Audible

It analyzes 200+ hand-picked audiobooks across 5 genres (sci-fi, fantasy, thriller, business, self-development) and calculates a "Credit Value Score" for each one:

Cash price vs. your monthly credit ($14.95) Combined with rating and runtime Ranked into tiers: Legendary, Excellent, Great, Good You can search, filter by genre or value tier, sort by price/rating/runtime, and click through to each book's detail page. Everything is updated daily via the Amazon Creators API.

What I found:

A $45+ box set like Starship New Jersey gives you 3x the value of a $10 short listen Some highly-rated books are terrible credit value (buy those with cash) The best values tend to be sci-fi/fantasy box sets and classic long-form business titles Static site generated from Python + Jinja2, deployed on Cloudflare Pages. No login, no account, no ads – just a table that tells you where your next credit is best spent.

Would love feedback on the value scoring formula, missing genres, or features you'd want.
