Within the Uncountable interface, there are two main places where you can save visualizations, files, recipes, and any other data relevant to your project: the Project Notebook and project reports.
For each project, there is only a single Project Notebook which is automatically created when you create a new project. However, the Project Notebook will remain empty until you actively populate it with data. For some customers, the Project Notebook will appear as a location to save visualizations from the Explore Data page, experiment comparisons or upload any related files. Auto-generated with every Project Notebook are fields for Project Planning, including background on the project, involved stakeholders, and timelines.
In contrast, you can create multiple project reports within a single project. A project report can contain the same kinds of data/files/extra as the Project Notebook, but is curated by the user to reflect their specific needs.
