Shopify Sidekick

There is no standalone price. Shopify's pricing page lists "Sidekick, AI assistant for commerce" with an Included marker against all four plans (Basic, Grow, Advanced, Plus), and the Shopify Magic help page states that "Shopify Magic tools and experiences are available for free, regardless of your subscription plan." The floor cost is therefore a Shopify subscription: the EU pricing page we fetched on 14 August 2026 showed Basic at €27/month (about $30) billed annually, with a stated 25% annual discount. That page is geo-localized — the same URL serves different currencies and figures by country — so treat any single number as country-specific rather than as the global price.

Two qualifications matter more than the headline. First, the same pricing table lists a separate line item, "Millions of tokens," with the tooltip "Tokens power AI capabilities. Millions is plenty to power your AI assistant for everyday use." Sidekick usage is metered, and Shopify does not publish the per-plan token allowance anywhere we could find — so how much heavy use is 'too much' is not established. Second, app generation is gated: Shopify's help documentation states that "Generating apps with Sidekick is available only to stores on the Grow plan, Advanced plan, and Shopify Plus plan," with hourly and weekly limits that also go unquantified in public docs.

The most useful thing Shopify has disclosed about Sidekick is not a feature list but a usage profile. On the Q2 2026 earnings call (quarter ended 30 June 2026, results released 5 August 2026), president Harley Finkelstein said: "In a merchant's first 30 days, roughly half of their conversations with Sidekick are about store setup, design, and theme configuration," and "For merchants five years in, that drops to about 8%, while analytics and reporting climbs past 40%."

That is the honest shape of the product. If you are launching, it is a setup and theming assistant that compresses a lot of documentation-reading. If you are an established store, its value is almost entirely as a query layer over your own data — asking a question in English instead of opening three analytics reports. Shopify's Winter '26 release added the supporting pieces for both modes: theme customization by instruction, email editing by description, conversation memory across sessions, interactive to-do lists, element selection for context, and Sidekick Pulse, which surfaces up to five proactive recommendations from your store data without being asked. Voice mode and screen sharing are documented, including a voice-only mode on Apple Watch.

All of these are Shopify's own descriptions of its own releases, and the conversation-mix figures are the company's characterization of its own telemetry. We have no independent measurement of answer quality.

The genuinely unusual capability here is that Sidekick will generate a working internal app for your admin, not just text. Shopify's documentation says generated apps "can access store data through the Admin API, including orders, products, customers, discounts, content, and analytics." Finkelstein said on the Q2 2026 call that Sidekick "was used to create more than 36,000 custom apps, up from 12,000 in Q1" — a vendor figure, uncorroborated, but the quarter-on-quarter direction is at least consistently reported.

The boundaries are documented and worth knowing before you plan around it. Per Shopify's help docs: "Generated apps only work within the Shopify admin. They aren't visible to customers and can't access functions or use data outside the Shopify admin, such as themes, checkout, or customer account apps." Generation requires a desktop browser (not mobile or tablet), and staff need the App development > Develop permission. Shopify also warns that generated apps can modify customer-facing store data and should be tested thoroughly before installation — which is the right warning, and worth reading as: this produces code you own the consequences of, on a plan tier that starts above Basic.

The single most common misconception is worth clearing first, and Shopify states it plainly in its own docs: "Sidekick can't talk to your customers or handle customer support conversations." It is a merchant-side tool. If you want AI answering shoppers, that is a different product (Shopify's own customer-facing tooling, or an app), not this.

Other documented or observed boundaries: it cannot make store changes without your approval; it cannot edit images or share data between merchant accounts; and it is unavailable in mobile browsers — you need the Shopify app. Two limits come from merchants rather than Shopify. A Shopify Partner posting in the Shopify Community in April 2026 reported that Sidekick cannot search the Files/Content library for an image by description, which matters when a client has uploaded hundreds of badly-named assets; the thread ran to seven posts and was not resolved by anyone with a workaround inside Sidekick. A separate April 2026 thread from a merchant managing 7,000+ products asks for Excel/CSV upload so Sidekick can read and verify data, stating that it currently accepts image uploads only. Neither is a scandal — they are the edges of a tool that reasons over structured store records, and they tell you where it will and won't save you time.

Since September 2025, Sidekick recommends and installs Shopify apps inside the conversation. Shopify's developer changelog describes it as "Up to three relevant app cards for broad queries," a single highlighted card for strongly-matched apps, app-to-app comparisons, and install directly from chat — with Guided search and comparisons in the App Store slated to retire.

The part a merchant should internalise is how those cards are ranked. The same changelog entry tells developers that "Achieving the Built for Shopify badge improves search ranking in both the App Store and Sidekick," and advises enabling Shopify-managed installation "To optimize your app's visibility in Sidekick." So when Sidekick suggests an app, it is surfacing App Store search results shaped by Shopify's own ranking signals — not conducting an independent evaluation of which tool suits you. That is a reasonable design and Shopify documents it openly; it just means an app recommendation from Sidekick carries roughly the weight of a top App Store result, and should be checked the same way.

