+
+The {{es}} solution and serverless project type provide specialized UI tools and interfaces that help you build search applications on top of the {{es}} platform.
+
+These UI affordances are exclusive to the {{es}} **solution** (on non-serverless deployments) and the {{es}} serverless **project type**. They complement the core [search primitives](/solutions/search.md) available across all Elastic deployments.
+
+## Features and tools
+
+The {{es}} solution provides the following specialized UI tools:
+
+### Agent Builder
+
+[Agent Builder](/solutions/elasticsearch-solution-project/elastic-agent-builder.md) enables you to create AI agents that can interact with your {{es}} data, execute queries, and provide intelligent responses. It provides a complete framework for building conversational AI experiences on top of your search infrastructure.

Playground is also useful for testing and debugging your {{es}} queries using the [retrievers](/solutions/search/retrievers-overview.md) syntax.
+
+### Synonyms UI
+
+The [Search with synonyms](/solutions/search/full-text/search-with-synonyms.md) interface provides a dedicated UI for managing synonym sets directly within {{kib}}, making it easier to improve search relevance without editing configuration files.
+
+### Query Rules UI
+
+[Query Rules UI](/solutions/elasticsearch-solution-project/query-rules-ui.md) enables you to create and manage query rules that modify search behavior based on specific conditions, helping you deliver more relevant results for common queries.
+
+### AI Assistant
+
+The [AI Assistant](/solutions/elasticsearch-solution-project/ai-assistant.md) provides intelligent assistance and insights across the Elastic platform, helping you understand your data and workflows more effectively.
+
+### Model Context Protocol (MCP)
+
+The [Model Context Protocol (MCP)](/solutions/elasticsearch-solution-project/mcp.md) lets you connect AI agents and assistants to your {{es}} data to enable natural language interactions with your indices.
+
+## Get started
+
+Ready to start using the {{es}} solution? Refer to [Get started](/solutions/elasticsearch-solution-project/get-started.md) for setup instructions and quickstart guides.
