Help customers choose
Build answers on use, compatibility, differences and limits, the details that decide a purchase.
For brands and specialty retailers whose customers need advice before they buy
Your products have
more to say than
your catalog reveals.
Querytail's AI Product Data Platform collects, structures and enriches your product data so AI can explain your products, answer your customers' questions and help them choose.

Advises customers on your site
The question behind the purchase
Will this bag fit my laptop in its sleeve?
The listed capacity doesn't answer that.
You need to know the usable space, the size of the opening and how much room the laptop takes up inside its sleeve.
Querytail finds those details so AI can answer the question your customer is actually asking.
Why it matters
Better answers, less duplicate work.
Reuse your experts' knowledge
Build product information once and reuse it across your AI tools, instead of starting over in each one.
You have the final say
Start from your catalog and decide which information each AI tool can use.
Shared knowledge
One set of approved product information, three ways to use it.
Advise customers on your site, help AI assistants like ChatGPT describe your products accurately, and bring the same answers to your teams in their AI assistants.
Brand Discovery helps when research starts in an LLM. Brand Agent takes over once the customer is on your site.
From product page to answer
Brand Agent answers customer questions on your site, using information your team approved.

How the platform works
See how the pieces work together.
Sourcing Agent gathers the information, Product Engine turns it into suggested enrichments, and your team approves, edits or rejects each one in Merchant Console.

See it in context
From one customer question to a confident choice.
See how one customer question exposes a gap in your product data, how Querytail fills it, and how the approved answer then helps customers and your teams.
Silent animation.
Ready for your IT, legal and product teams.
- Your PIM or catalog remains your source of truth, and nothing is written back to it without your approval.
- You stay in control of your brand, your product information, your customer data and your checkout.
- Your data is processed in the European Union, and your catalog and customer data are never used to train models for other companies.
How it starts.
- 01
Connect your catalog.
On Shopify, Brand Agent installs as a theme app embed. Other catalogs start from a product file we import with you.
- 02
Review what Querytail proposes.
Your team approves, edits or rejects each suggested enrichment in Merchant Console.
- 03
Go live for part of your visitors.
A control group doesn't see Brand Agent, so you can measure its effect.
