Hello, and happy Sunday! This week on Every, we explored the Venn diagram of artificial intelligence and note-taking: Jillian Hess detailed the (pre-AI) note-taking prowess of biographer extraordinaire Robert Caro, and Notion cofounder Simon Last went on AI & I to discuss the note-taking company’s AI effort with Dan Shipper. Read on for more on that and everything else we published.—Kate Lee

Data mining

AI podcasts for the people. NotebookLM, Google’s note-taking and research assistant, is a rocket ship:

As a tool to query and interact with your own records and notes, NotebookLM has been around since July 2023. But visits to the NotebookLM site went parabolic in August, when Google launched a feature letting users make a podcast out of their notes. Keeping better track of all the information detritus we collect makes a lot of sense, especially for students and other research-oriented users. That’s not what drove its popularity, however. What mattered is the uncanny ability to generate NPR-intoned AI-hosted podcasts that discuss that information detritus. To what end? Who really knows. But the people love it.—Moses Sternstein

Alignment

Stop scrolling. Sometimes, in the endless stream of people telling you how to live a better life, you find something that makes you pause. This week it was Irish poet David Whyte on Tetragrammaton with Rick Rubin, hosted by the record producer-turned-creativity guru. Whyte makes stodgy executives in Patagonia vests confront their own mortality, then writes about it with the kind of clarity that makes you forget to check your phone—or that you even have a phone. This conversation isn’t meditation-lite or lunch-break mindfulness. Whyte speaks about presence like someone who has actually touched the electric fence of existence, the kind of presence that comes when you face the full weight of being alive—the light and the dark, the growth and the grief. Here's the one thing I'm taking away: The more you truly lose yourself in seeing something, the more clearly you find yourself.—Ashwin Sharma

Sentiment analysis

“The technical breakthrough itself does not quickly become popular, but rather the psychological factors triggered by the product that results from the application of technical innovation.”—A psychology student in response to Rhea Purohit’s piece about what makes technologies popular
