the AI agent built for Shopify stores.
heysteff is an AI platform for customer support and sales across WhatsApp, Instagram, Messenger, Gmail and Shopify; Steff is the AI agent that runs it. For a Shopify store, that means connecting your catalog and your orders in minutes, with no engineering work, and letting the agent answer customers, sell and recover abandoned carts without your team chasing every shopper by hand.
Connects by OAuth — no theme edits required
You connect your store from the heysteff dashboard through Shopify's official authorization flow (OAuth): grant access, and heysteff starts reading your catalog, your orders and your abandoned checkouts in real time. There's nothing to install from the Shopify App Store for the core agent, and not a single line of your theme needs to change. It's built so a store owner with zero technical background can finish the whole setup alone.
heysteff core vs. heysteff Reviews — two different installs
These are two different products, installed two different ways. heysteff (the support and sales agent this page is about) connects by direct OAuth, outside the App Store. heysteff Reviews is a separate app, installable from the Shopify App Store, built for requesting and displaying product reviews by conversing over WhatsApp or email after each purchase. You can run either one on its own, or both together.
Automatic abandoned-cart recovery
When a customer adds items to their cart and doesn't check out, heysteff fires an automatic follow-up over WhatsApp or email to bring them back to checkout — without anyone on your team manually combing through Shopify's abandoned-checkout report. AI-driven follow-up tends to multiply cart recovery by an average of 4.2x compared to no active follow-up; the methodology behind that figure is documented at /metodologia.
Real-time inventory and order status
The agent checks stock, variants and order status directly against your connected store, so a customer asking "do you have this in size M, black?" or "where's my order?" gets an exact answer without a human opening the Shopify admin to look it up. If the data changes — stock runs out, an order ships — the agent's next answer reflects it.
heysteff Reviews for your storefront
heysteff Reviews requests reviews by conversing over WhatsApp or email after fulfillment, instead of a web form — the customer replies with a rating, text, photo and video right inside the chat. It ships with moderation, a full suite of storefront widgets for the theme editor (star badge, photo wall, carousel, all-reviews page), SEO rich snippets and funnel analytics. It's a separate Shopify App Store listing, with a 7-day free trial on any plan.
Pricing for Shopify stores
Shopify cart recovery requires Pro or Max. Pro — 299 USD/month, the most popular: 1 Shopify store with abandoned-cart recovery, 3,000 conversations/month, 4 channels, 8 users, unlimited outbound campaigns.

Pro goes live in 3-7 days; Max in 2-3 weeks with dedicated onboarding.
FAQ
Is heysteff a Shopify App Store app?
The heysteff core agent (support, sales, cart recovery) connects to your store by direct OAuth from the heysteff dashboard — no install from the Shopify App Store, no theme edits. heysteff Reviews, on the other hand, is a separate app installed from the Shopify App Store for managing product reviews.
How many Shopify stores can I connect?
The Pro plan (299 USD/month) includes 1 Shopify store with abandoned-cart recovery. The Max plan (549 USD/month) includes 3 Shopify stores, built for multi-brand operations. The Starter plan does not include Shopify cart recovery.
Is checkout generated inside the chat?
The agent talks the customer through products, stock and order status, and hands them a checkout link inside the conversation; payment is completed on your Shopify checkout, not inside the chat itself.
Does it also work with WooCommerce or TiendaNube?
Yes, WooCommerce and TiendaNube are native heysteff integrations, alongside HubSpot and Defontana. Automatic abandoned-cart recovery is a Shopify-specific feature; on other platforms the agent still answers, sells and books appointments the same way.
