Albus can turn complex topics into bite-sized pieces to help you with your learning. Select 'Information breakdown' from the toolbar, and enter the topic you want to breakdown. Once you clicked each of the seven subtopics, it will turn into a content block on your board, and disappears from the list.
You can use information breakdown on the 'Ask anything' box as well. While getting answers to your questions, just click on the 'Breakdown' icon hovering the box to get a list of seven subtopics generated from your question.
