Amazon Merch on Demand Automation: Drag, Drop, and Let AI Do the Rest

Amazon Merch on Demand automation in Merch Titans comes down to one screen: Easy Mode. You drag in your designs, switch on the marketplaces you sell on, click Write listings with AI, run Check trademarks if you want it, and press Start upload. The app then fills in Amazon's own create page for each listing, in its own browser window. This guide walks through every step as the app works today (checked Nov 6, 2026), including what it doesn't do.

Most sellers who upload by hand repeat the same loop for every design: open the create page, upload the file, pick products, write a title, write two bullets, search the words for trademarks in another tab, submit. Easy Mode keeps the parts that need you, the designs and the final read-through, and hands the form-filling to the app.

What Amazon Merch on Demand Automation Looks Like in Merch Titans

Here is the real sequence, in the order the app shows it:

1. Add designs. Drag PNG or JPEG files into step 1, "Add your designs".
2. Choose where to sell. Switch on Amazon Merch and any of Printful, Redbubble, TeePublic and Printify.
3. Write listings with AI. Pick which fields to fill, and the AI writes them for every design.
4. Check trademarks, if you want to. Run the check, read the results, and click Fix all trademarks if you want the flagged fields rewritten.
5. Start upload. Easy Mode builds the upload list and opens the upload screen, where you tick the listings you want and press Start upload again.

You can edit any field before you upload, and nothing in steps 3 and 4 happens until you click the button. The full reference is in the Easy Mode docs.

Easy Mode, Step by Step

Step 1: Add your designs

The drop zone reads "Drop your designs here", or you click to choose files, and you can add many at once. Above it the app says: "PNG files work best: transparent background, 4500 pixels wide or more."

That line is advice, not a rule. Easy Mode only checks that each file is a real PNG or JPEG, and skips any file that isn't with a message saying so. It doesn't check transparency, pixel size or DPI, so check your own files against Amazon's requirements for each product. For reference, the app's Amazon product table lists the standard t-shirt print area as 4500 x 5400 px.

Easy Mode keeps your designs, their text and your marketplace choices between app restarts, so a half-finished batch is still there tomorrow.

Step 2: Choose where to sell

Step 2, "Where do you want to sell?", has a switch for each marketplace: Amazon Merch, Printful, Redbubble, TeePublic and Printify. Each one you switch on gets a status card that says "Settings look good" or lists what's missing. Click a card to open that marketplace's settings. Printify and Printful also get a Store dropdown here.

For Amazon Merch, the simplest setting is "Use my Amazon publish settings", marked Recommended in the app. It uses the products, prices and colours you saved on Amazon's own Create page with Save publish settings, so there's nothing else to set up. If you'd rather pick products and prices in the app, choose "Choose them here". Both are covered in the Amazon Merch docs.

Step 3: Review your listings

Each design gets a card with the fields your marketplaces need:

The action bar holds the buttons that do the work: Write listings with AI, Check trademarks, Fix all trademarks (it only appears when there's something to fix) and Start upload. When Amazon Merch is on, an "On Amazon:" switch sets this batch to Publish or Save as draft.

AI Listing Writing That's Built In

Click Write listings with AI and a dialog asks which fields to fill: Title, Description, Tags, Primary Tag, Brand, Amazon Bullet #1 and Amazon Bullet #2, limited to the ones your marketplaces use. Only the fields you tick are overwritten, so you can keep a title you wrote yourself and let the AI do the bullets.

What you should know about it:

• No API key. The AI is built into the app. You don't sign up for an AI service or paste a key anywhere.
• It reads the design. The app sends a smaller copy of each design to Google's Gemini model, which writes the text from what it sees. It works through 12 designs at a time and shows a running count while it does.
• Amazon-restricted words. A checkbox, "Filter Amazon-restricted words from tags", strips words such as gift, birthday, glitter, neon and gold from everything the AI writes, not only the tags. You can add your own words to the filter, such as seasonal terms.
• Custom instructions (optional). Under "AI instructions and bulk edit" you can add your own rules, such as a tone or a phrase to avoid. They're added to every AI request.
• It doesn't pull live keyword data. The AI writes from the image and your instructions. Do your keyword research first, for example with our free Amazon keyword research tool, and put the terms that matter in your custom instructions.

The same panel has a bulk edit: pick a field, type some text and click Add Text to append it to that field on every design. It's the quickest way to put one brand name on a whole batch. Description and the bullets get the text on a new line; other fields get it after a space, so type your own comma when you add a tag.

Read every listing before you upload. The AI gives you a fast first draft, but it's your account on the line if a listing breaks Amazon's rules. More detail is in the AI listings docs.

The Trademark Check: Optional, and Only When You Click It

Trademark problems can cost you listings, or your Amazon Merch account, so it's worth being exact about what this check does and doesn't do.

What it is: a button, Check trademarks, on Easy Mode's step 3. It doesn't run on its own, it doesn't run at publish time, and Start upload doesn't need it. If you upload from a spreadsheet instead of Easy Mode, it never runs.

What happens when you click it:

1. A dialog asks which Nice classes to check. Six are ticked by default: 009 (electronics, phone accessories, PopSockets), 018 (bags, backpacks, luggage), 020 (furniture, cushions, pillows), 021 (drinkware, mugs, tumblers), 024 (textiles and fabric goods) and 025 (clothing and apparel).
2. Every field you've filled in, from brand and title to bullets, description and tags, is checked against US trademark records for those classes. It's always the US, whichever marketplaces you've switched on.
3. The same text also runs through a word list kept in the app: profanity, hate speech, 26 big brand names and risky product words.
4. A notification sums up the result, such as "All designs passed trademark check!". Matched marks are listed under the field they appear in, with their risk, and a design that fails gets a Fix Trademark button.

