In May 2025, Amazon launched “Hear the Highlights” on product pages in the shopping app, where AI generates a brief audio summary lasting tens of seconds, allowing users to grasp key product points without scrolling through reviews line by line.

Now, Amazon announced in an official statement that this feature has added a new entry point called “Join the Chat,” where users can directly ask questions to AI, transforming the voice summary from a recorded clip into a two-way conversational dialogue.

How does voice Q&A work? Not just a voice version of search

The operation path for “Join the Chat” is straightforward: open the product page, click the “Hear the Highlights” button below the product image to listen to an AI-generated overall summary, then click the “Join the Chat” icon to input questions via text or voice.

Amazon states that this system will adjust the direction of the next answer based on the user’s previous question, while also avoiding repeating information already provided. For example, if a consumer asks, “Is this coffee maker suitable for beginners,” the AI will not give a generic product description but will respond by integrating real user reviews and experiences.

After Rufus: The fifth piece of the AI shopping puzzle

“Join the Chat” is not an isolated feature but the result of Amazon’s intensive layout over the past two years.

Rufus, launched in February 2024, forms the foundation of this matrix. As a generative AI shopping assistant, Rufus allows users to inquire about products and compare options through dialogue. By the end of 2025, Rufus has over 250 million users, with official estimates suggesting that the incremental sales driven by it reach $12 billion, with a conversion rate 60% higher than traditional search.

Beyond Rufus, Amazon has gradually introduced:

• Interests: continuously tracking user preferences and automatically surfacing new products that match criteria
• Help me decide: providing personalized recommendations based on browsing and purchase history
• Hear the Highlights: voice summaries on product pages (testing since May 2025)
• Join the Chat: interactive voice Q&A (officially launched this April)

Coupled with ongoing enhancements to Alexa+, Amazon’s AI shopping toolchain now covers “active inquiry, passive discovery, decision support, voice summaries, interactive Q&A, voice ordering.”

Closed ecosystem vs. open protocols

As Amazon strengthens its own AI matrix internally, the external competitive landscape is also rapidly reshaping.

In January 2026, Google announced the Universal Commerce Protocol, collaborating with retailers like Shopify, Walmart, and Target to establish cross-platform AI commerce standards. In September 2025, OpenAI launched the Agentic Commerce Protocol, integrated with Stripe, allowing ChatGPT to complete checkouts directly on behalf of users.

The common logic behind these protocols is to enable AI agents (automated programs that can perform tasks on behalf of users) to move freely across different platforms; meanwhile, Amazon has not joined any cross-platform protocols to date.

This choice is understandable. Amazon’s e-commerce ecosystem itself is a closed loop: logistics, payments, advertising, cloud infrastructure (AWS) are all proprietary. Allowing third-party AI agents to intervene would mean opening up pricing information, inventory data, and user behavior data.

McKinsey predicts that AI agent commerce will reach a global scale of $3 to $5 trillion by 2030. Dominance in this market is not just about technological competition but also about data sovereignty.

Currently, “Hear the Highlights” and “Join the Chat” are only available on the US Amazon Shopping App, and not all product pages have enabled voice summaries. Amazon has not announced a timeline for expanding these features to other markets.
