EComposer vs Sidekick: who does what in your Shopify store
Sidekick runs your store. EComposer builds the pages that sell. One is the AI assistant inside your Shopify admin, the other is the page builder for your storefront, so the real question is not which one, but who does what.
Your assistant in the Shopify admin
Ask in plain words. It answers questions, drafts store changes for you to review, writes copy and builds reports.
Your page builder for the storefront
Drag and drop the pages your customers see, then test, upsell and measure every one of them. No code.
The short answer
Different jobs, same goal: more sales
-
Sidekick
Use Sidekick when
The job lives in your admin: products, collections, discounts, customer segments, reports, Flow workflows, theme settings and quick questions about how Shopify works.
-
EComposer
Use EComposer when
The job is a page a customer sees: homepage, product, collection, landing and sales pages that need a proven layout, A/B tests, upsells and page-level analytics.

Use both when
You launch something. Sidekick sets up the products and the offer, EComposer builds and tests the page that sells it.

They already work together
Ask Sidekick about your EComposer pages
With EComposer installed, Sidekick can look up the pages you built and how they perform, without leaving the chat.
- Find any EComposer page or template by name, type or status
- See which pages were edited most recently
- Check sessions, visitors, added to cart and conversion rate for the last 7, 30 or 90 days
- Jump straight into that page in the EComposer editor
Lookups are read-only. You still build and publish in EComposer. Page stats need EComposer Page Analytics turned on.

Done for you
Want both, set up by people who know them?
Our team sets up your store with Sidekick, then designs the pages that convert in EComposer, and shows you how to keep improving both.
Is Sidekick a page builder?
No. Sidekick is the AI assistant in your Shopify admin. In the theme editor it can change theme settings, add sections your theme already includes and generate new theme blocks, but it doesn't give you a drag and drop page editor, a template library, A/B tests or page analytics. That is what EComposer is for.
Can I use Sidekick and EComposer together?
Yes, and that is the point. Use Sidekick for products, discounts, reports and automations, and EComposer for the pages your customers see. With EComposer installed, you can even ask Sidekick to find your EComposer pages and check how they perform.
Can Sidekick edit my EComposer pages?
Sidekick can look up your EComposer pages, recent edits and page stats, and link you to the page in the editor. Designing and publishing happens in EComposer.
Do I need to code with either one?
No. You talk to Sidekick in plain words, and you build in EComposer by drag and drop. If Sidekick generates a theme block, its code lives in your theme and you review it before keeping it.
Which pages should I build in EComposer?
The ones that need to sell: homepage, product pages, collection pages, landing and sales pages, and seasonal campaigns. That is where templates, A/B tests, upsells and page analytics pay off.
How much does EComposer cost?
EComposer has a Free plan, and paid plans start at $19 a month billed yearly. See the pricing page for what each plan includes.
