Swiftlisted AI

Swiftlisted turns photos of second-hand stock into finished listings and posts them to eBay, Depop, Vinted, Grailed, Etsy, Shopify, Poshmark, Facebook Marketplace and Whatnot. Most cross-listing tools build one listing from photos of one item. Swiftlisted takes photos of a mixed pile, works out which photos belong to which item, and hands back separate drafts in an editable grid — the difference between listing an item and clearing a haul. When something sells, it detects the sale and takes the listing down everywhere else, so the same jacket doesn't sell twice. The free plan takes no card and doesn't expire.

Verimle

Verimle is a profit-management platform for marketplace sellers who are tired of finding out at month-end that a product was losing money all along. Instead of revenue dashboards, Verimle answers one question per product, per day: what actually stayed in your pocket? It pulls commission, service fees, shipping deductions, returns and VAT straight from each marketplace's official finance services and merges them with the cost you enter, so loss-making items turn red the next morning instead of on the invoice. On Trendyol and Amazon this is real settlement and financial-event data, not an estimate. On eMAG and Etsy, profit is computed from order data and clearly labeled "estimated" in the product itself. That profit figure then does work. Floor-guarded repricing sets a per-product minimum price that protects your margin, and Verimle never drops below it — if a competitor undercuts you into a loss, it stops and warns you instead of following. Buybox and competitor prices are tracked on Trendyol, Amazon and eMAG. Products inside a marketplace campaign are skipped by default so your campaign price stays intact. Verimle also watches the money moving the other way: it compares each order's commission against that product's usual rate and the category's official rate, flags overcharges, and prepares a dispute draft for you to review and submit. It does not recover money automatically — you send the dispute. Around that core sit payout reconciliation, a cash-flow calendar, return-reason analysis, stock sync with oversell protection, AI-drafted product content and customer replies, listing quality scores, review and rating analysis, and an accounting export for VAT, withholding and commission. One panel covers Trendyol (Türkiye plus 15 international storefronts), Amazon (23 marketplaces), eMAG (Romania, Bulgaria, Hungary, Poland) and Etsy — 34 countries in total. The interface is available in 11 languages. You connect a store with the marketplace's own official method; your store password is never requested. Start free with no credit card, or try Pro free for 14 days.
