AI Shopping Assistants for Shopify Plus and High-Traffic Stores (2026)

For Shopify Plus and other high-traffic Shopify stores, the main options in 2026 are BOBBI Smart Store, Rep AI, Dialog, Zipchat and iAdvize. BOBBI Smart Store turns the storefront itself into a conversation and runs next to your theme. Rep AI and Dialog add an AI sales assistant priced by monthly visitors, Zipchat is priced by AI replies and covers chat, email and social channels, and iAdvize is priced by conversations with onboarding help on larger plans. Once a store has tens of thousands of visitors a month, the pricing model and how safely you can roll a tool out matter as much as the AI itself.

Disclosure: this comparison is published by BOBBI Oy, the maker of BOBBI Smart Store, which is listed first. The other apps are described from their official Shopify App Store listings, checked on 6 October 2026. Prices are list prices in USD; ask each vendor about annual and custom plans.

What changes when a store has tens of thousands of visitors a month

• Cost follows your traffic or your chats. Visitor-priced tools cost $368 (Rep AI) to $399 (Dialog) a month at 50,000 visitors and more above that; reply- and conversation-priced tools (Zipchat, iAdvize) cost more as more shoppers chat.
• Catalog limits start to matter. Rep AI's Standard plan covers up to 5,000 products and iAdvize's plans are capped at 1,000, 10,000 or 50,000 SKUs, so check the limit against your catalog.
• Every wrong answer costs more. On a busy store, an assistant that invents a size, price or stock level does real damage, so test it with your hardest product questions before it goes live.
• Rollout needs control. Start with part of your traffic, keep each shopper on one version and compare against your current store before you scale up.

How to evaluate an AI shopping assistant on a high-traffic store

• Accuracy: ask it your 20 hardest product questions; answers should come from your own catalog, with real prices and stock.
• Checkout: shoppers should pay in your native Shopify checkout, so your checkout customizations, payment methods and fraud tools keep working.
• Rollout: start with a share of visitors, keep each shopper on the same version and compare revenue per visitor, conversion rate and average order value with your current store over the same weeks.
• Pricing model: estimate the monthly cost at your real visitor and conversation volumes, including peak months such as Black Friday.
• Data and compliance: where data is hosted, GDPR and a data processing agreement, which store permissions the app requests, and the list of sub-processors.
• Catalog fit: product or SKU limits, and the languages and markets you sell in.

The options, one by one

1. BOBBI Smart Store — best when the storefront itself should sell

BOBBI turns your Shopify catalog into a Smart Store: shoppers say what they need, tap simple choices and see the matching products, then pay in your native Shopify checkout. It runs next to your theme. In the BOBBI Portal you choose what share of visitors sees the Smart Store, and each shopper stays on the same version, so you can compare it with your current store. It is hosted in the EU and requests read-only store access. Consider that it is new (launched August 2026) and focuses on selling, not support tickets.

2. Rep AI — best for proactive sales chat plus support automation

Rep AI adds a proactive AI chat to your existing theme that recommends products and also answers support questions. It is priced by monthly visitors: $368 a month covers up to 50,000 visitors and up to 5,000 products, and each additional 1,000 visitors costs $12. Paid plans have a 14-day trial.

3. Dialog — best for an Amazon Rufus-style assistant

Dialog describes itself as an Amazon-inspired, Rufus-style shopping agent. It is priced by monthly unique visitors: $249 up to 25,000, $399 up to 50,000 and $799 up to 100,000, with a free plan of 200 conversations a month and a 14-day trial.

4. Zipchat — best for sales and support across channels

Zipchat combines an AI chatbot with live chat across your site, email, WhatsApp, Instagram and Messenger. It is priced by AI replies: $300 a month for 3,000 (about 1,250 conversations) and $600 for 6,000, with a free plan and a 7-day trial.

5. iAdvize — best for large catalogs that want onboarding help

iAdvize offers an AI shopping assistant priced by conversations and catalog size: $520 a month for 1,000 conversations and up to 10,000 SKUs, and $1,330 for 3,000 conversations and up to 50,000 SKUs, which adds onboarding with its customer success team. There is a 30-day free trial, and annual plans are 25% cheaper.

How to choose

• The storefront itself should guide every shopper, with a clean comparison against your current store: BOBBI Smart Store.
• A proactive chat on your existing theme that also answers support questions: Rep AI.
• An Amazon Rufus-style assistant with predictable visitor-based pricing: Dialog.
• Shoppers ask for help on WhatsApp, Instagram and email as well as on the site: Zipchat.
• A very large catalog and hands-on onboarding: iAdvize.
• Whatever you choose, test it on part of your traffic first and judge it by revenue per visitor.
