Full Disclosure Up Front
Updated October 16, 2026
Karim, Trendlytic’s founder, emailed me after reading my Amazon Merch guide and offered free access to the Pro plan so I could test it. Trendlytic also offered an affiliate arrangement. It isn’t set up, so links to Trendlytic on this page are plain links for now. If that changes, I’ll update this note. Same standard as every product I write about on this site: I test it myself first, and that doesn’t change based on who reached out.
Here’s what held up under testing and what didn’t.
Short version: Trendlytic searches four print on demand marketplaces at once, Amazon Merch, Etsy, Redbubble, and TeePublic, shows you which designs are actually selling, scores niches for demand and competition, and runs a live USPTO trademark check on any phrase. The trademark checker is the real reason to use it: it correctly flagged a trademarked term and correctly cleared a safe one when I tested both. A newer Brand & Character Guard flags Disney, Star Wars, and similar designs by name. When I first tested it, its niche scores ignored those flags; I reported that, Trendlytic fixed it the same day, and a re-test confirmed protected niches now score a 1. Demand is read entirely through t-shirt sales. Plans now start at $19.99 a month with a 3-day trial, and it’s a young company with a short track record, so weigh that too.
What Trendlytic Actually Does
At its core, Trendlytic searches Amazon Merch, Etsy, Redbubble, and TeePublic at once and tells you what’s actually selling for a niche or keyword, not just what’s been uploaded. Search a niche, “Deep Carrot” was one I tested, and you get real listings with real prices, real review counts, and a plain-language verdict at the top. Mine came back rated as a niche worth entering with a specific angle, based on new designs already getting first sales against the existing competition.
Everything runs on a shared credit system. When I tested it, searching all four marketplaces at once cost 4 credits, and searching one cost 1.
Pricing as of October 2026:
| Plan | Price | Searches a month | Trademark checks a month |
|---|---|---|---|
| Starter | $19.99/month | 100 | 50 |
| Pro | $49.99/month | 500 | 300 |
| Business | $99.99/month | 2,000 | Unlimited |
Every plan comes with a 3-day free trial, with a $1 charge to verify your card, and you can cancel anytime. Prices have gone up since I first tested it, when Pro was $19 a month, so check the current page before you sign up. For a solo seller testing a handful of niches a week before committing design time, Starter is usually enough. Pro makes sense once you’re researching and listing designs every day.
The Trademark Checker Is the Reason to Care About This One
I ran “SpaceX” through it on purpose, because it’s a genuinely bad idea to print, and the tool needed to catch it to earn any trust from me. It did, correctly, showing the mark registered in Class 25, the exact class for clothing, with the actual owner (Space Exploration Technologies Corp.), the filing date, and the expiration pulled straight from the USPTO database. Then I ran a niche phrase with no trademark conflict, and it came back clean instead of throwing a false alarm to look thorough. That’s the distinction that matters. A checker that flags everything isn’t useful, and one that missed SpaceX would be dangerous to rely on.
Every search result also carries a small badge showing whether the phrase leans on a name someone already owns, and clicking it runs the same live check.
For a Merch seller, this matters more than ever. A trademark strike can get your account suspended, and it can also hold back the design tier upgrades that let you list more designs. And since Merch’s June 2026 royalty change cut passive sellers’ pay in half, every design slot has to earn its keep. That makes the trademark checker the one feature worth the subscription on its own.
A tool is still only a first check. Print on demand trademark rules covers how to search the USPTO database yourself, which phrases get sellers sued, and what to do if a takedown notice shows up.
The Brand & Character Guard: Tested, Reported, Fixed
Since my first round of testing, Trendlytic has added what it calls a Brand & Character Guard. It isn’t a separate page. It’s a small red badge on design cards: a © for copyrighted characters and famous people, and a TM for trademarks. Click the badge and it shows exactly which words set it off, highlighted in the listing’s title and tags, explains in plain language why marketplaces take those designs down, and offers a one-click check on the USPTO site.
My first test turned up two real problems. I searched “Mikey Mouse” (misspelled on purpose) and “grogu.” The badges worked: every Disney and Star Wars design in the results got flagged, and my original niche, “Deep Carrot,” came back with no badges and no false alarms. But:
- The niche verdict ignored the badges. Both searches came back rated “Perfect Niche,” 5 out of 5, while nearly every design underneath carried a red “not yours to print” badge. Those niches look wide open precisely because careful sellers stay out of them, so a beginner trusting the big green score was being pointed straight at a takedown.
