Turn long notes into instant insights with layers

Research into memory reveals that writing things down engages multiple brain areas—what psychologists call the “generation effect.” In the 1950s, Watson and Crick even built molecule models on a tabletop to turn intangible ideas into visible forms. Similarly, Progressive Summarization breaks your notes into layers so your future self never has to dig through paragraphs to find the core insight.

On a rainy Sunday afternoon, Jamal highlighted passages from an economics paper, then bolded the standout arguments, and finally highlighted one sentence that captured the concept of cost disease. That single line now sits at the top of his notes whenever he’s pitching a business case—saving him time and making his presentations more persuasive.

Layering your notes mirrors the scientific peer-review process: you filter, refine, and crystallize ideas until only the most rigorously tested insights remain. This makes every note a precision tool for decision-making rather than a dusty archive that never gets reopened.

When you’re reviewing saved excerpts tonight, focus on the sentences that spark curiosity—bold them first, then pick your most surprising quote to highlight. Before you close the app, draft two bullet points in your own words. You’ll wake up tomorrow with clarity on what truly matters from your reading.
