Chat-first shopping experience
Customers can chat with your store inside ChatGPT to discover products, policies, and FAQs naturally — no searching through menus.
Built for agentic commerce
Your Custom GPT follows your instructions, proactively guiding customers, upselling, and preparing carts instead of just answering questions.
No GEO required
Each Custom GPT is a direct chat with your store only. Your products are always top-ranked in the conversation by design.
Why Custom GPT over Shopify's Agentic Storefront?
Shopify recently introduced Agentic Storefronts, allowing stores to sell through ChatGPT directly. While this sounds promising, there are significant trade-offs that make Custom GPT a better approach for most merchants.
Agentic Storefront
- ✗4% commission on every sale — cuts into already tight margins
- ✗No customer data — you get a sale, but lose the lead. No email, no retargeting, no relationship building
- ✗Limited control — no upselling, no custom flows, no brand experience. It's a product catalog, not your store
- ✗Relies entirely on discoverability — if customers don't find you organically in ChatGPT, you get zero traffic
- ✗Brand risk — poor service or mistakes reflect directly on your brand, with increased chargebacks and refund disputes
Custom GPT with Mirach
- ✓Flat monthly subscription — likely less than 4% of your sales, with no variable costs
- ✓You own the customer — checkout happens on your Shopify store. Full lead capture, email collection, retargeting capabilities
- ✓Full customization — control the conversation flow, upsell strategies, brand voice, and sales process from start to finish
- ✓Multiple distribution channels — share via direct links, QR codes, or the ChatGPT marketplace. You control access
- ✓ChatGPT guides the sale on your terms — the AI works for you, not as a neutral marketplace mediator
Bottom line: Agentic Storefronts may generate incremental sales in high-traffic categories, but you sacrifice customer ownership, margin, and brand control. Custom GPT gives you the same conversational commerce capabilities while keeping you in control of the experience — and the customer relationship.
Modern stores often sell products that need context: backstories, explanations, comparisons, or usage guides. Traditional storefront search and navigation aren't designed for that.
With Mirach GPT, your store becomes a conversational interface inside ChatGPT. Customers ask questions in plain language, get accurate answers based on your catalog and policies, and can immediately move to checkout when they're ready.
This approach removes friction, reduces drop-offs, and opens a new distribution channel without relying on SEO, ads, or marketplace competition.
