+The AI agent in Mission Portal allows you to explore your infrastructure using natural language queries.
+
+- Integrates with common AI providers, including Google Gemini, OpenAI, Anthropic, and Mistral.
+- Supports running local models, through Ollama or using an OpenAI compatible API.
+- The model does not generate data directly, it generates SQL queries which are seamlessly executed against your database.
+- The resulting tables / SQL queries can be saved as reports.
+- The AI gets the context of your previous messages in the same chat, so you can refer back to things mentioned in the conversation.
+
+**Security and privacy**
+
+- Data (values) is never shared with the AI model provider, only schema and column names are sent along with your queries.
+- The UI allows you to inspect and verify the generated SQL queries.
+- SQL queries are run in read-only transactions.
+- The use of AI and choice of model and provider is up to you.
+  The feature must be enabled in the settings, and CFEngine Mission Portal communicates directly with the AI provider.
+
+## Chat
