A search engine with pictures
People open Pinterest with a plan in mind: a kitchen, a wedding, a party, a new wardrobe. They find pins through search and related pins long after posting, so a pin behaves more like a product page than a social post. Titles of up to 100 characters, of which about the first 40 show in feeds, and descriptions of up to 800 should use the words people actually search. The imagery has to match the query literally: someone searching for small balcony gardens wants small balconies. Generation makes it practical to produce a specific pin for each cluster of searches instead of one generic image stretched across all of them.
The 2:3 frame and the overlay
Pinterest recommends 2:3 at 1000x1500; pins taller than that can be cut off in the feed. On a phone, pins sit in a narrow two-column grid, so any overlay must read at thumbnail size: a short phrase that names the idea, in type large enough to survive. Generate the image without words and set the overlay as a separate layer in the brand's typeface. Image models still mangle lettering, and a misspelt overlay on an otherwise polished pin looks careless in a way people remember. Keeping type separate also means one image can carry overlays in every language the brand sells in.
Seasons start months early
Pinterest users save ideas for Christmas, back-to-school, summer holidays and weddings well before the date, and seasonal pins need to be live when the planning starts, not when the shopping does. The obstacle has usually been photography: autumn scenes shot in autumn arrive too late for autumn planners. The studio removes that wait by generating seasonal scenes around real products, with product-lock keeping labels, shapes and colours exact, and by batch-producing pins straight from the product feed. A whole range can be staged for winter while the photography calendar is still on summer, and every pin still shows the product as sold.
Product pins and honest imagery
Product pins come from a catalogue data source and carry price and availability, so they need to stay in step with the feed. A generated lifestyle scene is fine; a pin that shows a different colour, size or finish from the product on the landing page is not. It drives returns, and it can amount to a misleading action under consumer protection law. Pinterest also labels images it identifies as AI-generated or AI-modified, and has given users ways to see fewer AI pins in some categories. Useful, accurate imagery of the real product is not the problem; generic synthetic scenes are what people tune out.
