你是否曾有过这样的经历：在网上看到想买的东西，把它留在浏览器标签页里，然后完全忘了在哪里看到的？也许你在用谷歌搜索时看中了一副很棒的耳机，后来又在另一家零售商那里找到一件生日礼物。不知不觉间，你已经打开了十几个标签页，却不知道哪家店的优惠更好。
Ever find something you want to buy online, leave it sitting in a browser tab and then completely forget where you saw it? Maybe you spotted a great pair of headphones while searching Google. Later, you found a birthday gift at another retailer. Before long, you've got a dozen tabs open and no idea which store had the better deal.
谷歌认为自己有解决办法。10月15日，该公司开始在美国推出Universal Cart，这是一款由人工智能驱动的新购物工具，可将不同零售商的产品汇集到一处。它还能追踪价格、留意补货情况，并帮助你在结账前找到省钱的办法。
Google thinks it has a solution. On Oct. 15, the company began the U.S. rollout of Universal Cart, a new artificial intelligence-powered shopping tool that brings products from different retailers into one place. It also tracks prices, watches for restocks and helps you find savings before checkout.
随着假日购物季临近，这个时机可能特别有用。但还有一个值得一问的问题：把所有东西放进一个购物车，是会帮我们少花钱，还是只是让我们更容易多买东西？
With holiday shopping approaching, the timing could be especially useful. But there's another question worth asking. Will having everything in one cart help us spend less, or simply make it easier to buy more?
Google Universal Cart是一个购物中心，可在谷歌搜索和Gemini应用中使用。你不必再为可能购买的商品分别保存清单，而是可以把来自不同零售商的商品保存在一处。例如，你可能在谷歌搜索时找到一台咖啡机，并把它加入Universal Cart。之后，当你和Gemini讨论礼物创意时，你可以保存另一家商店的一双运动鞋。
Google Universal Cart is a shopping hub that works across Google Search and the Gemini app. Instead of keeping separate lists of products you might buy, you can save items from different retailers in one place. For example, you might find a coffee maker while searching Google and add it to your Universal Cart. Later, while talking with Gemini about gift ideas, you could save a pair of sneakers from another store.
当你回来时，这两件商品都会在那里等你。谷歌最早于2026年5月预览了这款工具。现在，Universal Cart正在向美国购物者推出。它使用谷歌的Shopping Graph，其中包含超过600亿条持续更新的商品信息。这些信息帮助系统监控受支持商品的价格和库存情况。
When you return, both products will be waiting for you. Google first previewed the tool in May 2026. Now, Universal Cart is rolling out to U.S. shoppers. It uses Google's Shopping Graph, which contains more than 60 billion continually refreshed product listings. That information helps the system monitor prices and availability across supported products.
这里最大的吸引力是便利。但谷歌还增加了几项功能，也可能帮助你避免支付超出必要的费用。
The biggest attraction here is convenience. But Google has added several features that could also help you avoid paying more than necessary.
网购常常意味着要在不同网站之间来回切换。你在塔吉特找到一件商品，在沃尔玛查看另一件，然后又去丝芙兰买礼物。记住每样东西是在哪里看到的会变成一件麻烦事。Universal Cart让你可以保存通过谷歌搜索和Gemini发现的支持商品。更重要的是，当你再次购物时，已保存的商品会保留在一起。当你要为几个人购物，或进行需要做些研究的较大额购买时，这会很方便。你可以把备选商品整理得井井有条，而不必马上决定购买。
Shopping online often means bouncing between websites. You find something at Target, check another item at Walmart and then head to Sephora for a gift. Remembering where you saw everything can become a chore. Universal Cart lets you save supported products you discover through Google Search and Gemini. More importantly, your saved items stay together when you return to shopping. That could come in handy when you're shopping for several people or making a big purchase that requires some research. You can keep your options organized without committing to buying anything right away.
下面这个功能我觉得特别有意思。Universal Cart可以监测已保存的商品，并在降价时通知你。当售罄的商品重新有货时，它也能提醒你。假设你在考虑买一台新电视，但还没准备好花这笔钱。与其每天早上都去同一家零售商那里查看，你可以把它保存下来，让谷歌的购物系统替你留意变化。随着黑色星期五和假日购物季临近，这些提醒可能尤其有用。不过要记住，降价并不自动保证那就是最低价。
Here's the feature I find particularly interesting. Universal Cart can monitor saved products and notify you when a price drops. It can also alert you when something that sold out becomes available again. Suppose you're considering a new television but aren't ready to spend the money. Rather than checking the same retailer every morning, you can save it and let Google's shopping system watch for changes. The alerts could be especially helpful heading into Black Friday and the holiday shopping season. Still, remember that a price reduction doesn't automatically guarantee the lowest price available.
