# Yikfy > Yikfy is a Shopify app that uses AI to bulk-optimize product catalogs: it generates product descriptions, SEO meta titles and descriptions, tags, collections and images, and translates catalogs across multiple languages. Merchants review all AI output before publishing; merchant and customer data is never used to train AI models. The marketing site is a landing page available in six languages (English, Italiano, Español, Deutsch, Français, Português), plus an English-only blog. Each language version of the landing page has the same content at its own URL, with `/en` as the default (`x-default`). ## Main pages - [Home (English)](https://www.yikfy.com/en): product overview, features, pricing and FAQ. - [Home (Italiano)](https://www.yikfy.com/it): product overview, features, pricing and FAQ. - [Home (Español)](https://www.yikfy.com/es): product overview, features, pricing and FAQ. - [Home (Deutsch)](https://www.yikfy.com/de): product overview, features, pricing and FAQ. - [Home (Français)](https://www.yikfy.com/fr): product overview, features, pricing and FAQ. - [Home (Português)](https://www.yikfy.com/pt): product overview, features, pricing and FAQ. - [About the author](https://www.yikfy.com/en/about): who writes here and why. ## Product - [Install Yikfy on the Shopify App Store](https://apps.shopify.com/yikfy-ai-bulk-product-seo?utm_source=yikfy_site&utm_medium=llms_txt&utm_campaign=site): install the app and start with a free trial (no credit card required). ## Free tools - [SERP preview and meta length checker](https://www.yikfy.com/en/tools/serp-preview): paste a meta title and description and see where Google truncates them, measured in pixels on desktop and mobile, including the store name Shopify themes append to the title.
