ChatGPT Shopping combines image-based product search, an AI research mode called Shopping Research, and side-by-side comparison tables, built on a version of GPT-5 tuned for shopping tasks. OpenAI ended in-chat purchasing on March 24, 2026, leaving Google's agentic checkout and Perplexity's Buy with Pro as the two AI assistants that can still finish a sale in-app.
Summary: ChatGPT's Shopping Research still produces the most detailed AI buyer's guides of the three major assistants, but OpenAI discontinued Instant Checkout on March 24, 2026, five months after its launch. Perplexity's Buy with Pro and Google's agentic checkout still complete purchases inside their own apps. None of the three tools can read Amazon's product catalog.
Tap "Buy" on a product card in ChatGPT today and for most items nothing happens the way it did in September 2025. OpenAI launched Instant Checkout on September 29, 2025, built with Stripe on an open standard called the Agentic Commerce Protocol, and pitched it as the end of leaving the chat to pay. On March 24, 2026, five months later, OpenAI pulled it back. The company said the first version "did not offer the level of flexibility that we aspire to provide," and handed checkout back to merchants.
That reversal matters if you are choosing which AI assistant to use for a real purchase this week. This guide covers the three that actually do shopping research well right now: ChatGPT, Perplexity, and Gemini. You will get a criteria list to judge any of them, a shortlist with the real caveat for each, and a direct answer to the question every one of them dodges: which one can still finish the sale without sending you to a browser tab.
Five questions separate a genuinely useful shopping assistant from a search box with a nicer font. Test any tool against these before you trust it with a $200 decision.
Does it search by image, not just keywords? You should be able to upload a photo and get back the product or its closest match, not a request to describe what you're looking at in words.
Does it produce a structured comparison, not just a list? A real buyer's guide maps price, specs, and your stated constraints across a shortlist. A wall of product cards is not the same thing.
Can you steer it in a live conversation? "Remove anything over $150" or "show me only the wide-fit options" should re-run the search, not start it over.
Can it actually finish the purchase, or does it hand you off? This is the question that changed answer between March and now, and it is the one most existing shopping-AI explainers get wrong because they were written before the change.
Does it see Amazon? None of the three below can, as of this guide. Amazon added dozens of AI crawler identifiers, including OpenAI's ChatGPT-User and OAI-SearchBot, to its robots.txt file, so all three tools work around Amazon's catalog rather than through it.
ChatGPT's Shopping Research mode is the deepest of the three, built on a version of GPT-5 tuned specifically for shopping tasks. Ask a specific question with real constraints attached, and it asks two or three follow-ups, searches in the background for two to four minutes, and returns a document: a plain-language explainer, ranked picks with reasons, and a side-by-side comparison table you can keep editing in conversation.
It runs on Free, Go, Plus, and Pro plans, on iOS, Android, and web. The caveat: since March 24, 2026, nothing you find this way can be paid for inside the chat for most merchants. You click through to the retailer.
Perplexity built the opposite trade-off. Its shopping tools, Snap to Shop for visual search and Buy with Pro for checkout, are built on Shopify's Shop Pay, so a Pro subscriber ($20 a month, $200 a year) can complete a purchase from a participating Shopify merchant without leaving Perplexity. The research step is thinner than ChatGPT's, closer to an annotated product list than a structured guide. The caveat: the checkout that actually works is behind a paywall, and coverage is limited to merchants running Shop Pay.
Gemini sits in the middle. Google's own agentic checkout, live since November 13, 2025 with Wayfair, Chewy, Quince, and a growing list of Shopify merchants, lets a shopper set a price target and let the agent buy automatically once it's hit, confirmed by the user at the final step. Gemini's research output is closer to search results with images than a written buyer's guide. If you already have Search open more than ChatGPT or Perplexity, it is the path of least friction, not the deepest research.
Microsoft Copilot is worth a mention only to rule it out. It can browse and summarize product pages on request, but it has no dedicated shopping research mode and no in-platform checkout as of this guide. Claude is the same story: strong for general research, no shopping-specific mode at all. Skip both for this specific job.
Visual search is the one feature all three tools share, and it is worth knowing the mechanics because it is faster than typing a description when you have a photo.
Step 1: Open the attachment tool. Tap the paperclip icon in the ChatGPT chat bar, on mobile or web.
Step 2: Add the picture. Pull one from your phone's gallery, grab a screenshot, or drop in a link to an image hosted somewhere else.
Step 3: Ask a direct question. "Identify this and tell me who sells it cheapest" or "find something similar under $80" both work. Vague prompts like "cool right?" return nothing useful.
Step 4: Work the result. ChatGPT hands back product cards with prices, star ratings, and condensed reviews. Tap "Ask about this" on any card to compare it against similar items without starting a new search.
Visual search works best on fashion, furniture, tech accessories, and home decor, where the shape and finish of an object carry most of the identifying information. It works worse on commodities like cables, batteries, or generic hardware, where one black rectangle looks like the next.
Here is what actually happens when you run a complex query through Shopping Research, using noise-cancelling headphones as the example.
Step 1. Describe the constraint set in one message: a $200 to $300 budget, needs to pair with both a MacBook and an Android phone, and gets used on flights twice a month.
Step 2. ChatGPT asks two or three follow-up questions: over-ear or in-ear, brand preferences, how much you care about call quality. Answer them specifically. Vague answers produce a vague shortlist.
