+#### LLMs
+This app can use a selection of open-weights language models hosted on the National Research Platform (https://nrp.ai/documentation/userdocs/ai/llm-managed/), and Open Router (https://openrouter.ai/models).

+
+### Why save your queries?
+Conservation researchers and practitioners are interested in **learning what matters most to our community**. 
+
+By saving your anonymous queries, we can identify which topics and areas are drawing the most attention, helping us improve future tools and data products to **better support conservation efforts**. We also save the LLM’s response to each query to monitor its accuracy and ensure the system is working as intended. 
+
+You can opt out at any time by disabling “Save query”.
