The discussed product is an innovative SaaS known as Smart Listing AI, designed to automate the creation of marketplace listings for resellers. The solution allows users to upload product photos, after which artificial intelligence generates the title, description, price, and category. These details are then published directly to the marketplace through an API, completing the process in about 30 seconds per listing. Smart Listing AI includes a full-stack SaaS built with Next.js 16, FastAPI, and SQLite, and features AI-driven listing generation via an advanced language model. It enables direct API publishing to major marketplaces like eBay and various European platforms, and supports automatic filling on others such as Vinted and Facebook Marketplace. Users can benefit from bulk generation capabilities, creating up to 50 listings by grouping photos. The service offers multiple pricing plans through Stripe and provides a demo without registration. Its landing pages are optimized for search engines across seven marketplaces, and it operates efficiently via a VPS. Since its launch in January 2026, the platform has generated 1,333 listings with 13 registered users. However, it currently presents zero revenue due to an intentional focus on product development over marketing efforts. There exists a significant opportunity for growth in the large, underserved reseller market, notably contrasting with existing competitors. The developer highlights superior technical capabilities, particularly in terms of marketplace coverage, at competitive pricing. A comprehensive transfer package, including documentation, a code walkthrough, and 30 days of post-sale support, is offered by the seller.
