WHY CONNECT IT

Built on live demand

The keywords come from real Amazon and Google search data pulled during the writing step - the same sources the expensive keyword suites sell.

Current rules built in

Character limits, bullet rules and image requirements are checked before you paste into Seller Central; you still verify the current category rules.

Photos and video in the same chat

The same connection generates the white-background main image, lifestyle scenes and an 8-second spot - ask for the full media kit.

PASTE THIS TO START

Write my Amazon listing for this product: <describe it>. Pull real keyword demand first, show me the keywords you chose, then give me the full listing with title, five bullets, description and backend keywords.

Questions

How is this better than asking ChatGPT alone?

ChatGPT on its own writes plausible copy from memory. Connected to Optimlister it works from live keyword volumes, real marketplace rules and your saved catalog - and it can generate the photos and video too. The output is a listing built on data, not vibes.

Does this cost extra on top of ChatGPT?

The MCP server and API key come with every Optimlister plan, including Free. Tool calls price exactly like the site: listings use your monthly listings, photos and video use credits at the same rates, and free tools stay free.

Is this official MCP?

Yes - Optimlister runs a standard MCP (Model Context Protocol) server over HTTP, the same open standard ChatGPT uses for all its connectors. One URL, one key, no extension to install.

Can it check where my listing ranks?

Yes - ask it to run a rank check for your keyword and marketplace, and to re-check after you publish. Rank checks are part of every plan.

See it work

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

Give it what you have

A listing, a link, a photo, a product name, or the email a marketplace just sent you.

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.

You publish; it keeps watching

Files, exact fields or one-click fill; then daily rank, price and listing-health watch.

One product, six listingsExample · bamboo cutting board · 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.
