Blurbsprint

Blurbsprint is a web app (with optional mobile companion) that helps self-published authors write and validate high-converting book descriptions (blurbs) for Amazon, Kobo, and Shopify. It combines AI-assisted blurb drafting with structured genre frameworks, keyword hints, and a lightweight “market reality check” based on comparable titles you paste in. The app produces multiple blurb variants (hook-forward, trope-forward, review-style, short/long), then lets you run simple A/B tests by generating trackable landing pages or swap-ready blurbs for your store/newsletter. It also flags common conversion killers (too much plot, missing stakes, unclear genre signals, weak first line) and suggests concrete rewrites. This is not a magic sales machine: it’s a focused tool for one of the highest-leverage, most neglected assets in indie publishing—your product page copy.
