Which Shopify Plan Do You Need to Use Seatext AI on Product Pages?
You don't need a special Shopify plan to use Seatext AI on product pages. Seatext installs through your theme's code, so the true requirement is access to Online Store > Themes > Edit code...
Short answer: you don't need a higher Shopify plan just to run Seatext AI on product pages. Seatext installs through your Shopify theme, not through a Shopify plan feature. The only real requirement is that your Shopify subscription lets you edit theme code — specifically theme.liquid and the product template.
If you see Actions > Edit Code under Online Store > Themes, you have the access Seatext needs. If you don't, that's when a plan or theme change may be necessary.
What the Shopify plan question really gets wrong
The question assumes the plan name is the gate. It isn't. The Seatext integration guide lists a set of admin actions: open Online Store, click Themes, open Edit code, find theme.liquid, and locate the product template. Nothing in that list changes based on which Shopify tier you pay for.
So instead of asking “which plan?”, ask “does my theme let me edit code?” That is the practical filter. A lower-cost plan with code access might be enough. A higher plan with a locked theme won't help until the code editor is available.
There is one related catch: each Seatext account is linked to a single primary URL. If you run multiple stores or use development plus production domains, you need separate accounts. That's a Seatext account question, not a Shopify plan question.
How Seatext connects to a product page
Seatext runs through a small JavaScript snippet placed in your Shopify theme. You paste the snippet into Layout/theme.liquid, then add a data- attribute around the product description output in the product template. Once that is in place, the AI agents you activate can read and adapt that content in real time.
- Create a SEATEXT AI account. The guide says you need one before installing the script.
- Copy the JavaScript code from your SEATEXT AI dashboard.
- In Shopify admin, go to Online Store > Themes.
- Click the three dots icon next to your active theme and choose Edit code.
- Open Layout > theme.liquid and paste the code snippet. Save.
- Find the product template. It is usually product.liquid or product-template.liquid.
- Wrap the product description output in the data- attribute.
- Save, then preview a product page and inspect the HTML source for that attribute.
That's the whole technical setup. It doesn't require a special Shopify plan. It requires access to the files that make up your theme.
Decision criteria: the checks that matter
Run through these checks before you install. If you can answer yes to each one, the Shopify plan you have is not the blocker.
- Can you open the theme editor? Look for Online Store > Themes. No theme editor, no Seatext installation.
- Can you edit code? The Edit code action is the door. If it's missing because of your plan or a developer lock, resolve that first.
- Can you find theme.liquid? The JavaScript snippet lives in Layout > theme.liquid. If your theme doesn't have that file, you need a different theme.
- Can you edit the product template? Product descriptions are rendered by files like product.liquid or product-template.liquid. That's where the data- attribute goes.
- Are you using a real domain? Development URLs such as localhost are restricted, and dynamic development domains may not work reliably.
- Do you need one store or several? Each Seatext account is linked to one primary URL. For multiple stores, create one account per store.
Decision rule: if all checks pass, your Shopify plan is fine. If any check fails, that failure is your real blocker — not the plan name.
Key facts: Seatext and Shopify integration
| Requirement | Where to check | Why it matters |
|---|---|---|
| SEATEXT AI account | Before installation | The script won't install without an account. |
| Online Store > Themes | Shopify admin menu | This is the entry point to your theme. |
| Edit code action | Theme actions menu | This opens the editor where the snippet is pasted. |
| Layout > theme.liquid | Layout folder | This is where the JavaScript snippet lives. |
| Product template | product.liquid or product-template.liquid | This file outputs the product description you need to wrap. |
| Valid domain | Account URL | Development URLs such as localhost are restricted. |
| data- attribute | Product page HTML source | Confirms the tag is live after you save. |
Limitations and edge cases
The biggest limitation is not the Shopify plan. It's theme access. If you can't open the code editor, Seatext can't be installed through that path, and no Shopify plan label changes that fact.
Another limitation is account domains. Each SEATEXT AI account is linked to a single primary URL. If you need the same installation on a development domain, a staging site, and a live store, the guide says to create separate accounts for each domain. Development URLs such as localhost are restricted for security reasons, and dynamic development domains may not work properly.
The AI also remains inert until activated. Installing the script and adding the data- attribute won't change your product copy by itself. It just makes the content visible to the agents you later switch on.
Finally, remember that your Shopify plan and your Seatext plan are two different things. Shopify controls theme access. Seatext controls which agents you can activate. If you want the full ecommerce copy agent suite, confirm that your Seatext subscription includes it.
Terminology used in the setup guide
- Edit code: The Shopify theme editor that lets you modify templates and assets.
- theme.liquid: The main layout file that wraps every page in your theme.
- product.liquid / product-template.liquid: Template files that render product page content.
- data- attribute: A custom HTML attribute that marks where the product description output is placed.
- Inert until activated: The script sits in your theme but doesn't alter content until you turn on an agent.
- Primary URL: The single domain linked to your Seatext account.
Frequently asked questions
Do I need Shopify Plus to run Seatext?
No. The Seatext integration guide doesn't require Shopify Plus. It requires theme code access. If your current plan gives you the Edit code option, that's enough.
What if my theme only has product-template.liquid and not product.liquid?
Use whichever file renders the product description. The guide names both as examples. Look for the output code that shows the description on the storefront.
How do I test that Seatext is installed correctly?
Save your changes, preview a product page, and inspect the HTML source with your browser's developer tools. Verify that the data- attribute is present.
Can I use one Seatext account for my dev and live stores?
No. Each account is linked to a single primary URL. The guide says to create separate accounts for multiple domains.
Will Seatext rewrite my product descriptions immediately after installation?
No. The AI remains inert until activated. Installation only adds the script and the marker. You then activate the agents you want.
What if I can't see Edit code in my Shopify admin?
That means your theme or plan isn't giving you code access. Seatext can't be installed through that path until you have that access. Contact Shopify or switch to a theme that allows code editing.
Final check: verify before you install
Run through the decision criteria once more. If you can access Online Store > Themes, open the theme editor, see Layout/theme.liquid, and edit a product template, you've answered the original question: the Shopify plan you're on is enough. The next step is copying the script from your Seatext account and following the Shopify integration guide step by step.
