 Once Claude Desktop starts, attachments will be available that correspond to the [datasets available to the Trieve organization](https://docs.trieve.ai/guides/create-organizations-and-dataset). These can be used to select a dataset. After that, begin chatting with Claude and ask for information about the dataset. Claude will use search as needed in order to filter and break down queries, and may make multiple queries depending on your task.
