Built by a seller, for sellers.

It started with a problem I knew firsthand.

As an Etsy and Shopify seller, I found myself spending far more time creating product listings than creating products.

Every new listing meant researching keywords, learning marketplace requirements, writing descriptions, choosing tags, and trying to understand what would help the product get discovered.

Selling on more than one marketplace created even more work. Each platform had different fields, formatting preferences, character limits, and search requirements, so the same product had to be rewritten multiple times.

Even using general AI tools did not fully solve the problem. I still had to write detailed prompts, explain the marketplace requirements, request the correct number of tags, adjust the tone, check the character limits, and edit the results before publishing.

With ListSage, sellers can describe a product, upload photos, or paste an existing listing URL. ListSage gathers any important missing details, handles the research and marketplace requirements, and creates complete, ready-to-post listings for every selected marketplace.

Titles, descriptions, keywords, tags, and other required fields are tailored to each platform while maintaining the seller's brand voice across every version.

Every feature in ListSage was created to solve a real problem I experienced while running my own ecommerce business. The goal has always been simple: give sellers back the hours they lose to research, prompting, formatting, and rewriting.
