TikTok adds in-app checkout and a shopping assistant to its advertiser tools.
TikTok unveiled Buy Direct checkout, a Shopping Assistant agent and a US ad network across 400,000 apps at Advertising Week New York.
At Advertising Week New York on 5 October 2026, TikTok announced a batch of AI tools for advertisers and sellers, running from checkout inside the app to an ad network that reaches beyond it.
The full list is in TikTok’s announcement.
The two products that touch every brand selling on the app are Buy Direct and Shopping Assistant. Buy Direct is an in-app checkout that lets someone buy straight from a brand, from the For You feed, with one click and without leaving TikTok. Shopping Assistant is a conversational agent that answers questions about product details, shipping, sizing, availability and purchasing inside one conversation, and TikTok says it will sit in several places in the app. TikTok calls these its first Agentic Commerce experiences and names Salesforce, Shopify, Shoplazza and Stripe among the commerce and payment partners it is building them with.
The rest of the announcement
- Agentic Leads: an agent that holds a conversation to capture and qualify sales leads, planned for TikTok Direct Messages and for lead forms on a brand’s own website.
- TikTok Ad Network: now open to US advertisers, extending campaigns to nearly 400,000 apps outside TikTok, run from TikTok Ads Manager with brand safety and placement controls.
- Search Ads Campaign, powered by Smart+: automated keyword, creative and budget handling for ads shown against searches on TikTok.
- Smart+ Creative Selection: one approval screen for a brand’s own assets, creative generated by Symphony and creator content.
- GMV Max: TikTok Shop’s automated campaign tool will take affiliate commissions, coupons and referral fees into account, so sellers can judge a true return.
- TikTok for Business MCP: the connector that lets AI agents plan, launch and manage TikTok ad campaigns is now listed in Claude, Kimi, Manus, Perplexity, Replit, Snowflake, Tencent WorkBuddy and the IAB Tech Lab Agent Registry. TikTok says advertisers using it rose by more than 200% since launch, citing its own data for July to September 2026.
TikTok also quoted Kantar’s Media Reactions 2026 report, which ranked TikTok first among the platforms where marketers plan to increase ad spend in 2027, with 84% of marketers placing ads there.
What TikTok has not said
Apart from the ad network’s US availability, the announcement gives no launch dates and no markets. Until TikTok says otherwise, a UK team should treat Buy Direct, Shopping Assistant and Agentic Leads as announced rather than available.
What it means for brands
Buy Direct and Shopping Assistant move the sale into the feed. When they reach your market, a product video is a shop window with a till under it, and the assistant answers sizing, shipping and stock questions from the product information it is given, so thin or out of date catalogue detail costs sales in a place you cannot see. This week, check that every product your TikTok videos feature has complete, current details in your shop catalogue, and pull the product questions from your recent comments, because those are exactly the questions the assistant is built to answer.
