-= Triage alerts with Elastic AI Assistant
+= Triage alerts
 Elastic AI Assistant can help you enhance and streamline your alert triage workflows by assessing multiple recent alerts in your environment, and helping you interpret an alert and its context. 
 
 When you view an alert in {elastic-sec}, details such as related documents, hosts, and users appear alongside a synopsis of the events that triggered the alert. This data provides a starting point for understanding a potential threat. AI Assistant can answer questions about this data and offer insights and actionable recommendations to remediate the issue.

+Elastic AI Assistant can help you learn about and leverage the Elasticsearch Query Language ({esql}). 
+
+With AI Assistant's <<ai-assistant-knowledge-base, {esql} knowledge base>> enabled, AI Assistant benefits from specialized training data that enables it to answer questions related to {esql} at an expert level. 
+
+AI Assistant can help with {esql} in many ways, including:
+
+* **Education and training**: AI Assistant can serve as a powerful {esql} learning tool. Ask it for examples, explanations of complex queries, and best practices.
+* **Writing new queries**: Prompt AI Assistant to provide a query that accomplishes a particular task, and it will generate a query matching your description. For example: "Write a query to identify documents with `curl.exe` usage and calculate the sum of `destination.bytes`" or "What query would return all user logins to [a host] in the last six hours?"
+* **Providing feedback to optimize existing queries**: Send AI Assistant a query you want to work on and ask it for improvements, refactoring, a general assessment, or to optimize the query's performance with large data sets.
+* **Customizing queries for your environment**: Since each environment is unique, you may need to customize queries that you used in other contexts. AI Assistant can suggest necessary modifications based on contextual information you provide. 
+* **Troubleshooting**: Having trouble with a query or getting unexpected results? Ask AI Assistant to help you troubleshoot.
+
+In these ways and others, AI Assistant can enable you to make use of {esql}'s advanced search capabilities to accomplish goals across {elastic-sec}.

+== Use Attack discovery to identify threats
+Attack discovery can detect a wide range of threats by finding relationships among alerts that may indicate a coordinated attack. This enables you to comprehend how threats move through and affect your systems. Attack discovery generates a detailed summary of each potential threat, which can serve as the basis for further analysis. Learn how to <<attack-discovery,get started with Attack discovery>>.
+
+image::images/attck-disc-11-alerts-disc.png[An Attack discovery card showing an attack with 11 related alerts,90%]
+
+In the example above, Attack discovery found connections between eleven alerts, and used them to identify and describe an attack chain.

+== Use AI Assistant to analyze a threat
+
+From a discovery on the Attack discovery page, click **View in AI Assistant** to start a chat that includes the discovery as context. 
+
+AI Assistant can quickly compile essential data and provide suggestions to help you generate an incident report and plan an effective response. You can ask it to provide relevant data or answer questions, such as “How can I remediate this threat?” or “What {esql} query would isolate actions taken by this user?”

+
+If you add a message that contains a discovery to a case, AI Assistant automatically adds the attack summary and all associated alerts to the case. You can also add AI Assistant messages that contain remediation steps and relevant data to the case.

+[[use-case-incident-reporting-translate]]
+== Translate incident information to a different human language using AI Assistant
+AI Assistant can translate its findings into other human languages, helping to enable collaboration among global security teams, and making it easier to operate within multilingual organizations. 
+
+After AI Assistant provides information in one language, you can ask it to translate its responses. For example, if it provides remediation steps for an incident, you can instruct it to “Translate these remediation steps into Japanese.” You can then add the translated output to a case. This can help team members receive the same information and insights regardless of their primary language.
+
+NOTE: In our internal testing, AI Assistant translations preserved the accuracy of the original content. However, all LLMs can make mistakes, so use caution.
