an AI agent for fashion brands.
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 fashion brand, that means an agent trained on your catalog, your size guide and your brand voice — one that resolves the size question, handles the exchange and recovers the cart, all in the same chat the customer already opened.
Size and stock queries, even from a photo
The most repeated question in fashion isn't "how much" — it's "will this fit me?" Steff answers with the real stock from your connected catalog (Shopify, WooCommerce or TiendaNube), and thanks to vision, it can read a photo a customer sends — of the garment, of a size that fit well from another brand, of a prior purchase receipt — and cross-reference it against the size guide loaded into the agent's knowledge base. Fewer "I don't know what size to order" moments turning into an abandoned cart.
Automated exchanges and returns
The agent follows your exchange policy exactly as you defined it: confirms the reason, offers an alternative size or color, generates the return instructions — all inside the WhatsApp or Instagram conversation. When a case doesn't fit the rules — a damaged garment, a sensitive complaint — Steff escalates to your human team by rules and keywords, with full context, and pauses itself so it doesn't step on the human reply.
Cart recovery with visual cross-sell
If a customer adds to cart and doesn't check out, heysteff triggers automated abandoned cart recovery (Shopify) with a message that's more than a reminder: the agent can suggest pieces that pair well with what's already in the cart, pulling that suggestion from the connected catalog itself. The goal isn't only closing the sale that stalled — it's lifting the ticket with a relevant "pairs well with" suggestion.
Season-drop campaigns with opt-in
New collection launch, end-of-season markdown, last units of a color: with the visual flow builder you set up the campaign once and it fires automatically when the trigger matches. On Pro and Max, outbound campaigns are unlimited, so you're not choosing between launching a new collection and following up on an abandoned cart the same month — and every outreach respects the opt-in and unsubscribe rules customers set.
How it connects
For Shopify, the connection is direct OAuth from the heysteff dashboard, no theme edits required. WooCommerce and TiendaNube are also native integrations. If your catalog lives somewhere else, the custom tool builder connects heysteff to any system that exposes an HTTP API or webhooks.
FAQ
Can the agent recommend a size from a photo?
Yes. Steff has vision: if a customer sends a photo of the garment, or of a size guide from another brand, the agent reads it and cross-checks it against your own size guide loaded into the agent's knowledge base to answer with the equivalent size.
Does it connect to my fashion store on Shopify, WooCommerce or TiendaNube?
Yes, those are native integrations. The agent checks stock, prices and order status in real time, and if you're on Shopify it also recovers abandoned carts automatically.
Can it handle a size or color exchange without a person involved?
Within the rules you define, yes, end to end. If a case falls outside those rules — a damaged garment, a policy exception — Steff escalates to your human team automatically, with the full conversation history.