- Only one protected word got highlighted. In a Star Wars listing, “Star Wars” was highlighted but “grogu,” right there in the tags, wasn’t.
I emailed both findings to Karim. He replied the same day: “grogu” had been on the list all along, but the panel only highlighted the first protected word it found, and the verdict now takes the badges into account. Both fixes went live the same day.
Then I re-tested, October 12:
- “Mikey Mouse” now comes back “Protected Niche,” scored 1, with the count right in the verdict: “40 of 40 designs here use a protected brand or character,” plus advice to study the buyer and style and make something original without the names.
- “grogu” also comes back “Protected Niche,” 1: “‘grogu’ belongs to someone else, and 79 of 79 designs here use a protected brand or character.”
- The panel now catches every protected word. One Star Wars shirt highlighted “Star Wars,” “Baby Yoda,” “grogu,” and “Disney” in the same listing, and listed the extra matches under the headline.
- “Deep Carrot” still scores “Good Opportunity,” 4, and “space cat” came back “Hot Niche,” 4. No false alarms on original niches.
According to Karim, a niche where between a fifth and half of the designs carry badges keeps its verdict but gets a warning line with the count. None of my searches landed in that middle range, so I haven’t seen that warning myself yet.
What hasn’t changed is what it matches. The tool says so itself: it’s a “local pre-check from a curated list, not legal advice.” It reads words, not artwork, and the list covers the big names better than the small ones. In my re-test, “Pluto” and the misspelled “Mikey” in a Disney listing weren’t highlighted, and neither was “Mando” in a Star Wars one. Those listings were flagged anyway because they also said “Disney” or “Star Wars,” but a listing that only uses a lesser-known character name, or a design where the character is only in the picture, can still get through with no badge. Treat a red badge as a definite stop, and no badge as “not flagged,” not as “safe.”
For a review, the fix matters almost as much as the feature. I reported a real flaw, the founder explained exactly what caused it, fixed it the same day, and the fix held up when I checked it myself. That’s a better sign about a young company than any feature list.
The Niche and Design Research
Trending Now shows what’s climbing across all four marketplaces, refreshed hourly. Best Design Instant sorts the strongest current winners into three groups: Gold (proven sellers in niches that are hot right now), Rising (a top seller that was also uploaded recently, which is where there’s still room to get in), and Solid (reliable sellers that never really go out of style). That distinction matters more than it sounds. Gold tells you what’s already crowded. Rising tells you where there’s still space.
The same Rising and Rising fast badges show up on regular search results too. When you see one, the design is both recent and already selling somewhere real, not just a fresh, unproven upload. If you’re deciding what’s worth your design time this week, that badge is a better signal than where something ranks in a search.
Keyword Research pulls the actual tags and phrases best-selling designs use for a niche, then scores each for demand, competition, and trend direction, with an opportunity rating (Great, Good, and so on) so you’re not staring at raw numbers. These scores are relative to that specific search, not fixed industry benchmarks, and the tool says so directly instead of implying more precision than it has. Related Niches branches out from your keyword to nearby ideas you wouldn’t have thought to search, which is genuinely useful for breaking out of the obvious niches.
The POD Calendar keeps a running list of upcoming seasonal events and how many days ahead you should start designing for each, and links straight into the research tools for that event.
The AI Studio: One Standout, a Few Decent Extras
AI Studio bundles Trendlytic’s AI tools, drawing from the same credits as everything else. The Niche Finder takes a broad interest and returns twelve specific niche ideas, each with a one-line reason it works and a sample design concept. Genuinely useful if you’re starting from nothing.
The Listing Generator is the best feature in the whole product, and the one I’d lead with if you’re on the fence. Open any winning design and it doesn’t just hand you that design’s listing to copy. It generates a new slogan, a new design prompt, and a full title, description, and tag set built around that new idea. That’s the right way to learn from a winner and build your own version without drifting into copying someone else’s work.
The Slogan, Quote, and Description generators are fine starting points in the pun-heavy tone POD listings use, but they read as AI-written if you look closely. Treat them as a first draft to edit, not something to post as is.
