Buyers ask AI what to buy. Make your listings the answer.

Vendortune copies your eBay inventory into a storefront on your own domain and into the product feeds that ChatGPT, Google AI Mode and Gemini read. Then we keep it in sync every 15 minutes.

Your domain, your dataThe storefront and feeds are yours if you ever leave.

AI assistants can't see most of what's on eBay.

In early 2026, eBay changed its rules to keep most AI agents and bots off its site, with an exception for Google's shopping crawler. That protects the marketplace, but it also means many AI assistants never read your listings at all.

Meanwhile, AI shopping answers increasingly draw on structured product feeds that merchants submit directly. Sellers who only exist inside eBay are missing from that pipeline.

Vendortune gives your inventory a home those assistants can read, without changing how you sell on eBay.

How it works

Connect your listingsSign in with eBay, or send us a Seller Hub export. Setup takes one short call.
We build three outputsA storefront on your domain, a Google Merchant Center feed, and a ChatGPT merchant feed.
We keep them in syncEvery 15 minutes. If sync falls behind, we get an alert before your buyers notice.
You see what's workingA monthly report: which AI answers mention your items, and the clicks they send.

The buy button can link back to your eBay listing, or to checkout on your own site on the Pro plan. Either way, your eBay store keeps working exactly as it does today.

Questions sellers ask

Do I have to change anything on eBay?: No. You keep listing and selling on eBay as usual. We read your listings and publish copies to your own storefront and feeds.
What happens when something sells?: It is removed from your storefront and every feed on the next sync, within 15 minutes, so buyers aren't sent to items you no longer have.
Will this guarantee more sales?: No one can promise what an AI assistant recommends. We guarantee the feeds are built, approved and current, and we report what they produce each month.
Who owns the domain and the feeds?: You do. If you cancel, the domain and your product data stay with you.
Do you contact my eBay buyers?: Never. We don't use eBay buyer data, and we never steer eBay buyers off eBay.
