The chat widget
The assistant appears on your storefront as a chat widget. It's delivered through a Shopify theme app-embed, so you stay in full control of whether it shows — right from your theme editor.
Enable the widget in your theme
- Open the theme editorIn the Sellena app, open the Chat widget card and click Enable in theme editor. (Or in Shopify admin go to Online Store → Themes → Customize.)
- Turn on the Sellena app embedIn the theme editor, open App embeds in the left sidebar and toggle Sellena on.
- SaveClick Save. The widget appears on your live storefront within a moment.
Why a theme app-embed?
App embeds are the Shopify-recommended way to add a widget. They don't modify your theme code, they load without slowing your store, and you can switch them off any time without uninstalling the app.
Customize the widget
All appearance and behavior settings live in the theme editor alongside the toggle: open App embeds → Sellena, adjust, then Save. Because it's a theme embed, every change previews live in the editor before you publish.
- Launcher position — which corner of the page the chat button sits in (bottom-right or bottom-left).
- Widget theme — six ready-made color themes, or Custom: pick your brand color and the widget derives its entire palette from it — buttons, header, chat bubbles and focus states — with text contrast checked automatically so even very light or very dark brand colors stay readable.
- Launcher label — the tooltip and accessible name of the chat button.
- Proactive invitations — when enabled, the assistant may invite a browsing shopper to chat (for example after they compare several similar products). One gentle invitation per visit, never more.
Brand color on autopilot
With the Custom theme you set exactly one color. Sellena builds the rest — including a readable text color on your brand surfaces — so there's nothing else to tune.
What shoppers can do
Beyond chat, the widget is a full shopping surface. On desktop it opens as a compact panel the shopper can keep beside the page, or expand into a wide view with a product canvas:
- Product cards with photos, sizes, details and prices — tap any card for a detailed quick view.
- Outfit recommendations — when the assistant styles complete looks, the shopper can compare them side by side (each look gets its own name and total), open one in detail, and buy or virtually try on the whole outfit in a click.
- Photo understanding — shoppers can attach a photo and the assistant finds similar items from your catalog.
What keeps the widget live
The widget shows on your storefront when all of these are true:
- The Sellena app embed is enabled in your active theme.
- Your plan is active (billing approved, if billing is on).
- You're within your plan's conversation allowance for the period.
One switch in Shopify
Sellena keeps a Shopify entitlement flag in sync with your billing, so Shopify itself shows or hides the embed toggle based on whether your plan is active. If the toggle looks unavailable, it usually means billing needs approving first — see Billing & plans.
