What problem does it solve? Shoppers often browse without buying immediately, and without a wishlist feature their saved items are lost across sessions, devices, and login events, leading to abandoned purchase intent and missed re-engagement opportunities. ## Core Features & Use Cases - Platform-Specific Setup: Step-by-step configuration for Shopify (Wishlist Plus, Growave), WooCommerce (YITH Wishlist), BigCommerce (native wishlists), and custom headless builds. - Guest Wishlist with Login Merge: localStorage-based guest wishlists that merge into server-side accounts on authentication, with deduplication by variantId and 90-day expiry. - Sharing and Back-in-Stock Alerts: Shareable wishlist links with privacy-safe rendering, plus back-in-stock email notifications using notifiedAt tracking to prevent duplicate sends. - Use Case: A fashion retailer adds heart toggle buttons to product cards, lets guests save items without an account, merges those items after signup, and emails customers when a saved out-of-stock dress is restocked. ## Quick Start Ask the AI to implement a wishlist feature for your store, specifying your platform (Shopify, WooCommerce, BigCommerce, or headless) and whether you need guest wishlists, sharing, or back-in-stock alerts.
