# Prerequisites for enhanced chat

# Prerequisites for enhanced chat {#ariaid-title1}

Release version: Brazil

Before configuring enhanced chat for ServiceNow Otto for Virtual Agent, your environment must meet the requirements for your deployment channel.

Requirements differ depending on whether you're deploying enhanced chat in a Service Portal or a mobile app.

## Service Portal {#va-prereqs__va-prereqs-service-portal}

Enhanced chat in a portal includes a resizable chat window and an integrated search experience. To support search, your portal must have AI Search enabled. If you only need the chat experience without search, AI Search is not required, but your portal must include the default chat button widget. The full-page experience is an optional addition to enhanced chat. Both configurations require specific portal
widgets to be in place. If you have customized the Faceted Search widget or the Typeahead Search widget, reconcile those customizations with the latest widget versions before you begin configuration.

## Mobile app {#va-prereqs__section_q5b_mwk_jkc}

Enhanced chat in a mobile app supports three components: a mobile search widget, a chat launcher, and a custom app built with the Mobile SDK. Prerequisites and available capabilities vary by component. The mobile search widget supports the full-page experience only and requires a mobile search configuration. The chat launcher and custom app support native Virtual Agent with ServiceNow Otto for Virtual Agent responses.  
Note:  
The AI Search experience is not available in custom apps.

For component-specific prerequisites, see [Portal prerequisites for enhanced chat](https://www.servicenow.com/docs/JTghBpfLqIH4krWfRrZZ_g "ServiceNow Otto for Virtual Agent provides users with a content-driven and search-driven generative AI experience. To benefit from chat and search capabilities, your portal must have AI Search enabled before configuring your assistant.") and [Mobile app prerequisites for enhanced chat](https://www.servicenow.com/docs/pGG~wDmRkN32LKawXRUEOQ "ServiceNow Otto for Virtual Agent provides users with a content-driven and search-driven generative AI experience. Depending on whether you have opted into standard or enhanced chat when configuring your assistant, you can integrate three different mobile app components with an assistant.").