What It Doesn’t Do
Three things to consider before you sign up.
The Brand & Character Guard matches names, not pictures. As covered above, big brands and well-known characters get caught, but lesser-known character names and designs that only show the character can slip through. It’s a first filter, not a clearance.
It reads demand entirely through t-shirt sales. On Redbubble and TeePublic, the same design automatically goes onto mugs, phone cases, and other products, and Merch sellers add hoodies and other items themselves, so a niche that wins on tees is treated as the same niche everywhere. It doesn’t rank mugs against phone cases as separate categories. I confirmed this directly with Karim rather than assuming.
It’s a young company. Trendlytic launched in 2026 and has little independent track record so far. That said, everything I tested worked as described, Karim answered every specific question I put to him directly and accurately, and when I reported two problems, both were fixed within a day.
Who This Is Actually For
If you’re running an Amazon Merch, Etsy, Redbubble, or TeePublic shop and doing niche research by scrolling bestseller lists by hand, this replaces a genuinely tedious part of the job, and the trademark checker alone is worth having before you upload anything with text on it.
If you’re not doing print on demand yet, start with how to make money with print on demand and come back once you’re actually choosing niches to design for. If you want to turn it into a real business, the print on demand business blueprint lays out the full plan, step by step. And if you sell on Etsy, run your prices through the Etsy POD profit calculator first. A niche is only worth winning if the margin is there after fees, and Etsy vs Shopify for print on demand shows what each one leaves you per shirt.

Frequently Asked Questions
In my testing, yes. I ran SpaceX, a phrase I knew was trademarked, and it correctly flagged it with the exact class, owner, and filing dates pulled from the USPTO database. I also ran a clean phrase and it correctly cleared it instead of over-flagging. That’s the combination that matters: catching real risk without crying wolf on everything.
Yes, by name. Its Brand & Character Guard puts a red badge on designs whose titles or tags use words from a curated list, like Disney, Star Wars, or Baby Yoda, and highlights every word that triggered it. Since October 2026, a niche where most designs are flagged scores “Protected Niche,” 1. It matches words, not artwork, so a lesser-known character name or a design with no names in the listing can still slip through.
As of October 2026: Starter is $19.99 a month (100 searches, 50 trademark checks), Pro is $49.99 a month (500 searches, 300 trademark checks), and Business is $99.99 a month (2,000 searches, unlimited trademark checks). Every plan has a 3-day free trial with a $1 card verification charge. Searching all four marketplaces at once uses more credits than searching one.
It searches four marketplaces, but reads demand through t-shirt sales and treats that as the signal for whatever else a design gets printed on, like mugs, phone cases, or hoodies. It doesn’t rank those products as separate categories. I confirmed this directly with Trendlytic’s founder rather than guessing from the interface.
Based on hands-on testing, yes. The core features work as advertised. It’s a new company that launched in 2026, with little independent review history yet, but everything I personally tested held up, and when I reported two problems with its character guard, the founder explained the cause and both were fixed within a day.
The Listing Generator, inside AI Studio. It turns a proven winning design into a new slogan, a new design prompt, and a full original listing, rather than handing you the winner’s existing text to copy. That helps you build something of your own from real demand data instead of copying someone else’s work.
For a solo seller researching a few niches a week, Starter is usually enough. Pro makes sense once you’re researching and listing designs daily. Use the 3-day trial to run your own trademark test and a few niche searches before you commit to a month.

That trademark checker is useful not only for apparel design, if someone creates any content, it is pretty much mandatory to check copyrights and trademarks. Online platforms are getting increasingly aggressive in enforcing it and loosing account that already generate substantial returns really really hurts. Oh, and it usually comes without warning. Read TOS and check trademarks and IP boys and girls.
Kyle, that’s a really good point and honestly one I should’ve made more explicit in the piece. The trademark risk isn’t just an apparel thing, it’s a “you’re building on someone else’s platform” thing. Same story on KDP, YouTube, print-on-demand, digital products, anywhere you don’t own the rails you’re selling on. Enforcement can be inconsistent and it doesn’t care how long you’ve had the account or how much it’s making. Appreciate you flagging it, might turn this into its own piece down the line.
