How it is charged

Writing tools spend your monthly listings. Photo and video tools use credits, because they cost real money to generate. Calculators, exports and checkers are free and always will be. Every tool says what it costs before you run it, and nothing is charged if it fails.

See it work

Three steps, and what each one actually produces - words, pictures and video.

1
Give it what you have
A listing, a link, a photo, a product name, or the email a marketplace just sent you.
2
It writes, draws and checks, per marketplace
Six different listings and the images to go with them, each to that marketplace's limits and rules, with measured keywords behind the words.
3
You publish; it keeps watching
Files, exact fields or one-click fill; then daily rank, price and listing-health watch.
One product, six listingsExample · kids insulated bottle · pictures made by Optimlister
Why each version differs: every card is written fresh to the rule printed on it - Amazon now uses a 75-character Item name plus 125-character Item Highlights and benefit bullets, Etsy uses buyer-friendly titles and up to 13 tags, eBay uses item specifics, and Walmart uses structured attributes. The meter under each title shows how much of that marketplace's title limit the example uses. Every asset here is a real generator output with its exact cost - see the receipts.
