REP AI vs Shopify Inbox: Which Is Better for Shopify in 2026?

Which is better for Shopify, REP AI or Shopify Inbox? Shopify Inbox is free, made by Shopify and enough for many small stores that need chat on their online store. REP AI is a paid option for brands that want proactive selling, support automation, channels beyond the store chat and revenue reporting.

Last updated November 6, 2026. We read Shopify Inbox's App Store listing and Shopify Help Center pages, and REP AI's live pages and listing, on that date.

What are REP AI and Shopify Inbox?

Both put an AI agent in your store chat. One is a free Shopify app, and the other is a paid platform built around conversion and support.

What is Shopify Inbox?

Shopify Inbox is Shopify's own chat app. Its listing is titled an AI sales associate that knows your customers, and it is free. Shoppers chat from your online store, and your team replies from Inbox on the web, iOS or Android. The optional Inbox agent uses your catalog, policies, pages and knowledge base to answer questions, recommend products and add them to the cart. It needs an active online store on a Basic, Grow, Advanced or Shopify Plus plan.

What is REP AI?

REP AI is a conversational commerce platform for Shopify brands. It combines an AI sales agent, AI support and a shared inbox. REP AI is SOC 2 Type II certified and lists 35+ integrations, including Shopify, Gorgias, Zendesk, Klaviyo and HubSpot.

How do REP AI and Shopify Inbox compare side by side?

The table uses REP AI's live product pages and listing, plus Shopify's App Store listing and Help Center, as read on November 6, 2026.

When is Shopify Inbox enough?

More often than a vendor like us might like to admit. Shopify Inbox is enough if your shoppers mostly chat on your online store, you want an AI agent that answers product and policy questions and can add items to the cart, your own team can reply during the day, and you do not need email, Instagram or WhatsApp automation. It costs nothing, it comes from Shopify and its listing is rated 4.6 from 5,817 reviews. If that describes your store, start there and revisit the question when you outgrow it.

How do they compare on sales?

Both can recommend products and add them to the cart. The gap is in how a conversation starts and how results are measured.

Proactive engagement

REP AI watches behavioral signals such as hesitation, comparison behavior and disengagement. It opens a conversation only when thresholds you configure are met, not on timers or blanket popups. Shopify Inbox lists greetings and chat buttons. The pages we reviewed do not describe outreach triggered by shopper behavior, so a shopper who never opens the chat may never hear from the agent.

Product recommendations, cart and discounts

Shopify's Help Center says the Inbox agent suggests products from what a shopper is looking for, can use sizes and purchase history when available, and can add recommended products to the cart. Staff can share discount codes, and the listing lists discounts among automated responses. REP AI answers objections, narrows options and recommends complementary items from the live catalog, and shoppers can also remove items or change quantities in the chat. It offers a discount code only in the moments you define.

Revenue attribution

The Inbox listing mentions built-in analytics and buyer ratings of chats. The pages we reviewed do not describe revenue attribution. REP AI reports AI-attributed conversion tracking and counts a sale only within 24 hours of the conversation, which keeps the numbers conservative. Our sales agent page explains how REP AI does it.

How do they compare on support automation?

The Inbox agent answers questions about product details, availability and pricing, and can check an order's status after the customer signs in. Complex or sensitive conversations go to staff. If no one is available to take the handoff, the agent shows your sender email address, and the customer has to start the email, because the agent cannot send one. You can set it to handle all conversations, only chats outside your staff's availability hours, or never.

REP AI confirms the order with two details, then gives the live status, carrier, last scan and tracking link. It starts returns and exchanges under your policy, including through apps like Loop, and updates the address on orders that have not shipped. With Recharge it can skip a delivery or change a subscription after the shopper says yes. Each action has its own switch, and guardrails block sensitive topics such as medical, political and regulatory ones.

Which channels does each tool cover?

This is the biggest practical difference. Shopify's Help Center says the Inbox agent only operates within your online store's chat widget. It also says that after a shopper leaves, a reply reaches them by email only if they gave an email address or signed in. REP AI covers web chat, email, Instagram, Facebook and WhatsApp on one shared knowledge base, bills AI answers on email, Instagram, Facebook and WhatsApp at $0.75 per AI-resolved conversation, and shows shoppers' photos, voice notes and videos in the conversation.

How do the helpdesk and human handoff differ?

Shopify Inbox is a chat inbox, not a ticketing system. When staff are available, the conversation moves to the Unassigned folder with the agent's context and staff get a notification. Conversations can be open or closed.

REP AI works two ways. It has its own inbox, Rep Inbox, and it hands conversations off with full history to Gorgias, Zendesk, Freshdesk, Kustomer, Salesforce Service Cloud or Help Scout. That suits brands that already run a helpdesk. If a full helpdesk is your bigger decision, see our REP AI vs Gorgias comparison.

How hard is setup for each tool?

Shopify lists five steps: install Inbox from the Shopify App Store, add the chat widget to your online store, set chat appearance, set Inbox settings, and optionally turn on the Inbox agent. The agent does not work with legacy customer accounts. REP AI's support page says most brands connect Shopify and their help center and go live within minutes.

How does pricing compare?

How does REP AI pricing work?

REP AI plans are priced by your store's monthly website sessions. Sales starts at $12 per month for up to 3,000 sessions. Support starts at $49 per month and Concierge, which combines both, at $130 per month, each for up to 10,000 sessions. Yearly billing costs 20% less. Website AI is not metered by resolutions. Email, Instagram, Facebook Messenger and WhatsApp are billed at $0.75 per AI-resolved conversation. Rep Inbox starts at $8 per month for 50 tickets, plus $20 per agent per month, on a paid plan. Stores above 500,000 sessions get custom pricing. Every plan includes a 14-day free trial, and no credit card is required. See the pricing page for current plans.

How does Shopify Inbox pricing work?

Shopify Inbox is free. As listed on its Shopify App Store page on November 6, 2026, there is no charge and the page states no usage limits. A free tool still has a cost: your team's time to reply, and any sales missed outside store chat. If you pay for a tool, make sure it brings measurable revenue or saves measurable hours.
