The best AI agent for most ecommerce stores is the one built into your platform, so start with Shopify Sidekick or Amazon Seller Assistant. Add a support agent such as Gorgias, Yuma, or Siena once ticket volume justifies it. Then consider Klaviyo for email or Triple Whale for analytics.
An AI agent plans steps and takes actions, such as editing a discount or refunding an order. Stores have a lot of repeatable tasks, which suits agents well. They also have real money moving through them, so permissions and approvals matter from day one.

How we chose
- We read vendor documentation and pricing pages. We did not run our own tests.
- We looked for products that take actions or complete store tasks, not just chat.
- We valued public prices and clear definitions of what you pay for.
- We covered several jobs, because no single tool runs a whole store.
- Conversion and automation rates on vendor sites are the vendors' own claims.
- The numbering is not a ranking. For underlying AI model positions, see the leaderboard.
1. Shopify Sidekick: start here on Shopify
Best for: Shopify merchants, from solo owners to growing teams.
Price: Shopify describes its AI assistant as built into every store. Its plans start at $29 a month for Basic, and Basic lists a built-in AI assistant.
Shopify's help page on Sidekick says it uses your store's data and presents changes for review before applying them. For tasks with several steps, it plans them and works through them. Longer tasks continue in the background, and it can build Shopify Flow workflows for repeated work.
That review step is the key design choice. You can ask for a discount setup or a report, then check what it proposes. Reading each proposed change takes little time compared with the cost of a wrong discount.
Where it falls short: It only works in Shopify. It is built for store operations, not for answering your customers or running ad accounts on other platforms. Complex edits still deserve a careful read.
Our take: If you are on Shopify, use this first, since you are already paying for the platform. It will show you what you want from any other agent.
2. Amazon Seller Assistant: start here on Amazon
Best for: Independent sellers on Amazon.
Price: Free, according to Amazon's announcement. Amazon says it is available at no additional cost to US store sellers.
Amazon says Seller Assistant uses agentic AI to plan, reason, and act on a seller's behalf, with the seller's permission. It covers inventory, compliance, ad creation, and growth strategy. The original article dates from September 2025 and has since been updated.
The compliance piece may be the most useful for small sellers. Listing and product rules are complicated, and getting one wrong can hurt your account. Treat its answers as a starting point, not as a legal opinion, especially for regulated categories.
Where it falls short: It works inside Amazon's ecosystem, so it will not help your own store or other marketplaces. The vendor is also the marketplace, so recommendations such as ad spending deserve your own check.
Our take: An easy decision at this price. Use it, but check the financial impact of any ad or inventory suggestion before you approve it.
3. Gorgias AI Agent: support in a store-focused help desk
Best for: Shopify brands that want support and sales in one inbox.
Price: Gorgias pricing starts with a $40 monthly plan including 50 tickets and 30 automated interactions. Pro is $550 monthly or $471 annually. Extra AI interactions cost $1.50 each.
Gorgias charges by ticket volume, not by staff seat. It connects with Shopify, BigCommerce, Magento, and WooCommerce, plus tools such as Loop Returns and Recharge. Those links let an agent look up an order and act on it rather than only answer general questions.
Peak-season maths deserves attention. A surge in where-is-my-order questions can push you well past your included interactions. Forecast your busiest month, not your average one.
Where it falls short: You are moving your help desk if you are not already on Gorgias. Unit costs can run higher than some alternatives.
Our take: The straightforward pick for many Shopify brands. Compare it with cheaper per-outcome options at your actual volume.
4. Yuma AI: agents on your current help desk
Best for: Brands with high ticket volume that want automation without replacing a help desk.
Price: Yuma's pricing page shows a Starter example at $14,400 a year for 12,000 resolutions, about $1.20 each. Prices are marked illustrative, paid upfront, on a 12-month commitment. It also describes a free 30-day trial on real ticket data.
Yuma plugs into Gorgias, Zendesk, Kustomer, Gladly, and Re:amaze, along with your Shopify store. It handles order status, returns, refunds, cancellations, subscription changes, and address edits. It bills only for full resolutions, meaning tickets handled with no human involved at any point.
That definition is stricter than some rivals' definitions. A stricter definition tends to protect you from paying for tickets the agent did not really solve. The trade-off is that you commit to a year upfront.
Where it falls short: The annual commitment is heavy for a small brand. It is focused on Shopify-style ecommerce, so check your platform. Refund actions need firm limits.
Our take: Good for brands that can forecast their volume. Use the trial to set your own success target before you sign.
5. Siena AI: support and shopping for growing brands
Best for: Consumer brands wanting one agent across support, shopping, and social.
Price: Contact sales. Siena's pricing page says to tell it what you need and it will send pricing.
Siena positions itself around empathic AI agents for commerce, and its site highlights a $17M Series A raise. It connects to Shopify and covers support, shopping, and social channels. Its site includes customer stories with automation figures, which describe those customers rather than a typical result.
