Most reading disappears. Highlights pile up. The thought you had on page 40 is gone by page 200. Phenyx is an AI reading companion for people who want the book to stay with them.
You read, you write down what you’re actually thinking, and the app talks back — Socratic questions, not a summary. Over time it maps how your ideas connect across books, and it brings the important ones back when you’d otherwise forget them. Live on iOS.