It checks 10 designs at a time. Results aren't kept when you close the app, so run it again after a restart.

The free trademark checker on this website uses the same service and links each result to its USPTO record, if you want to test a phrase before you design. The full detail is in the trademark check docs.

Fix all trademarks

When the check finds matches, a Fix All Trademarks button appears with the number of designs affected. Click it and choose what to remove: single-word trademarks (yellow highlights), multi-word trademarks (red highlights), or both. The app then:

1. Finds the fields that contain a selected mark.
2. Asks the AI to rewrite only those fields, with the marks listed as words it must not use.
3. Checks the rewritten fields again, and repeats up to 5 times per design.

It works through 5 designs at a time and finishes with a count of designs fully fixed, partially fixed (worth a manual look) and failed. Each card also has its own Fix Trademark button for one design at a time.

Two limits to know. It only fixes matches from the trademark records, not words from the app's own list, so profanity or a brand name caught by the word list is yours to edit. And a clean result isn't legal advice. Trademarks are filed all the time, so check close to upload day, and read our guide to avoiding trademark infringement on Amazon Merch.

The math on checking by hand

Take a 50-design Amazon batch with a title, brand, two bullets and a description on each. That's 250 fields, and each one needs a search in every class you sell in. The button sends all of them, 10 designs at a time, and you only read the ones that come back flagged. That's the real saving: your attention goes to the handful of problems instead of the 250 fields that are fine.

The Full Pipeline: From Design File to Uploaded Listing

Step 1: Drop your designs

Open Easy Mode and drag in your PNG or JPEG files. Then click Next: Where to sell.

Step 2: Switch on your marketplaces

Turn on Amazon Merch and anything else you sell on. Fix whatever a status card says is missing, then click Next: Listings.

Step 3: Write listings with AI

Tick the fields to fill, add custom instructions if you have them, and start the analysis. Edit anything you don't like.

Step 4: Check trademarks and fix, if you choose to

Run Check trademarks, read the "Trademark matches" lines under any flagged field, and use Fix All Trademarks or edit by hand. You can skip this step; the app won't stop you.

Step 5: Start upload, then start it again

Easy Mode's Start upload checks every design for missing fields, such as "Design 3: Amazon Merch Brand is required", and checks that each marketplace is set up. Then it builds the upload list and opens the upload screen. The upload itself starts when you press Start upload on that screen, after you've ticked or unticked listings for each marketplace.

On the first upload from a computer, the app checks your licence and asks which subscription to activate it on. Each subscription covers 2 computers (see licence and computers).

Each marketplace you ticked listings for then starts 2 seconds after the one before, and they run at the same time. Amazon Merch runs in a browser window the app opens. Sign in to Amazon there the first time, and the app can keep you signed in. Amazon listings go one after another in a single tab, with a random pause of 5 to 10 seconds between them. If one marketplace hits a problem, the others carry on.

Follow progress on the Upload Status page, which shows a count, a progress bar and an icon per marketplace for each run. Manage Uploads reopens a run so you can see each listing and retry anything that failed (see the Upload Status docs).

How long a batch takes depends mostly on Amazon: how quickly its create page takes each file and how many products each listing has. Your hands-on part is adding the designs and reading the listings.

What's New in Merch Titans 3 (November 2026)

From the app's own changelog:

• Google Keyword Research for broader SEO planning

The Old Playbook Is Dead, but Don't Stop Reading Your Listings

Here's the take some sellers won't want to hear.

The "grind it out manually" approach to Amazon Merch on Demand is no longer a competitive strategy. Sellers still filling in every form by hand are spending their best hours on data entry. That isn't a discipline problem. It's a tooling problem.

The other half of the take is less popular with automation fans: automation makes bad listings faster too. An AI title that names a character, or a bullet that promises a material the product doesn't have, goes out just as quickly as a good one. That's why the AI and the trademark check in Easy Mode are buttons you press and results you read, not steps that run unseen. The sellers who scale keep the judgment calls (design selection, niche research, the final read) and automate the typing.

If you are spending more time uploading than designing, something is broken. And it is not your work ethic.

Who This Is For and Who It Is Not

We are not going to pretend this is for everyone.

Merch Titans Automation is built for sellers who upload in batches. If you upload 5 designs a month as a hobby, you probably do not need it. Manual uploading at that volume is fine.

But if you are:

• Tier 100+ and filling your daily upload limit by hand
• Multi-marketplace and tired of writing separate listings for Amazon Merch, Redbubble, TeePublic, Printify and Printful
• Worried about trademark risk and want a check you can run on a whole batch before you upload
• Spending more time on admin work than on design and strategy

Then it's worth a look. One plan covers everything: $39.99 a month, or $29.99 a month billed annually, with a 14-day money-back guarantee and 2 computers per subscription. See pricing. More than 118,000 sellers have signed up for Merch Titans since 2018.

The future of Amazon Merch on Demand is not about who can upload the longest. It is about who can upload the smartest, and still read what goes out under their name.

Selling beyond Amazon: if you also sell print-on-demand or digital products on Etsy, Shopify, WooCommerce or TikTok Shop, MyDesigns (mydesigns.io) is an all-in-one platform for that. MyDesigns writes titles, tags and descriptions with Vision AI and bulk-publishes to Etsy, Shopify, WooCommerce, TikTok Shop or your own MyDesigns Store. Plans start free; paid plans run from $19.99/mo billed yearly. See MyDesigns bulk publish
