ApiMate vs Shopify Sidekick

Sidekick is Shopify's AI assistant. It answers questions about sales and orders, builds reports and customer segments, writes product descriptions and emails, edits themes, drafts Flow workflows from a description, and can generate a custom app. Sidekick Pulse suggests things to look at without being asked. It is included with your Shopify plan.

In the new look of the Shopify admin, Sidekick moved from a side panel to a chat bar at the bottom of every page, including inside apps. It is the first place a merchant types a request.

Shopify states that Sidekick does not change anything without your approval. Its help pages describe memory of about three months of conversations and reusable Skills that you run by hand. As of 9 October 2026 they do not describe undo for product changes, a limit on how many products one request can change, or a history of the changes Sidekick made.

ApiMate is a Shopify app with a chat that reads and writes your catalog. You write the request as a sentence: "every product in the Winter collection: raise the price by 10 percent and round to .99, skip anything with a compare-at price". ApiMate finds the products, applies the rule and shows a preview with one row per variant: current price, new price and why the row is in scope.

Nothing writes until you approve that exact plan. After approval the job runs in batches and is saved in history with the values it replaced. Supported edits can be reverted with one instruction; irreversible operations are labelled before approval. Questions such as "which products have no SEO description?" are reads: they return a report and need no approval.

Some catalog jobs come up in almost every store, so ApiMate ships them as skills in the + menu of the chat. Pick one, add details if you want (a collection, a margin floor), and you get the same row preview and approval as any other request. The arithmetic in these jobs, margins, check digits and sale floors, is computed in code, not guessed by the model.

Sidekick has reusable skills too, and Shopify documents it filling in the SEO title and meta description on a product's form, one product at a time. ApiMate's distinction is the catalog workflow: rules checked in code, a preview of the affected rows and an Undo for supported edits. These five skills package that workflow for common catalog jobs.

A common catalog job: rewrite the SEO title and meta description for every product in three collections, about 1,200 products, to one pattern.

In Sidekick: you type the request in the bar. Sidekick asks for approval before it changes anything. An independent review from 14 September 2026 reported that Sidekick stopped after two records and offered no metafield support. Shopify Community threads from August 2026 describe Sidekick stopping halfway through a task, and the replies recommend checking each change by hand.

In ApiMate: you send the same sentence in the app. The preview lists all 1,200 rows with the current and new title and description. You approve once. If the new titles read badly, you revert the job from history.

Sidekick is already in your admin, costs nothing extra and covers the whole store, not only the catalog. For most work outside bulk catalog changes, start there.

ApiMate is for the request where a mistake costs an afternoon: many products, a rule with exceptions, and values you may want back.

Both tools ask before they change anything. The difference is what you see before the write and what you can do after it.

Sidekick is included with every Shopify plan. Shopify says usage limits vary by plan and does not publish them, so there is no separate bill and no published ceiling.

ApiMate has a free plan and paid plans by usage. The free plan runs audits and small jobs on any catalog size. The estimate for each job is shown before it runs, and a job cannot spend past the balance.

For questions and content, Sidekick costs nothing extra and is the obvious start. ApiMate is worth paying for when the catalog jobs are large or frequent enough that a row preview and an Undo save more time than they cost.

Shopify publishes no figure for how many products one Sidekick request can change. The independent review and the Community threads above report Sidekick stopping partway through multi-record jobs.

ApiMate has no per-job cap; a large catalog changes the estimate and the run time. The preview for a large job is the scope line first and paginated rows below. Long jobs report per batch and can be stopped partway, with the written rows revertable as a set.

Neither is the tool for a platform migration. That is a file job for Matrixify.

Most stores will keep both. Sidekick stays in the admin for questions, reports, content and themes. ApiMate takes the catalog jobs that need a row preview and a way back.

Inside the app the two sit close together: the ApiMate chat is the panel in the app, and the bar at the bottom of the screen is Sidekick. A request typed into the bar goes to Shopify, not to ApiMate.

Run one real catalog job through each on a small scope. Then check these.

Sidekick does not talk to your customers. Shopify says its usage limits vary by plan and does not publish them.

ApiMate does not write marketing emails, edit themes or build Flow workflows. It accepts supplier price files for cost and margin jobs. For a platform migration or a general catalog import or export, use Matrixify.
