# Analysis templates in AWS Clean Rooms
<a name="create-analysis-template"></a>

Analysis templates work with the [Custom analysis rule in AWS Clean Rooms](analysis-rules-custom.md). With an analysis template, you can define parameters to help you reuse the same query. AWS Clean Rooms supports a subset of parameterization with literal values. 

Analysis templates are collaboration-specific. For each collaboration, members can only see the queries in that collaboration. If you plan to use differential privacy in a collaboration, you should make sure that your analysis templates are compatible with the [general-purpose query structure](analysis-rules-custom.md#dp-query-structure-syntax) of AWS Clean Rooms Differential Privacy.

You can create an analysis template in two ways: using SQL code or using Python code for Spark.
