Three capabilities that change the economics of listing — not just incremental improvements.
Point camera at barcode. Henry resolves brand, model, category, size, color, MSRP, and recent sold comps. No typing. No searching. Works on clothing tags, shoe boxes, electronics.
One flat-lay or hanger photo → front, side, and back model views. Clean white background. Ghost mannequin effect. Converts 40% better than flat lays on Poshmark and eBay.
Install from browser to home screen. Works offline for drafts. Camera integration for barcode scanning and photo capture. Syncs to desktop dashboard instantly.
When to choose each tool — and when to switch to Henry.
Real feedback from sellers who moved from Vendoo, Closo, and manual listing.
★★★★★"The UPC scan alone saved me 2 hours on a 50-item sneaker lot. Scan → draft → publish. Used to take me 15 minutes per shoe."
★★★★★"Virtual model angles on Poshmark are a game changer. My flat lays got 2 likes; model shots get 15+ and sell in days not weeks."
★★★★★"Switched from Vendoo. Henry's AI writes better titles for eBay Cassini. My impressions jumped 35% first week. Plus no browser automation = no account risk."