Step 3. Research runs in the background for two to four minutes. Product cards populate as they are found. Mark anything outside the budget "Not interested" and anything close "More like this," and the shortlist adjusts without restarting.
Step 4. You get the buyer's guide: a written explanation, ranked picks with individual reasoning, and the comparison table mapping battery life, noise cancellation rating, and multipoint pairing across the shortlist. Ask a follow-up inside it, such as which option has the strongest reviews for call clarity on a plane, and it re-runs a targeted search rather than starting over.
Step 5. Click through to the retailer to actually buy, since Instant Checkout is no longer available for most merchants. Confirm the price and size on the retailer's own page before paying. Total time runs six to ten minutes, and the tab count stays at one until the final checkout page.
Most people picking between AI shopping tools are choosing between these two, so it is worth naming a winner for a specific case rather than leaving it vague.
Pick 0 if the decision is complex and the purchase is over roughly $150. A laptop, a stroller, noise-cancelling headphones with brand and compatibility constraints, anything with six variables you'd otherwise research across five open tabs. The structured comparison table and the ability to keep refining it in conversation is worth the extra click to the retailer's own checkout.
Pick 0 if you already know what you want and just want to pay fast. A restock of something you've bought before, a gift from a Shopify-run store, anything where research isn't really the job. Buy with Pro removes the checkout step entirely for supported merchants, which ChatGPT currently cannot.
Neither is the right tool if the product you want is sold primarily on Amazon. Type the query into either one and you will get alternatives, not the Amazon listing itself, because of the robots.txt block described above. For an Amazon-specific purchase, search Amazon directly.
Three cases where none of this is worth the setup. A purchase under $30, where the research time costs more than a wrong guess. A category where you already have a trusted specific brand and size, where a search box gets you there in one query. And any purchase that needs to happen inside a store today, because none of these three reliably reflects local stock; they read online retail data, not a specific store's shelf.
If none of those apply, and the decision has real variables, the criteria list above still holds regardless of which assistant you already have open.
The obvious objection: if OpenAI itself killed in-chat checkout after five months, maybe the entire "AI does your shopping" pitch is overbuilt, and a search engine with good filters would have done the job. That is a fair read of what happened. OpenAI's own explanation named the actual failure: fewer than 15 of Shopify's millions of merchants ever went live with Instant Checkout in its first five months, a near-total no-show from the supply side, not a demand problem.
But the research half of the pitch held up where the checkout half didn't. Adobe measured a 693.4% year-over-year surge in AI-referred retail traffic over the 2025 holiday season, and Salesforce found that traffic converting at roughly nine times the rate of social referrals. Shoppers are using these tools to decide, even while merchants were not ready to let them pay.
The honest verdict is narrower than the pitch either company made in 2025. Use the AI for research, expect to pay somewhere else, and treat any guide, including an older version of this one, that describes ChatGPT completing your purchase as five months out of date.
If you run a Shopify store, a DTC brand, or any online catalog, the checkout story above changes what to prioritize.
Submit your product feed through OpenAI's merchant allowlisting process so ChatGPT can read accurate specs and pricing, even though it will not process the sale. Do the same for Google's Shopify Catalog integration if you want to appear in Gemini's agentic checkout flow, which is live and adding merchants. If Shop Pay is part of your existing Shopify setup, you already qualify for Perplexity's Buy with Pro without extra integration work.
Clean structured data and accurate, current pricing now matter more than keyword-stuffed product copy, because these tools are reading your page as source material for a recommendation, not indexing it for a search rank.
Watch whether Google's agentic checkout crosses meaningfully past its current handful of named partners by the end of 2026. If Wayfair, Chewy, and Quince turn into fifty recognizable retailers, Gemini becomes the default answer to "which AI can actually buy this for me," and this guide's verdict flips. If it stalls at a handful of names the way Instant Checkout did, expect Google to quietly narrow its ambitions the same way OpenAI did in March.
Not for most merchants. OpenAI discontinued the original Instant Checkout feature on March 24, 2026, about five months after it launched, and said the initial version did not offer the flexibility it wanted. ChatGPT still finds and compares products, but for most items it now sends you to the retailer's own site to pay.
Instant Checkout launched on September 29, 2025, built with Stripe on the Agentic Commerce Protocol, and let U.S. users buy from Etsy and select Shopify merchants inside the chat. OpenAI pulled it back in March 2026 after most eligible merchants never activated it, and shifted its focus to product discovery instead.
Tap the attachment icon in the chat bar and upload a photo, a screenshot, or an image URL, then ask what the item is or where to buy something similar. ChatGPT returns product cards with prices, ratings, and retailer links. This works on Free, Go, Plus, and Pro plans.
Yes. Shopping Research, the visual search tool, and the comparison tables are available to logged-in users on the free plan, not just paid tiers. The feature that now sits behind a subscription is checkout, and only on Perplexity's Buy with Pro, which requires its $20-a-month Pro plan.
Perplexity and Gemini can, ChatGPT currently cannot for most merchants. Perplexity's Buy with Pro completes purchases through Shopify's Shop Pay for Pro subscribers, and Google's agentic checkout has worked with Wayfair, Chewy, and Quince since November 2025. ChatGPT's own in-chat checkout was discontinued in March 2026.
