Amazon, Etsy, eBay, Walmart, Shopify and TikTok Shop each get their own words, fields and checks. Your assets remain yours to use anywhere.
Real numbers from a real run - the tool hands its best keyword to the next tool by itself. Nothing on this site is a mock-up.

Not on a marketplace? It still works for you.
The listing, photos and video you make here are yours to use anywhere you sell — your own site on Shopify, Wix, Squarespace or WooCommerce, your socials, a wholesale line sheet, or a page you hand to a buyer. Write it once against real marketplace rules and market data, then take it wherever your customers are.
Every listing as plain text, Markdown or CSV, plus your images — paste it straight into your own store, a blog, or an email. No marketplace required.
One clean, branded page — save it as a PDF for your own site, a wholesale buyer, or a catalog.
Export everything you have written as one CSV — your work stays yours, portable to any platform, any time.
Every other cross-listing tool moves the same words to the next marketplace and trims them to fit. We write a different listing for each one, in that marketplace's voice, to its character limits and its required fields. An Etsy listing should not land on Walmart still sounding like Etsy.
Amazon will not warn you. It suppresses the listing weeks later and asks for a plan of action. We read what is in the boxes and flag prohibited claims, restricted terms, missing attributes and over-length fields while they are still cheap to fix.
Live search volumes for Amazon and Google - the same demand data the expensive Amazon-only suites sell - and rank tracking that rechecks your keywords daily and emails you when one drops. Measured, not guessed. See the data tools.
Not sure which of those you need? Answer three questions and we will tell you which tools, in what order, and why. No account needed.
Not 71 apps. One team.
The stack most sellers run today - a copywriting app, an Amazon keyword suite, an Etsy SEO tool, a price tracker, a photo editor - is five logins, five bills, and five strangers to the same product. Every insight dies at the edge of the app that produced it. You are the integration layer. Here, one result hands its data to the next tool by itself:
One identity, one data spine, one direction: every tool ends by opening the next door. A tool that finishes and opens the next door is a step. A tool that finishes and stops is an app.
No single tool here is the point - anyone can build a tool. What you join is 71 of them that already know each other.
Ready for each marketplace
Six marketplaces, each written in its own format and against its own rules. Review the result, export the file or copy the exact fields, then publish in the marketplace. Nothing goes live until you confirm it there.
Each marketplace has its own page - its own limits, its own policy checks, its own route.
Copy and download work without the optional browser extension. Direct integrations stay gated until their approvals and launch validation are complete.
Or skip the pasting entirely. The browser extension can assist with supported marketplace forms after you review the draft. It is optional; you still confirm Publish in the marketplace.
Free tools, no card required
Every account gets working tools on day one — even the free plan.
A brutal AI critique of any listing, scored out of 100 — with a public share page. Free every day.
AI feedback on your product photos before buyers judge them. Free every day.
Real marketplace fees and margins across Amazon, Etsy, eBay, Walmart, Shopify, and TikTok Shop.
Take your listings anywhere — clean CSV and JSON exports, always yours.
Pre-sized image exports for all six supported marketplaces in one click.
Find near-duplicates in your vault before you list the same thing twice.
