About Listaza

AI-powered listing generator for resellers, thrifters, and vintage sellers.

What Listaza does

Listaza turns a single photo into ready-to-post marketplace listings for eBay, Facebook Marketplace, Etsy, Poshmark, and Mercari. Upload or capture a photo of any item, and Listaza uses AI to analyze it and generate an optimized title, description, and pricing range — formatted specifically for each platform's requirements and audience.

Who it's for

Online resellers, thrift store flippers, vintage sellers, estate sale shoppers, and anyone who regularly lists items for sale on eBay, Facebook Marketplace, Etsy, Poshmark, or Mercari. Listaza is built for people who sell secondhand goods online and want to save time writing descriptions, researching prices, and formatting listings for each platform.

Core capabilities

  • AI photo analysis — uses GPT-5.4 nano (Free/Pro) or GPT-5.4 (Premium) with Vision to identify items and generate listing copy from a single photo
  • Platform-specific output — marketplace-appropriate formatting and tone for each supported platform
  • Real-time market pricing — pulled from real, comparable active eBay listings (not AI estimates), surfaced as a low / average / high price range
  • Confidence scoring — each listing includes a score indicating how well the AI identified the item from the photo
  • AI background removal — automatically cleans up photo backgrounds for cleaner listing images
  • Batch mode — processes up to 25 items at once (Pro and Premium plans)
  • One-click copy and CSV export — for quick posting and record-keeping

Joe, founder of Listaza

Hi, I'm Joe. I turn messy, ambiguous operations into standardized playbooks other people can actually run, and Listaza started as one I built for myself. I built it after moving to a smaller apartment and spending hours writing listings by hand. Listaza is part of AstraNex Ventures. If you have feedback, I read every message.
