What you get
The slogan is the whole shirt. It's also the part a blank page and a generic AI both get wrong: type a topic into most tools and you get flat, obvious lines nobody would wear, with no idea whether the phrase is already trademarked — and a trademarked slogan is the number-one way print-on-demand accounts get suspended. Trendlytic works the other way around. It starts from a niche that's genuinely selling across TeePublic, Amazon Merch, Redbubble and Etsy, writes original, wearable slogans in the tone you pick, leaves every slogan ready for a USPTO lookup on the keywords behind it, and hands you the whole listing to go with them — title, description and per-marketplace tags. Original lines, grounded in real demand, checked before you print.
Original, wearable slogans — not corporate filler
Short lines a person would actually put on a shirt, 2 to 7 words, each a genuinely different angle. No 10 rewordings of the same obvious phrase, and nothing that reads like a stock tagline.
Pick the tone, steer the whole set
Funny, bold, minimal, inspirational, retro, cute or sarcastic — choose a lane and every slogan comes back in it, matched to the audience you're designing for.
Grounded in what's actually selling
The slogans are built around a niche Trendlytic has verified against real store data across four marketplaces, so you're writing for proven demand instead of a phrase that merely gets searched.
A live USPTO trademark check on the keywords
A trademarked phrase is the top cause of suspended POD accounts. Send a niche keyword to the live USPTO database and back comes what is registered on it, so you catch a registered phrase before you print it, not after your account is gone.
The full listing, not just a slogan
One niche gives you the slogan plus a ready-to-paste design prompt, a keyword-rich title, a buyer-facing description, and separate tag sets for TeePublic + Redbubble and Etsy + Amazon. The slogan is the start, not the whole job.

Original slogans, written for a real niche
Enter a niche and pick a tone, and the AI writes a set of short, original slogans built for it — plus the design prompt, title, description and keywords to publish with them. You're not staring at a blank shirt, and you're not pasting a generic line every competitor already used.
Slogans for niches buyers are already reaching for
A slogan lands best where buyers are already spending. Best Niches Today turns the Rising designs of the last three days into a list of niches, each in the words of a real title, with the number of Rising designs behind it. Coffee helps skeleton had 8 the day we took this. The joke has found its buyers; your part is a line of your own for the same people.
Keywords the top sellers actually rank for
The slogans come with the tags that make them findable — the real single-word tags and long-tail phrases proven designs use, each scored for demand and competition, with a 12-month trend curve so you build around phrases still climbing, formatted to each marketplace's own rules.
It writes for niches that are proven to sell
A great slogan on a design in a dead niche still won't sell. Every search reads the designs actually selling across four marketplaces and returns a plain verdict on demand and saturation, so the slogans you generate are aimed at a niche that has buyers — not a phrase that merely gets typed into search.
What the register says about your slogan
A catchy slogan can be a registered trademark even when you came up with it independently, and printing it is how accounts get closed. Run the slogan through the live USPTO register and you find out while it is still a draft rather than after the design exists. The lookup is in every plan.
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.
How it works
- 1
Find a niche that sells
Search any niche and Trendlytic shows what's genuinely selling across TeePublic, Amazon Merch, Redbubble and Etsy, with a saturation verdict, and the USPTO register a search away on the wording you like.
- 2
Generate the slogans
Enter the niche, pick a tone, and the AI writes a set of original, wearable slogans — plus the design prompt, title, description and per-marketplace tags to go with them.
- 3
Check it, then print it
Run the USPTO check on the slogan and a registered phrase turns up before you commit; pick the slogan you like, make the art from the prompt, and publish into a niche you already know has buyers.
Also in every plan
A mockup generator for the design you make next
When your own design for the niche is ready, drop the file in and see it on 500+ t-shirt photos in one go. Pick the shots that fit your shop, on a person or on its own, and save them at up to 2000 px with no watermark. A mockup takes 1 credit from your plan the first time and nothing after that.

Frequently asked questions
What does the AI slogan generator actually produce?
For a niche you choose, it writes a set of short, original slogans in the tone you pick — and, in the app, the full listing to go with them: a ready-to-paste design prompt, a keyword-rich title, a buyer-facing description, and separate tag sets for TeePublic and Redbubble versus Etsy and Amazon. The slogan is the hook; the listing is the rest of the job done.
Are the slogans original, or recycled?
They're written fresh each time for your niche and tone, not pulled from a list of existing shirts. Because slogans are short, the responsible step is still a quick trademark check before you print — which is exactly why the live USPTO check is built into every plan.
Is it free?
There's a free, no-login slogan tool for instant ideas. The AI version — original slogans built on a real winning niche, trademark-aware, with the full listing — is inside the app, on a 3-day free trial, then from $19.99/month for the whole toolkit.
Will an AI-written slogan get my account banned?
Not for being AI-written. Accounts get closed for trademark and IP infringement — printing a phrase, name or character that's registered. That's the whole point of the built-in live USPTO lookup: you run it on the slogan and see the registered marks before you commit it to a design, so you can pick a different slogan instead of losing the account. It is a first check, not legal advice.
How is it different from a generic AI slogan generator?
A generic tool writes a line from a blank prompt with no idea whether the niche sells or the phrase is trademarked. This starts from a niche verified against real store data across four marketplaces, writes for that proven demand, puts the keywords in front of the USPTO register, and hands you the full listing — so the slogan is one people want and one you have looked up first.
What do I get for $19.99 a month?
The whole tool, not just the slogans: 100 searches across all four marketplaces, store-first data on what's genuinely selling, the saturation verdict, keyword research, the live USPTO trademark lookup on the keywords you pick, and the slogan and listing generators. There's a 3-day free trial first.
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.
