The news: Amazon on Wednesday announced an update to its AI-powered Seller Assistant that it is framing as a fundamental rethink of the tool, shifting it from an assistant that responds to sellers’ requests to one that continuously monitors their businesses and can take action on their behalf.

New Seller Assistant workflows let merchants automate tasks such as monitoring inventory, adjusting prices, reviewing account health, and identifying competitive opportunities. Sellers describe what they want in plain language, set guardrails, and decide whether the AI should recommend an action or carry it out with their approval.

Amazon is also taking Seller Assistant beyond Seller Central. A new Amazon Selling Partner plugin, launching first with Amazon Quick and in beta with Anthropic’s Claude, connects sellers’ Amazon listings, inventory, sales, and performance data with external AI agents. Those agents can analyze the information and take actions within sellers’ Amazon businesses.

Why it matters: Amazon’s pitch is that Seller Assistant can move from answering questions to taking work off sellers’ plates. A merchant might tell it, “Alert me if any of my top 10 products drops below a 4-star rating and draft a response plan,” or “Monitor my top category for competitive openings. If you see one, adjust my pricing and refresh the listings.”

Making sellers more productive directly benefits Amazon. Third-party merchants account for 68.3% of Amazon’s worldwide sales, so reducing the time and expertise required to operate on its marketplace could help those businesses—and Amazon—sell more. Seller Assistant already has “hundreds of thousands” of active users, who accept its recommendations more than 90% of the time, Amazon says. Its capabilities are available to more than 90% of selling partners worldwide.

Persistent memory could make the tool even more useful. Seller Assistant can remember a merchant’s pricing patterns, inventory cycles, and growth goals, allowing it to tailor its actions over time rather than treating every interaction as a blank slate.

Implications for sellers: As Seller Assistant handles more operational work, Amazon could become more valuable for merchants, particularly smaller sellers without large teams. However, that greater autonomy also raises the stakes for Amazon to ensure its tools get it right. After all, a bad recommendation is one thing, but an AI agent’s misfires—such as an incorrect pricing or inventory change—are considerably more consequential.

Amazon’s decision to bring Seller Assistant into third-party AI tools is equally notable. The company says 90% of its selling partners already use outside AI tools to run their businesses. Rather than fight that behavior, Amazon is meeting sellers where they already work, positioning its marketplace data and capabilities as infrastructure that can plug into whichever AI agent they prefer. That could make Amazon more deeply embedded in sellers’ operations even when they aren’t working directly inside Amazon.
