Fundraising, hiring, the product, the customer who emailed twice, the accountant, the thing that will become a problem in three weeks. You capture all of it, because capture is the one part that works: Siri in the car, the Lock Screen at dinner, a Shortcut from your inbox.
What you get back is a wall of lines sorted by date. It cannot show you that the investor thread has not moved in nine days, or that the hiring line is blocked on a document only you can write, or that the product work is fine and could wait. Every morning you rebuild that picture from memory, and every morning it costs you the first hour.