这正是谷歌的人工智能开始额外发挥作用的地方。Universal Cart可以显示相关促销码，并考虑与你的支付卡相关的权益。比如说，你有多张信用卡，但记不清哪一张在某个特定零售商那里提供更好的返现。Universal Cart利用谷歌钱包中的信息来了解受支持的信用卡权益，并帮助你在不同支付方式之间做选择。它还可以直接在购物车里显示相关促销码，可能帮你找到原本会错过的优惠。
This is where Google's AI starts doing some extra work. Universal Cart can surface relevant promotional codes and consider benefits associated with your payment cards. Let's say you have multiple credit cards but can't remember which one offers better rewards at a particular retailer. Universal Cart uses information from Google Wallet to understand supported credit card benefits and help you choose between payment methods. It can also show relevant promotional codes directly in your cart, potentially helping you find savings you might otherwise miss.
不过，我在选择用哪张卡之前还是会先核对细节。返现和积分计划都有条件，积分最高的优惠未必总是最省钱。
However, I would still check the details before choosing a card. Rewards programs come with conditions, and the highest points offer may not always translate into the greatest savings.
一旦您准备好购买商品，Universal Cart 会为您提供更加便捷的结账体验（尤其是与那些支持该功能的零售商合作时）。在某些情况下，您可以直接通过 Google Pay 完成购物流程；或者，Google 会将您选中的商品信息传输到零售商的官方网站，让您在那里完成订单。目前支持该功能的零售商包括 Nike、Sephora、Target、Ulta Beauty、Walmart 和 Wayfair，以及许多使用 Shopify 平台的商家。
Once you're ready to buy, Universal Cart offers a more streamlined checkout experience with participating retailers. In some cases, you can complete the purchase using Google Pay directly from the cart. Alternatively, Google can transfer your selected items to the retailer's website so you can finish your order there. Google says its simplified checkout experiences include retailers such as Nike, Sephora, Target, Ulta Beauty, Walmart and Wayfair, along with many Shopify merchants.
不过，具体的结账选项会因零售商的不同而有所差异。无论如何，订单的确认及客户支持仍由相应的零售商负责——因此，如果您有配送或退货问题，需要直接联系相应的商家。
However, the available checkout options depend on the retailer. Either way, the retailer remains the seller of record and handles order confirmations and customer support. That means you'll continue dealing with the merchant for delivery questions or returns.
注意：有 119,000 家假冒网站可能窃取您的信用卡信息！Google 于 10 月 15 日开始在美国用户中推出 Universal Cart 功能。该功能可在 Google 搜索和 Gemini 应用中使用，不过随着推广的推进，具体可用性可能会发生变化。要体验该功能，请打开 Google 搜索或 Gemini 应用，查找您感兴趣的商品。当 Universal Cart 功能在您的购物流程中可用时，您可以保存来自不同零售商的商品信息；这些商品信息会在您下次访问时仍保留在购物车中，让您能够继续之前的购物流程。
119,000 FAKE SHOPS COULD STEAL YOUR CREDIT CARD DETAILS Google began rolling out Universal Cart to U.S. users on Oct. 15. The feature works across Google Search and the Gemini app, although availability may vary as the rollout continues. To explore it, open Google Search or Gemini and look for products you're interested in buying. When Universal Cart becomes available in your shopping experience, you can save supported products from different retailers. Google says those items will remain in your cart when you return, allowing you to pick up where you left off.
此外，您还可以通过该功能监控商品价格的变化、查看促销信息，并了解可用的结账方式。不过，Google 并未提供适用于所有设备的统一使用说明；这些功能的显示方式及位置可能会因设备类型而有所不同。
You can also use the cart to monitor price changes, discover promotional offers and review available checkout options. However, Google hasn't provided a single set of instructions that applies to every device. The appearance and placement of these features may vary.
不一定。谷歌表示，“Universal Cart”功能可以整合不同零售商的产品信息，但这并不意味着所有在线商店都支持该功能的全部功能；用户能够保存哪些商品，实际上取决于这些商店是否提供了相应的购物体验。此外，结账方式也因商家而异：有些商品可以直接通过 Google Pay 完成购买，而有些商品则需要用户在零售商的官方网站上完成交易。
Not necessarily. Google says Universal Cart can organize products across retailers, but that doesn't mean every online store supports every feature. The products you can save depend on supported shopping experiences. Meanwhile, checkout options vary depending on the merchant. Some purchases can happen through Google Pay in the cart, while others require you to finish on the retailer's website.
