Brand Harmony Tool

A Shopify app that scored product copy against a brand vision, retired

Brand Harmony Tool was my first Shopify app. You wrote down what your lifestyle brand stands for, and a language model rated each product description from 1 to 100 on how well it carried that. It shipped in late 2023 and taught me the whole Shopify pipeline, from listing to review to billing.

It never found a market. I had built it from a cool model, not from a merchant’s problem.

The lesson is in Product-Market Fit Mismatches: App 2 Postmortem, and the build itself in the Stair Step Method series.
