The retail operating system

One engine for every retail decision.

Most retailers run four or five separate tools.

Search in one tool, pricing in another, ads bolted on top — nobody owns the order shoppers see, and margin leaks between them. The Unified Decision Engine governs relevance, inventory, margin and sponsored demand in one pass, on every surface, including the AI assistants now doing the shopping.

Start with one surface. Leave the rest of your stack untouched.

How is AI chat ad inventory priced? | Particular Audience

AI chat ad inventory is usually priced on CPM, CPC, cost per sale or a flat sponsorship. Because an answer shows only a few products, each slot is scarcer.

How is AI chat ad inventory priced?

AI chat ad inventory is usually priced on CPM, CPC, cost per sale or a flat sponsorship. Because an answer shows only a few products, each slot is scarcer than a results-page slot, which should be reflected in rate cards.

CPM

Pay per thousand impressions. Define an impression as a sponsored product shown and labelled in a delivered answer.

CPC and cost per sale

Pay when the shopper opens or asks about the product, or buys it within an agreed window.

Sponsorship

Fixed ownership of a category or topic for a period, still subject to the relevance floor.

Run it with Particular Audience

Sponsored Prompts runs on Adaptive Transformer Search and the open-source ATS MCP server. Advertisers pick products or a collection; each item surfaces automatically, labelled, in chats, prompts and AI searches where it scores highly.

Frequently asked questions

Should chat cost more than site ads?

It depends on measured performance. Report chat inventory separately so advertisers can compare.

Can the bid override relevance?

No. Only relevant products enter the auction.
