Progressive Summarization is a technique that relies on summarizing a note in multiple stages over time. You save only the best excerpts from whatever you’re reading, and then create a summary of those excerpts, and then a summary of that summary, distilling the essence of the content at each stage. These “layers” are like a digital map that can be zoomed in or out to any level of detail you need. Progressive Summarization allows you to read the note in different ways for different purposes: in depth if you want to glean every detail, or at a high level if you just need the main takeaway. This allows you to review a note’s contents in seconds to decide if it’s useful for the task at hand.
