The embed to switch on is Matter Chat.

Install the app, switch on the embed

Install Matter Chat from the Shopify App Store inside your store's admin. That creates your workspace and an assistant already allowed on your storefront's domain, so there is no separate signup and no key to copy. Then open the theme editor, go to App embeds, switch Matter Chat on, and save. If you would rather not add an app, the two-line snippet still works: paste it into theme.liquid just before the closing body tag.

The app (recommended): No theme code to edit. The app embed puts the widget on every page, and switching it off removes it cleanly.
Billed through Shopify: Plans are charged on your Shopify bill, and every plan starts with a 14-day free trial.
The snippet, if you prefer: Online Store, Themes, Edit code, theme.liquid. Duplicate the theme first, preview, then publish.
Async, so it does not block: The script loads asynchronously, so it never blocks the page from rendering.

Installing adds the app but does not show the widget yet: switch the Matter Chat embed on under App embeds and save. The app’s page in your Shopify admin has a button that opens that screen.

It reads your store, not a generic FAQ

Point it at your storefront and it indexes your product pages, policy pages, and any help content you publish. Answers about your shipping windows come from your shipping page, cited — not from an assumption about how stores usually work.

Costs that survive Black Friday

Domain locks tie the widget to your store, per-visitor rate limits stop one person consuming your allowance, and a hard daily reply cap sets the ceiling. A traffic spike raises conversations, not an unbounded bill.

Checking it actually worked

Four things, in order. The third is the one people skip, and it is the one that tells you whether the answers are grounded.

1Hard refresh the page — the launcher appears bottom-right.
2Ask it something your site answers, and check the reply cites a page.
3Ask it something your site does not cover, and check it declines.
4Open Conversations in the dashboard; both should be there.

On a different stack?

The snippet is the same everywhere. Only the place you paste it changes.

See it working

We built a shop so you can interrogate it.

LUMIÈRE is a demonstration storefront of ours — real product pages, a real shipping table, a real returns policy. The assistant on it has read those pages and nothing else. Go and try to catch it out.

Open the demo store

Opens in a new tab. Nothing to sign up for, and nothing is for sale.

The LUMIÈRE storefront with the assistant open. Asked “What is your return window?”, it answers “You have 30 days from delivery to return an item. It must be unused and in its original packaging”, followed by two citation markers and a source chip reading “Returns & exchanges”. — A real exchange on that storefront. Two citations and the page they came from, exactly as they rendered.

Four things worth asking it

“What is your return window?”
Answers from the returns page, and links it
“Who pays for return shipping?”
Splits the answer — faulty vs changed your mind
“Is the stoneware dishwasher safe?”
Pulls the firing temperature off the care guide
“Do you gift wrap?”
Nothing on the site says. Watch it decline rather than guess

What store owners ask

Short answers. If yours is not here, the assistant on this page will try it — and tell you honestly if it cannot.

Do I need to install a Shopify app?

No, but it is the quickest route. Install Matter Chat from the Shopify App Store, switch on its app embed, and it is live with no code and billing on your Shopify invoice. If you would rather not add an app, paste the two-line snippet into theme.liquid instead.

What does the app get access to?

Read access to your themes, and nothing else. It uses that to tell whether the embed is switched on and to open the theme editor for you. It cannot see your orders, customers, or products.

Will it slow down my store?

The app embed and the snippet load the same small script asynchronously, so it does not block page rendering, and neither one touches your product templates.

Can it look up an order status?

No — it answers from your published content rather than from your Shopify data. Order-specific questions escalate to you with the conversation attached.
