Osello gets your products listed on marketplaces like Target+, Macy's, Nordstrom, and BestBuy — and keeps those listings accurate — with AI doing the heavy lifting. Instead of filling in spreadsheet templates or managing mapping rules, you connect your store, pick a marketplace, and let Osello transform your product data to meet each marketplace's requirements.
The core ideas
Four terms show up everywhere in Osello. Here's what each one means:
Products
Your products are the source of truth: the titles, descriptions, images, prices, and variants that come from your store (for example, your Shopify catalog). Osello imports this data and keeps it in sync — it never edits your source data.
Marketplaces
A marketplace is a retail channel you sell on — Target+, Macy's, Bloomingdale's, Nordstrom, BestBuy, and more. Each marketplace has its own rules: its own categories, its own required fields, and its own quirks. Meeting those rules is the hard part of marketplace selling, and it's exactly what Osello automates.
Listings
A listing is your product as it exists on one specific marketplace. One product can have many listings — one per marketplace — and each listing carries the marketplace-specific data that marketplace demands. When your product changes, Osello can update every related listing automatically.
Prompts
Prompts are AI tasks that fill in listing fields for you. Point a Prompt at the fields you need filled — size charts, materials, style attributes, category-specific details — and Osello's AI completes them from your product data, scoring its own confidence so you know what to trust and what to review.
How it fits together
- Connect your store. Osello imports your products, images, inventory, and prices.
- Connect a marketplace. Osello pulls in that marketplace's categories and field requirements.
- Create listings. Pick the products you want to sell and Osello builds a listing for each one.
- Let AI fill the gaps. Prompts complete the marketplace-specific fields your source data doesn't have.
- Submit. Osello sends your listings to the marketplace and tracks their approval status.
- Stay in sync. Inventory, prices, orders, and product changes flow automatically after that.
