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

Which is better for Shopify, REP AI or Manifest AI? It depends on how you want to buy and run an AI agent. Manifest AI suits brands that want a configurable agent platform with quizzes, A/B testing and a dedicated expert, with pricing set after a demo. REP AI suits Shopify brands that want self-serve setup and public, session-based pricing.

Last updated November 6, 2026. We read Manifest AI's site at getmanifest.ai, its Shopify App Store listing and REP AI's live pages on that date.

What are REP AI and Manifest AI?

Both tools put an AI agent on your Shopify store. They differ in how much you configure yourself and how you buy.

What is Manifest AI?

Manifest AI describes its product as a platform for building AI agents that handle ecommerce support and marketing. Its site cites 500+ brands and lists Shopify, WooCommerce and BigCommerce. Its Shopify listing, titled Manifest AI Chatbot and Agents, describes a ChatGPT powered chatbot for live chat, quizzes, recommendations and a shopping assistant. You set instructions, guardrails and tool calling, and you can add a custom tool.

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 Manifest AI compare side by side?

The table uses REP AI's live product pages, Manifest AI's own pages and both Shopify App Store listings as read on November 6, 2026.

How do they compare on sales?

Both tools recommend products and try to lift conversion. The difference is how a conversation starts and how much you build yourself.

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. Manifest AI lists Agentic Conversation Starters, which suggest questions based on a shopper's purchase history, plus nudges and embeds. Its pages give no further detail on proactive outreach, so ask for a demo on your own product pages.

Product recommendations and cart

Both recommend from your catalog. Manifest AI adds a Fit Predictor agent for sizing, a Product Trivia agent and AI-powered quizzes, and it can A/B test quizzes, embeds and product page widgets. REP AI answers objections, narrows options and recommends complementary items from the live catalog, and shoppers add, remove and change quantities inside the chat. It offers a discount code only in the moments you define. Manifest AI's pages do not describe adding to the cart in chat.

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. Manifest AI's site cites vendor-reported results, including a 30% uptick in add to carts and 10x ROI, and its listing lists conversion and funnel analytics. Those are Manifest AI's figures, and the pages we reviewed do not state an attribution window. If revenue proof matters, ask each vendor how they count a sale. Our sales agent page explains how REP AI does it.

How do they compare on support automation?

Manifest AI says its agents resolve order status, returns and support questions, and hand off what they cannot answer with a tag that says why. You control instructions and guardrails, and you can add custom tools for actions. Its site claims 98% ticket resolution, which is Manifest AI's own figure.

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?

Manifest AI lists website chat, WhatsApp, Instagram, email and voice calling, all running the same agent. REP AI covers web chat, email, Instagram, Facebook and WhatsApp on one shared knowledge base. If you need voice calling, Manifest AI lists it and REP AI does not. REP AI also bills AI answers on email, Instagram, Facebook and WhatsApp at $0.75 per AI-resolved conversation. Check that the channels you use are connected on the plan you pick.

How do the helpdesk and human handoff differ?

Manifest AI describes handoff to your existing helpdesk, email, live chat or WhatsApp, and does not describe a helpdesk of its own. Its listing includes live chat features such as chat assignment and business hours.

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?

Manifest AI says you install the app, let it sync your catalog, descriptions and store pages such as policies and FAQs, add more through its Data Sources tab, and test privately before publishing. Its Shopify listing also lists a dedicated AI expert. REP AI's support page says most brands connect Shopify and their help center and go live within minutes. Both offer a trial, so the practical test is to install each one and ask real shopper questions.

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 Manifest AI pricing work?

Manifest AI's site, as read on November 6, 2026, shows no prices and points to a demo or an agent request. It names three in-house model tiers, Lite, Pro and Ultra, without costs. Its Shopify listing has one plan, free to install, with a note that additional charges may apply, and a minimum 30-day free trial. We could not find what drives the bill, so ask for a written quote that says so.

The difference to plan for: Manifest AI's price is set with the vendor, while REP AI's is public and grows with store traffic and resolved messaging conversations.

Who should choose REP AI and who should choose Manifest AI?

Manifest AI is a good fit if
