Genstory FAQ
What do I need to start creating a story?
All you need is an idea! The process begins by typing a simple text prompt into the Genstory app or website.

Can I customize the story after it's generated?

Ninjasell FAQ
How does the AI Listing Builder work?
The AI Listing Builder works by performing real-time analysis of current best-selling products on Etsy that are similar to your design. It scans and deconstructs hundreds of successful listings to understand the winning patterns in titles, tags, descriptions, and even visual styles. It then applies these data-backed insights to your specific product, generating a complete, optimized listing tailored to attract buyers and rank well in Etsy search.
What is included in the White-Label Fulfillment service?
Ninjasell's White-Label Fulfillment is a hands-off service where we handle the entire order process for you. When a customer buys your product, we manage the printing on high-quality items (like t-shirts, mugs, sweatshirts, and candles), the packaging, and the shipping. Crucially, the entire process is unbranded—there is no Ninjasell logo or mention on any packaging or shipping materials, so the customer experience is fully branded as your own store.
Does the Pinterest Auto-Poster require constant management?
No, the Pinterest Auto-Poster is designed for complete hands-free operation. Once you connect your Pinterest account and set up your preferences, Ninjasell automatically publishes your new Etsy listings to the high-traffic boards you've selected. It also generates SEO-optimized descriptions for each pin. This means your catalog markets itself continuously, driving organic traffic to your Etsy shop without you needing to manually create or schedule pins.
What happens when ReSpark revives a listing?
When ReSpark identifies a listing with no sales for 90+ days, it automatically initiates a revival process. First, it analyzes current Etsy trends and high-intent search data. Then, it regenerates the listing's title and tags with fresh, trend-driven keywords to improve its search visibility and appeal. Your original design, description, and price remain unchanged, but the listing's SEO core is updated to give it a new chance to be discovered and sold, all without any action required from you.
