The solution is an optional complement to the core {{es}} [search capabilities](/solutions/search.md) which are available through APIs across all deployment types, solutions, and project types.[^api-note]
+
+These UI affordances are exclusive to the {{es}} solution (on non-serverless deployments) and the {{es}} serverless project type.
+

+## Features and tools
+
+The {{es}} solution provides the following specialized UI tools and features to help you build search applications faster:
+
+### 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
+
+[Playground](/solutions/elasticsearch-solution-project/playground.md) lets you use large language models (LLMs) to understand, explore, and analyze your {{es}} data using retrieval augmented generation (RAG), via a chat interface. Playground is also useful for testing and debugging your {{es}} queries using the [retrievers](/solutions/search/retrievers-overview.md) syntax.
+
+### Synonyms UI
+
+The [synonyms UI](/solutions/search/full-text/search-with-synonyms.md#method-1-kib-ui) enables managing synonym sets directly within {{kib}}. This makes it easier to improve search relevance without editing configuration files.
+
+### Query Rules UI
+
+The [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.
+
+### 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.
+
+For a deeper understanding of search concepts and techniques, refer to the [Search use case](/solutions/search.md) documentation.
