the best AI agents for ecommerce in 2026.
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. This guide compares the most relevant options for a store that wants to automate support and sales with AI in 2026, with explicit criteria before naming anyone — including heysteff, which appears on this list with full transparency.
"AI agent for ecommerce" has become a label slapped on almost any tool with a chat box. The real difference between an agent that resolves and a flow with a thin AI layer is whether it can read real store data (stock, order, cart) and act on it, not just generate generic text. Before the list, here are the criteria we used to evaluate each option.
Evaluation criteria
- Channels covered. Does it handle only the website chat, or also WhatsApp, Instagram DM, Messenger and email in a single inbox?
- Real AI vs. flows with a thin AI layer. Does the agent reason with context and tools (orders, stock, history), or is it a flow tree with a text generator on top?
- Store integration. Does it read and act on Shopify/ecommerce platform data in real time, or does it only know what you taught it manually?
- Actions and tools. Can it execute actions (book an appointment, recover a cart, save a qualification data point), or does it only chat?
- Transparent pricing. Does it publish its pricing on the website, or do you have to book a call to find out what it costs?
- Free plan. Can you try it without a card before deciding?
heysteff
heysteff is a multichannel AI agent (official WhatsApp Cloud API and unofficial number via Baileys, Instagram DM, Messenger, Gmail) with direct Shopify integration: abandoned cart recovery with real order context, appointment scheduling synced to Google Calendar, lead qualification, and a tool builder over HTTP APIs/webhooks to connect any system. It includes copilot mode so the human team can take over any conversation in one click, with "echo" detection so the bot pauses itself. The LLM model is configurable per workspace (Anthropic, OpenAI, DeepSeek or OpenRouter). It has a Free plan (50 conversations/month, 1 channel, no card required) and paid plans from 149 USD/month, with no setup fee.
◆ transparency
Yes, heysteff is our tool — we include it on this list under the same criteria we apply to the others, and you can verify every claim at heysteff.com or by requesting a demo. It's the better option when you need a single agent handling WhatsApp, Instagram, Messenger and Gmail with real data from your store, not just a web chat.
Gorgias
Gorgias is a helpdesk built specifically for ecommerce, with a strong focus on email and chat integrated into ticketing and store data. It's one of the most established options for teams that already operate on a ticket model and want AI on top of that workflow. Best for: stores that already use a helpdesk/ticket model and prioritize support email and chat over messaging like WhatsApp or Instagram.
Intercom Fin
Fin is Intercom's AI agent — one of the most mature support messaging platforms on the market, historically focused on SaaS and enterprise web chat. It's a solid option for large operations that already live inside the Intercom ecosystem. Best for: SaaS or larger companies with support centered on web chat, not necessarily on social messaging or LATAM WhatsApp.
Tidio Lyro
Lyro is Tidio's AI agent, aimed at small and mid-sized stores that want an AI chat on their website without a complex implementation. It's an accessible option for businesses just starting to automate their web chat. Best for: SMBs that prioritize a simple AI chat on the website over a full multichannel inbox.
ManyChat
ManyChat is the world's most widely used tool for conversational marketing automation: visual button flows for Instagram DM, Messenger and WhatsApp, with a strong focus on broadcast and audience growth through comments and ads. Best for: brands whose priority is growth marketing and mass broadcast on social media, rather than an agent that reasons with order or stock data.

◆ in short
There is no "best" AI agent for ecommerce in the abstract — there's the one that best covers your channels, your stack and the way you sell. Compare against the criteria above, not just the most familiar name.
