Conversational AI for supplement 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. In supplements, most messages repeat: how to take it, what it combines with, how often to buy again. Steff answers those questions using your own knowledge base, and knows exactly when a question stops being a FAQ and needs a real person.
Usage and dosage FAQ, answered from your own knowledge
You train Steff on your brand's knowledge base — usage instructions, recommended dosage, combinations, contraindications you already publish — and the agent answers those repetitive questions instantly, in your brand's voice, without a customer waiting for someone on the team to free up. The rule that matters is the one you set: define which questions always escalate to a human or a health professional (pregnancy, medications, specific medical conditions) through escalation rules and keywords. Steff never decides that on its own — it follows exactly what you configure.
Replenishment reminders before the product runs out
Supplements are consumed in cycles: a bottle lasts weeks, not one-off purchases. With heysteff's visual automation flow builder you set up a scheduled reminder that reaches the customer before their product runs out, so the reorder happens on its own instead of depending on someone remembering to write to them.
Label reading from a photo
Steff has vision: it can read images a customer sends on WhatsApp or Instagram. If they send a photo of a label — yours or a competitor's — to ask something specific, the agent reads it and uses that information to answer, the same way it does with payment proofs.
Cart recovery, so the sale doesn't get lost along the way
If you sell on Shopify, heysteff automatically recovers abandoned carts: it detects when someone left products unpaid and reaches out to pick the purchase back up. It's the same logic as replenishment, applied to the moment a customer was already decided and something interrupted them. And because the reach-out happens on the same channel the customer was already using — not a generic marketing email — it reads as a follow-up from your brand, not a broadcast.
How it connects
heysteff connects to your WhatsApp Business, Instagram, Messenger, Gmail and your Shopify store. Starter-plan implementation is live the same day; Pro takes 3-7 days; Max, for operations with multiple product lines or brands, is implemented in 2-3 weeks with dedicated onboarding. Whichever plan you start on, the same knowledge base, escalation rules and reminder flows carry over as you add channels or product lines.
◆ frequently asked questions
Does Steff replace advice from a health professional?
No, and it shouldn't. Steff answers the usage and dosage questions already covered in your knowledge base, but you define which cases always escalate to a human or a health professional — for example, questions about pregnancy, drug interactions or pre-existing conditions — through escalation rules and keywords.
How do I set up replenishment reminders?
With heysteff's visual flow builder you set up a reminder that goes out before the product runs out, based on the typical consumption cycle for each line. It doesn't depend on someone remembering to send it manually.
Can it read a photo of a label a customer sends?
Yes. Steff has vision: it can read images customers send over WhatsApp or Instagram, like a photo of a label or a payment proof, and use that content to answer.