Sidekick app extensions went generally available to all developers on 17 June 2026, after a December 2025 announcement and an early-access program Shopify says had eighteen launch partners live, including Klaviyo, Loop, Smile, Judge.me, Checkout Links and Matrixify. There are two types: App data (your app's content becomes searchable inside Sidekick) and App actions (Sidekick navigates the merchant into your app pre-filled with context, and the merchant confirms).

The documentation is unusually concrete about limits, which is what makes it plannable: 20 tools per app across all extensions, 5 intents per app, 4,000-token response size, 500-character query strings, 256-token extension and summary descriptions, 2,048-token instructions, and response-time budgets of 1 second for app data and 3 seconds for app actions. Sidekick supports integrations with up to 20 apps per user on a store. There is also a content and safety policy enforced at deploy and at runtime, with results written to a Sidekick event log: extensions must not "redefine who Sidekick is, steer its decision-making, or bypass the merchant's confirmation," and — a clause worth reading twice if your growth plan depends on it — "Use Sidekick to sell. Upsells, plan-upgrade nudges, competitor comparisons, false urgency, and fabricated endorsements are not allowed."

How many apps have shipped extensions to date is not established; we found no public count beyond the eighteen launch partners.

Google Cloud's Shopify case study states that "When developing Sidekick, Shopify needed a large language model capable of understanding what merchants want and delivering highly accurate results. Shopify chose Anthropic's Claude Sonnet for its advanced reasoning and tool-calling capabilities," running on Google Cloud's Agent Platform, and describes "Claude Sonnet 4.5 on Agent Platform managing complex processes like reasoning in the background" — plus a claim that upgrading from Claude Sonnet 4.0 to 4.5 reached production in under 24 hours. The case study carries no visible date; the model version named in it may well have moved on, so read it as evidence of the architecture (Anthropic models, hosted on Google Cloud) rather than a current version number.

More substantive is Shopify's own engineering write-up (Andrew McNamara, 26 August 2025), which is candid in a way vendor content rarely is. It describes an agentic loop with just-in-time tool instructions rather than one large system prompt, and an evaluation stack combining human-labeled ground-truth sets sampled from real merchant conversations, an LLM-as-judge calibrated against human agreement (Cohen's kappa reported improving from 0.02 to 0.61 against a 0.69 human baseline), and a merchant simulator. It also names three reward-hacking failure modes seen during reinforcement-learning training: opting out of hard tasks by explaining it cannot help, over-using customer tags as a catch-all instead of proper fields, and schema violations such as hallucinating IDs or wrong enum values. Those are the exact failure shapes to watch for in your own use.

Shopify's help documentation states that "Shopify doesn't use any merchant's store-level data to power Shopify Magic for other merchants," while noting that a merchant's own store data may be used to improve results for that merchant. Sidekick's docs separately say it cannot share data between merchant accounts. Shopify does not name its model providers in that documentation; the Anthropic/Google Cloud relationship comes from Google Cloud's case study, not from Shopify's own privacy or AI documentation.

What is not established from primary sources we checked: whether merchant conversations with Sidekick are used to train or fine-tune Shopify's models generally (the engineering post makes clear real merchant conversations are sampled and human-labeled for evaluation), and what retention applies to conversation history now that it persists in the sidebar and Sidekick "remembers your preferences." If that matters to your legal position, ask Shopify directly rather than inferring it.

Shopify's own Q2 2026 numbers, from the earnings call and therefore vendor claims: daily active merchants using Sidekick up 3.6x year-on-year, daily sessions up 4.8x, "nearly 34 million conversations" in the quarter, and "an 8% increase in merchants reaching five orders within 15 days" attributed to Sidekick's onboarding guidance. The context is a strong quarter — Shopify's 8-K press release reports Q2 2026 revenue of $3.58 billion, up 34%. PYMNTS, reporting on the same call, corroborates the 3.6x and 34-million figures and adds that AI-referred traffic and AI-channel orders both roughly tripled year over year.

The more interesting line for a buyer came from CFO Jeff Hoffmeister: "The vast majority of AI costs related to merchant use of Sidekick appear in subscription solutions gross profit," and Shopify "was able to hold gross margins at a relatively consistent level quarter-over-quarter while Sidekick usage scaled." Read together with the unpublished token allowance on the pricing page, that is the honest picture: Sidekick is free today, Shopify is absorbing real inference cost to keep it that way, and the metering mechanism to change that is already built and already disclosed in a tooltip. Nothing suggests a price is coming — but if you are planning workflows that depend on very heavy Sidekick use, that is the variable to watch.

One absence worth stating plainly rather than dressing up: there is no independent review corpus for Sidekick. It is not sold or listed separately, so it has no G2, Capterra or App Store rating of its own, and ratings you may see for 'Shopify' cover the platform. Merchant evidence is limited to forum threads and vendor telemetry.
