Pinterest Pin Description Character Limit: Make AI Respect It

Pinterest allows 100 characters in a pin title and 500 in a description, but mobile truncates a long one with an ellipsis, and a wall of overlay text buries the picture the pin is supposed to sell. This is PinFlow, my Shopify app. It writes the pin title, the description, the image overlay text and the alt text with a large language model, and you control all of it from one prompt box. What this demo covers: Why a long title and heavy overlay text make a bad pin The two AI tells people spot instantly: em dashes and emoji spam. PinFlow strips em dashes automatically Five built in prompt presets: Engaging, Informative, Question, Listicle and E-commerce The E-commerce preset, tuned to keep titles under 50 characters so nothing truncates on mobile Turning hashtags off completely, or down to one, by editing a single line of the prompt Asking for social proof and a call to action inside the description Changing the image overlay text from three words to four, and testing it live Editing the generated title, description and alt text by hand before you schedule the pin Generating every field in 40 languages, shown here in French, for stores using Shopify Markets PinFlow on the Shopify App Store: https://apps.shopify.com/pinflow
