Tandem Get early access

Shopify app · product recommendations

Cross-sell and related products, built from your own catalog

Tandem proposes two blocks for every product page: “Pairs well with” — a helmet for a bike, a case for a phone — and “Similar” for shoppers comparing options. The autopilot drafts them on day one, without sales history. You review every proposal before shoppers see it.

Everything a cross-sell app should do — and a few things they don't

Autopilot proposals

Tandem works out what each product is and what goes with it, from titles, tags, collections and properties — even when product types and categories are empty.

“Pairs well with” as a set

Show accessories as a ready set with a total and one “Add to cart” button, or as a list, grid or carousel.

Similar products that fit

Alternatives that keep what matters: size, gender, wheel size or model. Only what is in stock.

Rules in plain words

What to show for a category, a collection, chosen products or a product property. Your rules always win over the autopilot.

Promo campaigns

Put chosen products first in recommendations for the dates you set, with a label on the card.

Block analytics

Views, clicks and adds to cart from the blocks, by block and by day (Pro).

Questions merchants ask

Does Tandem need my order history?

No. The autopilot builds proposals from your catalog — titles, tags, collections, properties — so Tandem is useful from the first day, in a new store too.

Can I change what the autopilot suggests?

Yes. Every proposal waits for you: accept, edit or skip it. Your own rules for categories, collections, chosen products or properties always come first.

Will it slow down my store?

Finished recommendations are stored in your store and rendered by theme blocks, so the product page does not wait for our server.

Which themes are supported?

Any Online Store 2.0 theme. Blocks are added in the theme editor and take fonts, colors and buttons from your theme by default.

Does Tandem access my customers?

No. Tandem reads products and writes recommendations into your store. It does not read customer records.

Which languages does it speak?

The admin is available in 10 languages, picked from your Shopify admin; block titles follow your storefront language.
