# ListGuard > ListGuard is a web app for eBay UK sellers who list one item at a time (auction finds, job lots, car boot stock). It is a product by ZuniTech AI (https://zunitechai.com) and is not affiliated with eBay. ## What it does - Listing writer: 4–6 photos (item, label/model number, box/barcode, accessories) or a few words → title, item specifics, description and SKU. It asks for better photos when a label can't be read, and never invents details. - Shop health: reads eBay Seller Hub reports (active/inactive listings, orders) and finds duplicate listings, ALL-CAPS titles, health claims eBay UK removes, missing SKUs, watched-but-unsold listings, orders without tracking, low stock and unsold listings to relist. - Item specifics doctor: flags "Does Not Apply" in fields buyers filter by, values that contradict the title, the title pasted into a field, unsafe uses, expiry dates that are close, and gives the corrected value. - Title + SKU fix: one Seller Hub upload file (eBay's own template format) that revises titles and SKUs. - Results Report and eBay codes: explains eBay's upload results file in plain English, e.g. warning 23015 means the change went through. - Pricing & stock clearance: break-even price from your cost, eBay fees, postage and ads; how long stock takes to sell; the least-loss way to clear it. - Auctions: the most to bid on an eBay lot and still make your profit, and Lot Watch for eBay UK auctions (including mixed lots). ListGuard never bids for you. ## Who it's for Small UK eBay sellers and resellers, new sellers, and anyone fixing rejected Seller Hub uploads. ## Free tools - eBay error codes explained: https://listguard.zunitechai.com/ebay-error-codes - Item specifics checker: https://listguard.zunitechai.com/ebay-item-specifics-checker - eBay job lot max bid calculator: https://listguard.zunitechai.com/ebay-max-bid-calculator - eBay break-even price calculator: https://listguard.zunitechai.com/ebay-break-even-calculator - eBay listing writer from photos: https://listguard.zunitechai.com/ebay-listing-writer ## Links - App: https://listguard.zunitechai.com - Company: https://zunitechai.com
