IBM watsonx Assistant is an enterprise conversational AI platform for building virtual agents that answer customer questions across chat, voice, and messaging channels. IBM unveiled the product as Watson Assistant at its Think conference in March 2018, evolving out of the earlier Watson Conversation service, and folded it into the watsonx product family with a rebrand in 2024.
The platform combines a large language model with retrieval over a company's own documents and structured dialog flows, so an assistant can answer an open-ended question from a knowledge base and still follow a scripted path for something like a password reset or appointment booking. It plugs into channels including Salesforce, Zendesk, WhatsApp, Slack, Facebook Messenger, and Microsoft 365, and IBM positions it for organizations handling tens of thousands of customer interactions a month, citing banks, airlines, and healthcare systems among its deployments.
Smaller teams testing conversational AI can start on IBM's free plan before committing budget, while businesses running production support volumes move to the Plus plan at $140 a month for up to 1,000 users, or negotiate custom Enterprise pricing for larger deployments with dedicated support and advanced security controls.
