Best Shopify AI Sales Chatbots for Large Catalogs (2026)

The best Shopify AI sales chatbots for large catalogs sync the full catalog, understand variants and attributes, and ask follow-up questions. REP AI connects to the full catalog and is used by stores with 10,000+ SKUs, per its own site. Chatty, Zipchat, Tidio, Gorgias, Intercom Fin and Richpanel are alternatives, compared below as of 11 November 2026.

Key takeaways

• With 1,000+ SKUs, catalog sync and variant handling matter more than chat style.
• Look for follow-up questions that narrow options instead of listing 20 products.
• Search and chat should work together, not as two separate tools.
• Check product limits. Chatty's Free plan trains on 200 products and Plus on up to 20,000.
• REP AI connects to the full catalog and understands variants, bundles and attributes.
• Several vendor pages do not describe catalog depth at all. Ask for a test on your own catalog.

What matters with 1,000+ SKUs

Catalog sync

The bot must read your live catalog, including price and stock. A bot trained once on a file goes stale as soon as you change a product.

Variants and attributes

Shoppers ask about size, material, fit and color. The bot needs variant-level data so the answer matches the option they picked. Metafields and tags help here.

Bundles

Large catalogs often include bundles and kits. The bot should know what is inside and what each part costs.

Follow-up questions

With thousands of products, one answer is rarely enough. Good tools ask two or three short questions, then narrow to a few items.

Search versus chat

Search is fast for shoppers who know what they want. Chat is better for shoppers who do not. The strongest setups cover both and use live inventory.

REP AI

REP AI connects to the full product catalog and searches your live Shopify catalog in real time. It understands product variants, bundles and attributes.

The product finder and conversational search ask clarifying follow-up questions and adapt them to available inventory. REP AI's own site says it is used by stores with 10,000+ SKUs.

It runs on web chat, email, Instagram, Facebook Messenger and WhatsApp, and hands off to Gorgias, Zendesk, Kustomer, Freshdesk and Richpanel. For up to 3,000 monthly sessions, Sales is $39 a month ($29 billed annually) and Concierge is $46 ($37 annually). A 14-day free trial needs no credit card. See the Sales Agent page and pricing.
