## Platform — five layers, two interfaces
- [Conversational UI](https://chatcast.io/products/conversational-ui): a brand-trained assistant for human shoppers — chat, FAQ, recommendations, support. One surface, four skills, your live catalog as ground truth.
- [Agent Protocols](https://chatcast.io/products/agent-protocols): a public agent-protocol server (MCP, A2A, UCP, llms.txt, schema.org) so ChatGPT, Perplexity, Claude and Gemini can query your live catalog through one open standard.
- [Agentic Affiliates](https://chatcast.io/products/agentic-affiliates): campaigns, commission rates, attribution and settlement for the agentic web. Pay AI agents on performance when they bring shoppers to checkout.
- [Shopper Intent](https://chatcast.io/products/shopper-intent): a 66M-param commerce intent classifier — 13 intent types, 37ms latency, 11 accuracy points above GPT-4o, $0 per query.
- [Product Data Enrichment](https://chatcast.io/products/product-data-enrichment): the data layer underneath your store — attributes, policies, embeddings, schema — built and maintained automatically so every layer above reads the same ground truth.