Tone matters more for some categories than others. A skincare or supplements brand may care a lot about how an agent speaks. Be careful with health claims in those categories, because an agent can overstate what a product does.
Where it falls short: No public price, so budgeting needs a sales step. As a younger, venture-funded vendor, ask about data export and contract exit terms.
Our take: A good shortlist candidate if brand voice is central to your store. Test it on your most emotional tickets, not just on order status.
6. Klaviyo Composer and Customer Agent: email plus service
Best for: Stores that already use Klaviyo for email and SMS.
Price: Klaviyo's pricing page offers a free plan with up to 250 active profiles. It includes $5 of mobile messages and $5 of Composer usage a month. Customer Agent is listed under AI Agents with a talk-to-sales path.
Klaviyo's AI page describes Composer as a marketing agent that can analyze data, run audits on a schedule, and build reusable skills. Klaviyo also says your data can be queried by other agents over MCP, an open standard for connecting AI tools. It includes a draft-and-schedule flow with your approval.
Email is a useful place to try an agent, because your customer data is already there. It is also where a mistake reaches your whole list at once. Keep approval on for every send, at least at first.
Where it falls short: Composer pricing beyond the free allowance and Customer Agent pricing were not on the page. Paid plans grow with your list size. Consent and email law still apply to anything it sends.
Our take: A clear add for Klaviyo stores, and not a reason to switch by itself. Set a spending cap before you let it run scheduled work.
7. Triple Whale Moby: analytics that act
Best for: Brands spending enough on ads to need clear attribution.
Price: Triple Whale's pricing page offers a free option and says every paid plan includes daily Moby use. We could not confirm paid dollar figures from the page text, so ask for a quote.
Moby starts as an analyst that explains changes in your performance data. Triple Whale says higher plans shift it from answering questions to running work within your guardrails. Measurement tools like marketing mix modeling and incrementality testing sit on the larger plans.
An agent analyzing your own numbers is a lower-risk first step than one spending your money. Ask it why revenue fell, then check its answer against your own dashboards. Only then consider letting it change a budget.
Where it falls short: Analytics agents are only as accurate as your tracking, so fix attribution and consent issues first. Small stores may not have enough data to make this useful.
Our take: Worth a look for brands with meaningful ad budgets. Keep budget changes behind human approval.
8. Alhena AI: a shopping concierge with a free tier
Best for: Stores that want an on-site shopping agent and a view of AI visibility.
Price: Alhena's pricing has a free plan with 25 conversations a month. Essentials is $199 a month billed annually, or $239 monthly, with 200 conversations and a 14-day trial.
Alhena, formerly called Gleen, combines an AI concierge with monitoring of how your brand appears in AI engines. That combination fits a shift where shoppers increasingly ask assistants for product advice. Our piece on AI product recommendations covers that side.
The free tier lets you test whether shoppers want to chat at all. Many stores never check. Look at whether conversations lead to orders, and whether they just reduce simple questions.
Where it falls short: A price per conversation can look high on the Essentials plan if your chat volume is large. Product guidance has to come from accurate data, so errors in your catalog become errors in chat.
Our take: An inexpensive experiment for stores curious about conversational shopping. Clean your product data before you judge it.
How to choose
Work in this order:
- Use what you already pay for. Sidekick, Seller Assistant, and Klaviyo's allowance cost little to try.
- Automate your top support questions next. Export a month of tickets and count order status, returns, and address changes.
- Compare per-outcome costs at peak volume. Our cost per task guide shows how to run the numbers.
- Then look at analytics and marketing agents. These need more data and more trust.
Limit what an agent can do with money. Set refund caps, block discount stacking, and require approval on bulk changes to prices or inventory. Our human approval table gives you a way to decide which actions need sign-off.
Security matters too, because customer messages can contain instructions designed to trick an agent. A message could tell the agent to ignore its rules and approve a refund. Limits belong in your systems as well as in the prompt. Read our guide to agent security risks before you give refund access.

Frequently asked questions
Do small online stores need an AI agent?
Often only what comes with their platform. If you get a few dozen tickets a month, you can use built-in tools and good help content. A dedicated support agent makes sense when repeat questions are eating your week.
Can an AI agent issue refunds on its own?
Many support agents can, if you connect the store and allow it. Start with low-value refunds under clear rules, and keep logs. Require a person above a set amount, and watch for customers learning how to game it.
How are ecommerce AI agents priced?
Common models are per interaction, per resolution, or a flat plan. Gorgias lists $1.50 per extra interaction, while Yuma's example works out to about $1.20 per full resolution. Always compare how each vendor defines what it charges for.
Will an AI agent hurt my brand voice?
It can if you skip the setup. Give it examples of your tone, your banned phrases, and your escalation rules. Review a sample of conversations each week, especially with upset customers.
Which AI model is the best for ecommerce agents?
We do not name one, because the positions change each week. See the overall leaderboard. In practice, store integrations and your data quality tend to matter more.
