TikTok wants you to stop leaving the app when you buy something you saw in a video. On October 5, timed to Advertising Week in New York, the company announced two shopping features: Buy Direct, a one-click checkout that lets you buy from a brand straight from the For You feed, and Shopping Assistant, a chatbot that answers product questions before you pay. Both are starting in the U.S., and both are only available to brands through what TikTok calls "eligibility-based testing" for now, so most people won't see them right away.
We read TikTok's own business blog post on the launch alongside partner announcements and coverage, because the details matter more than the headline. The most interesting one is buried in a single sentence: Buy Direct requires brands to integrate the Universal Commerce Protocol (UCP), the open checkout standard Google introduced in January with Shopify, Etsy, Wayfair, Target and Walmart. TikTok is building its in-feed checkout on plumbing that Google designed for its own AI shopping tools.
How the two features actually work
Buy Direct is tied to TikTok's ads. When a participating brand runs a Buy Direct ad, you can tap once to buy using a payment method and address already saved in TikTok, and then track the order inside the app. The brand stays the merchant of record, which means it, not TikTok, handles the sale, the customer data, returns and support. That is the key difference from TikTok Shop, the marketplace TikTok launched in the U.S. in September 2023, where purchases run through TikTok's own storefront.
Shopping Assistant is less magical than "AI agent" might suggest. According to TikTok's post, it shows up as a chat window on a product page inside TikTok's in-app browser and answers questions about sizing, shipping, availability and similar details using information the merchant provides. From there you can keep going to the merchant's checkout, still inside TikTok. TikTok says the features are being built with Salesforce, Shopify, Shoplazza and Stripe, among others, and calls them the first of several "agentic commerce" tools.
Timing on the merchant side is worth noting. Salesforce's announcement says its UCP-powered checkout for TikTok will start a phased rollout in the first quarter of 2027. So for brands on Salesforce Commerce Cloud, at least, this is more of a 2027 story than an October one.
Everyone wants the checkout button, with mixed results
TikTok is moving in the opposite direction from OpenAI, and that's the context most launch coverage skipped. Here's how the main in-app checkout efforts stack up, based on each company's announcements and reporting by Modern Retail:
| Checkout | Started | Where you pay | Status now |
|---|---|---|---|
| TikTok Shop | Sep 2023 (U.S.) | TikTok's own marketplace | Running; about $15.8B in U.S. sales in 2025 (eMarketer estimate) |
| ChatGPT Instant Checkout | Sep 2025 | Inside ChatGPT, merchant handles fulfillment | Scaled back in March 2026; merchants now mostly use their own checkout |
| Google AI Mode and Gemini (UCP) | Jan 2026 | Inside Google, with Google Pay; merchant of record | Live for eligible Merchant Center sellers |
| TikTok Buy Direct (UCP) | Oct 2026 | In the For You feed, one tap; brand is merchant of record | Testing with eligible U.S. brands |
The ChatGPT row is the cautionary tale. OpenAI said in March that the first version of Instant Checkout "did not offer the level of flexibility" merchants wanted. Walmart's Daniel Danker told Wired that items sold directly inside the chatbot converted at a third of the rate of items that sent shoppers out to Walmart's own site, partly because people didn't want separate checkouts for each item. Retailers ended up treating ChatGPT as a place to be discovered rather than a place to sell.
TikTok's bet is that its situation is different, and there's a decent argument for that. People don't open TikTok to research a purchase the way they ask a chatbot for advice. They see something in a video and want it right then, which is the moment a one-tap button is built for. TikTok also has real evidence that its users buy: TechCrunch cites the eMarketer estimate that TikTok Shop's $15.8 billion was about 18% of U.S. social commerce in 2025. If you run that math backward ($15.8 billion divided by 0.18), the whole U.S. social commerce market comes out to roughly $88 billion, and every dollar of it that checks out inside TikTok without going through TikTok Shop is a dollar TikTok can now earn ad revenue on.
What it means for you
Our take: if you shop on TikTok, the one-tap button is convenient, but slow down on the first purchase and check who you're actually buying from. With Buy Direct, the brand is the seller, so returns and problems go to the brand rather than TikTok Shop's customer service. Treat Shopping Assistant's answers as the merchant's sales copy in chat form, since that's where its information comes from.
If you run a brand, this is worth a test, but not a rebuild. Buy Direct needs a UCP integration, which is the same work that gets you into Google's AI shopping surfaces, so the effort pays off twice. Watch your conversion and return rates closely, because the ChatGPT experience shows that putting a buy button in a new place doesn't guarantee people will press it.
