AI customer service for an ecommerce store: replies in your voice, sent with your OK

Updated 2026-11-06 · Leviosa AI

AI customer service for an ecommerce store means an AI that reads what buyers write, finds the facts, and drafts the answer. For a small seller, the safe setup is an agent that drafts in your voice and waits for your OK. It reads reviews, DMs and marketplace questions, looks up the order, writes the reply and puts the angry ones first. You read and send, which takes seconds instead of the half hour of digging per message. Below is what to automate, what to keep, and how to set it up.

What customer service covers in a small store

For a seller, customer service is spread across places that don't talk to each other.

• Marketplace messages and questions: each marketplace has its own inbox in its seller center.
• Reviews: star ratings and comments, where a public reply is read by every future buyer.
• DMs: Instagram and other social inboxes, often the busiest for small brands.
• Email: order questions, returns, wholesale requests.

Most of the time goes not into writing but into looking things up: which order, where it is, what the listing said.

Three ways to use AI for ecommerce customer service

They combine. A site chatbot can field "do you ship to Canada?" at 3am while the agent works through the marketplace inbox each hour.

How an AI agent handles a message

1. Reads it. The full message, the buyer's earlier messages and the star rating if it is a review.
2. Looks it up. Opens the order in the seller center, checks the status and tracking, and the listing if the question is about the product.
3. Sorts it. Angry, low-star or urgent messages go to the top. Simple ones are drafted in a batch.
4. Drafts the reply in your voice. Your greeting, your sign-off, the way you apologize, the things you never promise.
5. Waits for your OK. You read the draft and send it, change a word, or tell the agent what to do differently next time.

Teach it your voice

An AI reply sounds generic when it has nothing to go on. Give it what a new hire would get on day one.

• Ten replies you wrote and liked, good and bad cases both.
• Your rules: return window, who pays shipping on returns, what you do for a damaged item.
• Words you use and words you don't. "Hi there" or "Hello". Emojis or none.
• What it must never do: promise a refund, give a delivery date the carrier hasn't, argue in a public review.

Each correction you make on a draft is one more rule. An agent that remembers what you told it needs fewer corrections each week.

What to keep for yourself

Some messages should reach you, not a draft.

• Refunds and chargebacks, where money moves.
• Anything that mentions a lawyer, a regulator, an injury or a safety issue.
• Health, safety or legal claims about the product.
• A buyer who has written three times without an answer they accept.

Tell the agent to flag these and draft nothing, or draft a holding reply only.

Step by step: set up AI replies for reviews and DMs

1. Start with reviews. They are fewer than messages, public, and easy to check.
2. Give the agent a way in. Sign it in to the seller center and the social inbox once, with the login in a vault rather than in a chat.
3. Give it your voice and your rules as above.
4. Run it by hand once. Ask for drafts for the last ten reviews and compare them with what you would have written.
5. Put it on a schedule. Every hour for DMs, every morning for reviews and marketplace questions.
6. Keep approvals on. Read each draft. After a few weeks you'll mostly press OK, which is the point.

Doing it with Yomates

Yomates is a free desktop app from Leviosa AI with a team of AI agents, each driving a real browser on your own computer while you watch. An agent answers reviews, DMs and questions in your voice, and flags the bad ones first.

• Approval before sending. Before anything is sent or posted, the agent stops and asks for your OK on a confirmation card. Nothing goes live without it.
• Any inbox in a browser. It works in seller centers and social inboxes the way you do, with no API needed. It also connects to Gmail, Slack and more than a thousand other apps.
• A support rep in one sentence. The starting team is a manager, a designer and a content creator. Ask for a support rep and you have one.
• Memory and routines. Agents remember what you told them, and any job can run on a schedule, such as checking DMs every hour.
• From your phone. Message the agents on Telegram while you're out. They do the work on the computer and answer in the same chat.
• Logins. Kept in an encrypted vault on your computer or in 1Password, filled in without the agent reading them.

It runs on the ChatGPT, Claude or Gemini plan you already have, or an API key, on Apple Silicon Macs, Windows PCs and Debian-based Linux. Your computer has to be on for the hourly check to run. It works in English and Korean, and the agents answer in your language. For the wider set of store jobs, see AI agents for ecommerce, or start at the Yomates home page.
