Audible Credit Optimizer Reveals $40+ Value Gap in Subscriptions

A developer built a free tool that calculates the value of using an Audible credit versus buying a book outright, based on duration, rating, and price. The optimizer shows that a 53-hour classic like The Count of Monte Cristo scores 14.3, while a 1-hour book like The Art of War scores 0.2. The static Next.js site pre-renders 425 pages and refreshes data daily via GitHub Actions.
