I got tired of writing the same listing four times, so I built a thing. Wondering if I'm the only one.
Background: I sell on Merch, TeePublic, and Etsy via Printify. Every design meant writing a Merch listing (brand/feature bullets, 2000 char limit), a TeePublic listing (different tag logic), and an Etsy listing (front-loaded title, 13 tags, structured description). Same design, four sets of rules, an hour of my life each time.
So I built a Chrome extension that does all of it from one panel. Upload the design, it reads the image, pulls ranked keywords, and generates the listing for each platform in that platform's format.
The part I actually use most: it connects to my Etsy shop and looks at what actually sold, then regenerates listings off my real winners instead of guessing. My best seller last year did 886 units and I've been mining it ever since.
I've been running it privately for about a year, it's on version 2.49, and it's stable enough that I'm wondering whether other people would want it.
Not selling anything today, I don't even have a landing page. Just want to know if this is a me problem or an everybody problem. If you'd use it, say so and I'll follow up when it's ready.
Happy to answer anything about how it works.
