Steff is the AI agent that connects your store, ERP or app — via webhook or API — to WhatsApp, Instagram, Messenger and email. It answers, sells and rescues carts for you, 24/7, in your brand's voice.
Connect your ecommerce, ERP, CRM or internal app. Steff sits between your systems and your messaging channels, understands the full customer context — orders, stock, shipments, history — and replies in your tone. No IT project required.

Order status, exchanges, returns, sizing, shipping ETAs. Steff answers from your real data — never makes it up.
Detects abandonment, writes on the channel the customer used, offers the right nudge and generates checkout. No blast emails.
Upsells, cross-sells, suggests bundles and schedules follow-ups. Learns what closes in your category and season.
Upload your brand guides, sample replies, FAQs. Tune formality, warmth and humor with simple sliders.
One bay for WhatsApp, IG, Messenger and email. Your team works in parallel — conversation assignment, internal notes, labels. When someone on your team replies from the native IG app, Steff detects it and pauses itself.
One click per conversation or per channel. Steff stays quiet and hands the conversation back to you.
Rules + instinct. If it detects anger, complexity or trigger words, it opens a ticket and pings the admin on WhatsApp.
Scheduled tasks: chase overdue orders, post-purchase follow-up, sync stock, send reminders. Cron + AI, no glue code.
The customer sends a photo of a broken product or a long voice note — Steff reads the image, transcribes the audio and answers in context.
Design conversations that fire real actions in your systems. Steff hooks every step to tools — from a private API to a shell script. If your system speaks HTTP, Steff can drive it.

Steff loads history, customer profile, stock and business rules.
Picks tone, next action, which tool to run and which channel to reply on.
Creates checkout, schedules nudge, drops an internal note, calls your API or escalates.
Every outcome — sale, resolved ticket, no-show — feeds back into Steff.
No code, no cryptic prompts. Upload your material, set the tone with sliders and tell it what to do in each scenario. Steff grades itself weekly and shows you what it learned.
Connect your account and we'll process your last 5,000 conversations to clone your tone. You flag the "gold" replies, the ones to avoid, and Steff uses them as a north star.

No. Steff takes 70-90% of the repetitive load and frees your team for the cases that move the needle: VIP customers, serious complaints, big sales. You decide what always escalates.
As long as your system exposes an HTTP API (or can fire webhooks), Steff connects. We ship native integrations for Shopify, WooCommerce, BigCommerce, HubSpot and NetSuite, and a tool builder for everything else.
Yes. We help you get your verified WhatsApp Business API number with no friction. We also work with numbers you already have on another BSP (Twilio, 360dialog, Gupshup).
Very. You can pause per conversation, per channel, per workspace, or globally. And if someone on your team replies from the native Instagram or Messenger app, Steff detects the "echo" and pauses itself so it never steps on a human reply.
Yes. Servers in regions you pick, encryption in transit and at rest, no training of global models with your data. We follow GDPR and Chilean data protection law best practices.
Starter is live the same day. Growth, 3–7 days depending on integrations. Scale depends on scope — we average 2–3 weeks with dedicated onboarding.
