.S.
- Go to gemini.google.com, the Gemini app, or Gemini in Chrome, and describe what you are shopping for.
- When results come back, tap “Add” on each item you want to compare. They get pinned as attachments.
- Ask a follow-up, like “compare the basic specs and prices of these,” and Gemini lays them out side by side.
- Keep narrowing with more questions, like “which of these has the best warranty,” until one option is clearly ahead.
When to reach for it: reach for this when you have narrowed it down to two or three real options and want them compared directly, instead of researched one at a time.
