About iWhisperer4u
AI-powered price tracking built by resellers, for resellers. We watch marketplaces 24/7 so you never miss a drop.
Live price tracking
Our bots monitor StockX, GOAT, eBay, Vinted, Leboncoin, wehaveit.fr and TCG marketplaces around the clock — refreshing prices automatically and surfacing real deals as they happen.
Independent & transparent
We are not affiliated with any marketplace or brand. We aggregate publicly available data and present it clearly, with no hidden agendas or sponsored listings.
Made for Europe
Localized for the French and European reseller scene — from EU VAT calculations to Vinted and Leboncoin coverage. One dashboard, every market that matters.
What is iWhisperer4u?
iWhisperer4u is a subscription-based SaaS that helps collectors and resellers track product prices across multiple online marketplaces. Whether you flip sneakers, trade TCG cards or hunt underpriced grails on secondhand platforms, our AI bots keep an eye on the market so you do not have to.
Paste any product URL and we watch it 24/7. When the price drops, you get an instant alert via Telegram, WhatsApp or Email. Our dashboard gives you a unified view of live deals, your personal watchlists, your sneaker collection with profit/loss tracking, and a dedicated TCG portfolio manager — all in one place.
The service is designed for speed: deals surface within minutes of a price change, and our smart retry system handles marketplace rate-limits automatically so no drop is lost to a temporary block.
iWhisperer4u is a product of THE SAAS FACTORY, a French software publisher registered in Paris. We build tools we use ourselves — and we ship updates continuously based on what the community asks for.
