What you get
Most Amazon Merch sellers design first and research never — then wonder why nothing sells. Trendlytic flips that: one search shows what's genuinely selling in a niche across Amazon Merch (and Etsy, Redbubble, and TeePublic), so you design into proven demand instead of a crowded dead end.
AI that writes your Merch listing
Found a proven niche? The AI Studio builds the Merch listing — an AI Niche Finder for ideas, plus slogan, quote, listing and description generators formatted to Amazon's own rules and written to keep registered brands and characters out of the copy.
What's actually selling
Store-first research surfaces the proven best-sellers in a niche — real winners, not a dump of random search results you still have to vet.
Demand vs competition
See whether a Merch niche has real demand and whether it's already saturated, so you skip the dead ends before wasting a design slot.
All four marketplaces
Amazon Merch, Etsy, Redbubble, and TeePublic in one search — spot a niche winning on one platform that's wide open on another.
Keyword-ready output
Pair it with the free Amazon Merch keyword generator to turn a validated niche into title, brand, and bullet keywords.
A listing that won't trip Merch's content policy
The generator writes to Amazon's actual rules: keyword phrases capped at twenty characters, a title that reads like a sentence instead of a comma pile, and none of the product, fulfilment or review-solicitation language that gets listings blocked. You get a slogan and an image prompt for your own design, not a copy of someone else's.
Inside the app
See it working
Discover niches across every marketplace
Search any niche and Trendlytic scans Amazon Merch, TeePublic, Redbubble, and Etsy at once — with a live Trending Now feed per marketplace, so you spot what's heating up on Amazon before it's saturated.
See the designs actually selling
Store-first research pulls the proven best-sellers in a niche — so you study real winners and the angles that work, not a random page of search results you still have to vet.
Get the keywords winners actually use
Pull the phrases top designs rank on across Amazon Merch, Etsy, Redbubble, and TeePublic, each rated for demand, competition, and opportunity, so you spot the less-crowded keywords for your title, brand, and bullets.
Branch into related niches
Found a winning niche? Related Niches surfaces dozens of adjacent, proven angles around it — so you turn one validated idea into a whole catalog of Amazon Merch designs instead of guessing what to make next.
Turn a validated niche into a Merch listing
Amazon Merch gives you a brand, a title, two bullets and a description, and it enforces them hard: no claims about fabric or delivery, no asking for reviews, no “glitter” or “glow in the dark” on a flat print. One click on a winning design hands you a listing written inside those limits, for a new design of your own in the same niche. The niche and the keywords come from the winner. The artwork and the slogan never do.
New & selling: first sales, counted
On Amazon a review is a confirmed sale, so a design with 1 to 19 reviews has started selling but has not been on the shelf long. Trendlytic marks each of those cards New & selling and the Niche Verdict adds them up, so a line like 26 new designs with their first sales tells you buyers are still rewarding fresh entries in this niche. A verdict built on old bestsellers alone would hide exactly that.
Built-in trademark check
Check any phrase against the live USPTO register before you design
Type a phrase and Trendlytic looks it up in the live USPTO register and shows who owns it, its status and its filing date. Included in every plan.
And the designs that were never yours to print are marked
When a result leans on a known brand, a character or a famous person, it arrives with a TM or copyright badge on the card. You see it while you are choosing, not after a takedown. A first filter, not legal advice.

Frequently asked questions
What is Amazon Merch research?
It's the step of validating a niche before you create a design for Amazon Merch on Demand: checking what's already selling, whether demand outweighs competition, and whether the phrase is trademarked. Done well, it's the difference between designs that sell and designs that sit.
How is this different from a keyword tool?
A keyword tool gives you search terms. Trendlytic is store-first: it shows the designs actually selling in a niche across four marketplaces, plus demand-vs-competition and a trademark check — so you validate the opportunity, not just the words. For keywords, our free Amazon Merch keyword generator pairs with it.
Does it cover Amazon Merch on Demand specifically?
Yes. Amazon Merch is one of the four marketplaces Trendlytic searches in a single query, alongside Etsy, Redbubble, and TeePublic.
Why does the trademark check matter for Amazon Merch?
A trademarked phrase on a shirt is the most common reason Amazon Merch accounts get suspended. In Trendlytic you click the phrase and we look it up against the live USPTO register, so you see any registrations standing on it before you upload. Treat it as a first filter, not legal advice.
How much does it cost?
There's a 3-day free trial. Paid plans start at $9/month for 100 searches across all four marketplaces, with the trademark check included in every plan.
Is research really necessary if I publish a lot of designs?
Volume without research mostly produces designs nobody searches for. Researching demand and saturation first means more of your limited upload slots land on niches that can actually sell.
Can you sell AI-generated designs on Amazon Merch?
Amazon has not banned AI-assisted design, but every ordinary rule still applies: the design must be yours to sell, it cannot infringe a trademark or a copyright, and the listing has to obey the content policy. That is the risky part, because AI makes it fast to produce something that lands very close to a design already selling. Trendlytic's generator is built to keep you on the right side of it. It reads a winner only to pull the niche and the keywords, then writes a new slogan and an image prompt for original artwork of your own.
What does New & selling mean on an Amazon result?
It marks a design with 1 to 19 reviews. Every Amazon review is a confirmed sale, so those designs have started selling recently rather than coasting on years of history, and the Niche Verdict counts how many of them a niche has.
How does the 3-day free trial work?
Every plan starts with 3 days free. Starting it charges $1 to check the card is real, and that $1 is not refunded. The plan price itself is only billed when the trial ends, and cancelling before then from Manage Plan means it is never charged.
