Small, focused Shopify apps for the jobs that should not need a heavyweight platform: checking catalog data, clarifying shipping, adding gifting, matching storefront content, and recovering restock demand.
Each app has one clear job and a deliberately narrow data footprint. Three are published on the Shopify App Store today; three are in review.
Snow, confetti and falling leaves on your storefront — scheduled in advance, with zero layout shift.
Turn missing and inconsistent product data into a practical, ordered cleanup list.
Let shoppers estimate the Shopify rates for their cart before they reach checkout.
Give shoppers a clear way to add merchant-defined wrap options and gifting instructions.
Match cosmetic storefront content to the campaign and visitor context — without building shopper profiles.
Capture demand on sold-out variants and notify waiting shoppers when inventory returns.
The software stays narrow and understandable. If you want a human to configure it, review the findings, or help with the underlying store problem, that conversation is free too.
These tools are being built without an app subscription fee. There is no feature ladder to decode before the app can do its core job.
Catalog checks and storefront rules explain what matched and why. The tools do not turn a simple utility into an AI black box.
Book a setup conversation when you want help applying the tool, cleaning the catalog, or improving the surrounding workflow.
Kernvel Catalog & Feed Audit, Back in Stock, and Seasonal Effects are published on the Shopify App Store today. Shipping Calculator, Gift Wrap, and Personalization are in review — we will add each app's install link on this page as soon as Shopify approves it.
The product model has no app subscription fee. The optional setup conversation is free as well. If a merchant later asks Kernvel to perform broader done-for-you work, that separate service is quoted clearly before any work begins.
No. Catalog & Feed Audit is a read-only auditor. It reports findings and links you to the relevant products; it does not rewrite catalog data.
No. The Free Tools line uses explicit checks and rules for focused utility work. Kernvel's paid IQ apps are the separate product line for deeper AI-enabled operations.
The apps are still moving through launch validation, but the Kernvel team can already help map the right setup for your catalog, cart, theme, or inventory workflow.
