ChatGPT vs Gemini vs Perplexity: Which AI Gives the Best Shopping Advice?

Shopping online used to mean opening dozens of browser tabs and spending hours comparing products. Now, AI shopping assistants like ChatGPT, Gemini, and Perplexity promise to do all that work for you. But which one actually helps you make better buying decisions? This article breaks down how each AI tool handles shopping advice, from finding the right laptop to picking the perfect gift. We tested all three platforms to show you which one deserves a spot in your shopping routine.

What Are AI Shopping Assistants and Why Do They Matter?

AI shopping assistants are smart tools that use artificial intelligence to help you find products, compare prices, and make purchase decisions. Think of them as your personal shopping buddy who never gets tired of searching.

These tools work differently from regular search engines. Instead of just showing you links, they actually understand what you need and give you specific recommendations.

ChatGPT offers guidance similar to a shopping concierge, asking questions to narrow down your preferences Yahoo!, while Google Gemini uses its Shopping Graph with over 50 billion product listings Yahoo!.

The big three players in this space are:

ChatGPT by OpenAI – Known for conversational help and detailed product guides Google Gemini – Connected to Google’s massive shopping network Perplexity AI – Focused on accuracy with sources and citations

How ChatGPT Handles Shopping Advice

The Shopping Research Feature

ChatGPT introduced shopping research as a new experience that builds thoughtful guides to help users decide between products OpenAI. When you ask ChatGPT to help you shop, it does not just throw products at you randomly.

The process works like this:

1. You tell ChatGPT what you want (like “find me a quiet vacuum for under $200”)
2. It asks you follow-up questions about your needs
3. The tool provides multiple-choice questions to clarify interests, such as screen size preferences or whether you value battery life over performance Yahoo!
4. After a few minutes, you get a complete buyer’s guide with pros and cons

ChatGPT’s Strengths for Shopping

The conversational approach makes ChatGPT feel natural. It remembers what you said earlier in the chat and builds on that information. If you mentioned you have a small apartment, it will suggest compact products.

ChatGPT got testers closest to actually making a purchase, largely thanks to the familiar chat layout and generous product links Vudoo. The interface shows product cards you can like or dislike, which helps the AI understand your taste better.

Where ChatGPT Falls Short

One major problem is that Amazon prevents ChatGPT from scraping its site, blocking it from offering options from Amazon’s massive product catalog Fortune. This is a huge gap since Amazon sells almost everything.

All links provided often went to Best Buy with no Amazon or other deals, and pricing and availability are not always perfectly up-to-date Yahoo!. You might find a great recommendation but then discover the price changed or the item is out of stock.

The tool also needs a few minutes to think, which means it is not great for quick questions like “what’s the price of this specific phone?”

Google Gemini’s Approach to Shopping

Integration with Google Shopping

Google Gemini has a massive advantage because it connects to Google’s entire shopping system. The backbone is Google’s Shopping Graph, which contains more than 50 billion product listings that are continuously updated across retailers Yahoo!.

Unlike ChatGPT, Gemini does not always ask follow-up questions. It assumes reasonable defaults and provides a range of options with links to multiple retailers for each item Yahoo!.

Unique Features of Gemini

One cool feature is the “call-store” option. Depending on what you search for, Gemini might dial local retailers and ask about inventory, promotions, or when a product is in stock Yahoo!. This bridges online and offline shopping in a smart way.

Gemini also shows price history for some products, which helps you know if you are getting a good deal or if prices usually drop more during sales.

Gemini’s Limitations

The basic free version of Gemini is pretty bare. The most basic version had the least visually impactful interface, with all responses purely in text with a handful of outbound links Vudoo.

The basic version is not an accurate representation of its shopping power and would leave most shoppers wanting more Vudoo. You need access to Google’s enhanced AI Mode to get the full shopping experience, which is not yet available to everyone.

Perplexity’s Shopping Tools Explained

The New Shopping Tab

Perplexity recently launched dedicated shopping features. The shopping search is set up as a tab option where typing what you want produces a clean grid of product cards Yahoo!.

Each product card shows:

• Customer ratings
• Current price
• Positive aspects (like “easy to upgrade”)
• Negative aspects (like “battery life could be better”)

Instant Buy and Citations

The instant buy button offers integrated checkout options via partnerships with supported merchants Yahoo!. This means you can complete purchases without leaving Perplexity, at least for certain stores.

The biggest advantage Perplexity has over competitors is source citations. Perplexity’s recommendation reads like a college paper with a summary that is footnoted with sources MarTech. You can see exactly where the information came from, which builds trust.

Perplexity’s Drawbacks

The instant buy feature sounds great but has limited availability. When tested, instant buy was not available on enterprise accounts, and only a handful of brands and products offered the option Fortune.

The tool is still new to shopping, so its product database is smaller than ChatGPT or Gemini. Perplexity was probably more adept at giving information about retailers and products than landing users on a checkout page Vudoo.

Head-to-Head Comparison: Real Shopping Tests

Finding a Specific Product

When searching for specific items (like white Adidas Samba sneakers in size 9), all three tools performed reasonably well. Gemini was fairly generous with results and included links out to stores that carried them Vudoo.

ChatGPT asked clarifying questions before searching, which took longer but produced more targeted results. Perplexity gave quick results with clear product cards but fewer total options.

Shopping with a Budget

For budget-constrained searches (like “laptop under $800”), ChatGPT went through a series of multiple-choice questions about screen size, battery life, and portability importance Yahoo!. This approach helped narrow down choices effectively.

Gemini provided a wider range of options across different price points within the budget. Perplexity showed fewer options but included more detailed pros and cons for each product.

Gift Shopping

Gift recommendations revealed interesting differences. When asked to suggest gifts for a child who loves art, ChatGPT asked about the child’s age and skill level first. Gemini immediately suggested products based on common search patterns. Perplexity provided options with clear reasoning about why each gift might work.

Instead of asking “I need a laptop,” try “I need a lightweight laptop under $900 with at least 8 hours battery life for video editing.” The more details you provide, the better recommendations you will get.

Do not settle for the first answer. Ask the AI tool to explain why it recommended certain products or to show cheaper alternatives. ChatGPT allows users to guide research by interacting with products and marking items as not interested or more like this Yahoo!.
