Restok
Back-in-stock alerts with an AI widget builder and a drag-simple email builder
Overview
Restok is a back-in-stock notification app for Shopify that turns out-of-stock moments into recovered sales. When a product sells out, Restok adds a “Notify me when available” button to your product pages so shoppers can join a waitlist in one tap.
What sets Restok apart is design made effortless. An AI widget builder styles your Notify Me button to match your store — describe the vibe and it writes the copy and picks the colours — while a full email builder lets you craft restock emails from ready-made templates, complete with an AI copywriter that can write and even translate the message for you.
The moment you restock, Restok automatically emails everyone who was waiting — bringing customers back to buy and recovering revenue you would otherwise lose. It installs in minutes, needs no code, and comes with a genuinely useful free plan.
Bring shoppers back the moment sold-out items return to stock.
Restocks are detected and emails sent automatically — zero manual work.
No code and no theme edits. Install, match your theme, done.