谷歌最初于 5 月推出了“Universal Cart”功能，并计划将其应用于搜索服务（Search）、Gemini、YouTube 和 Gmail 等平台；但在 10 月 15 日的官方公告中，仅确认了该功能在美国的搜索服务和 Gemini 平台上的可用性。至于该功能是否会在 Gmail 或 YouTube 上推出，谷歌尚未公布具体时间。
Google originally introduced Universal Cart in May with plans to bring it to Search, Gemini, YouTube and Gmail. However, its October 15 launch announcement specifically confirms availability across Search and Gemini in the U.S. Google has not announced a confirmed launch date for Universal Cart integration with Gmail or YouTube.
在技术层面，谷歌采用了名为“Universal Commerce Protocol”（简称 UCP）的通用技术标准。这一标准旨在帮助基于人工智能的购物工具与零售商及支付系统进行有效沟通。对于消费者而言，这些技术细节其实并不重要，真正重要的是该功能能够为他们带来哪些便利。UCP 功能让谷歌能够将产品搜索与结账流程无缝连接起来，从而减少了用户在多个购物平台之间切换的麻烦。
Behind the scenes, Google uses something called the Universal Commerce Protocol, or UCP. It's a shared technical standard designed to help AI-powered shopping tools communicate with retailers and payment systems. For shoppers, the technical details are less important than what they make possible. UCP helps Google connect product discovery with checkout, reducing the need to jump between different shopping experiences.
谷歌还在不断扩展其人工智能购物服务：例如，“Let Google Call”功能可以利用人工智能联系附近的商店并查询商品库存情况。亚马逊也在开发类似的人工智能购物工具，而 OpenAI 则提供了能够协助完成购物相关任务的智能助手。因此，争夺成为用户数字购物助手的竞争正在日益激烈。
Google has also been expanding AI shopping beyond the cart. Its Let Google Call feature, for example, can use AI to contact nearby stores and check product availability. Amazon has been developing AI-powered shopping tools, while OpenAI offers AI agents that can assist with shopping-related tasks. The competition to become your digital shopping assistant is heating up.
让谷歌帮你管理购物信息确实很方便，尤其是如果你已经在使用谷歌的搜索功能（Search）和 Gemini 人工智能工具的话。不过，你还是需要仔细考虑：你是否愿意将自己的购物信息存储在谷歌账户中。Universal Cart 功能会利用 Google Wallet 来识别可用的支付优惠和相关促销信息。不过，谷歌在发布该功能时的官方声明中并未详细说明这些购物数据会被保存多久，也不知道这些数据会如何被用于广告推广。
Having Google organize your shopping could be convenient, especially if you already use Search and Gemini. Still, it's worth considering how much shopping information you're comfortable keeping within your Google account. Universal Cart uses Google Wallet to help identify supported payment benefits and relevant offers. However, Google's launch announcement doesn't provide detailed information about how long Universal Cart shopping data is retained or exactly how it may be used for advertising.
在使用该功能之前，请务必查看你的谷歌账户隐私设置以及谷歌发布的隐私政策。建议不要想当然地认为将商品添加到 Universal Cart 中就意味着这些购物信息会被保密；如果你要为某个也使用你的谷歌账户的人购买礼物，那么在保存购物信息之前请三思。当然，常规的在线购物注意事项仍然适用：在完成购买前，请务必核对最终价格，并确认你购买的对象是正规商家。
Before relying on the feature, review your Google account's privacy settings and Google's published privacy policies. For now, I would avoid assuming that adding something to Universal Cart keeps that shopping interest private. And if you're buying a surprise gift for someone who shares access to your Google account, think twice before saving it there. Of course, the usual online shopping precautions still apply. Before completing a purchase, check the final price and verify that you're buying from a legitimate seller.
虽然便捷的购物体验很重要，但基本的购物安全习惯依然不可忽视。如果你需要更多关于如何识别可疑卖家的信息，可以参考我们的指南。

我挺喜欢“在一个地方集中记录所有想购买的商品”的这个想法，尤其是在节日期间。价格提醒功能确实会很有帮助；如果谷歌的人工智能能帮你找到我可能错过的折扣码，那我当然支持这样的功能。不过，我也在关注这项技术的未来发展方向。谷歌正在让购物变得越来越便捷，但这种便利性也可能带来负面影响——当公司掌握了你的购物偏好后，你重新考虑购买决策的时间就会变少。
I like the idea of having one place to keep track of everything I'm considering buying, especially when the holidays roll around. The price alerts could be genuinely helpful. And if Google's AI can find a discount code I would have otherwise missed, I'm all for it. But I'm also watching where this is heading. Google is making shopping increasingly convenient, and that convenience can be a double-edged sword. When a company knows what you're interested in buying and makes checkout easier, there's less time to reconsider a purchase.
我的建议是：利用 Universal Cart 来做好购物前的准备工作，从而节省开支；但千万不要让技术替你做出购买决定。
My advice? Use Universal Cart to do your homework and save money. Just don't let the technology do the deciding for you.
