In order to save the current data and insights from Analytics panel, you can use the Project Notes.
Simply open the Notes dialogue (at the bottom) and then click "Add Analytics" button:
You can save as many iterations of Analytics data as you wish, which is especially useful as you're exploring the graph, so you can get a few insights and different views.
We always recommend to save the first analytics insights you get as you load the graph and to then add more content into notes as you go.
Later, you can export those insights as a text file or use it to generate AI content.
