IBM offers watsonx Assistant, a platform that lets businesses build and deploy AI-powered chatbots and virtual agents to handle customer questions and support tasks across web, mobile, and voice channels.

Watsonx Assistant uses natural language understanding and IBM's large language models, including Granite, to interpret customer queries and deliver context-aware responses. Businesses can deploy branded assistants in existing websites, apps, or phone systems without writing code. A conversational search capability, using retrieval-augmented generation (RAG), allows the assistant to answer policy-grounded questions with little configuration. IBM also introduced purpose-built large speech models (LSMs) for telephone channels to improve voice recognition accuracy.
