Yahoo Rebuilds Search Around Scout AI in Biggest Update in Years

Since August 2010, every query typed into Yahoo Search has returned results supplied by Microsoft Bing. That arrangement effectively ends today: Yahoo has rebuilt its search engine around Scout, the AI answer engine it launched in beta in January, and is deploying the assistant across its entire portfolio of services for roughly 700 million users.

Eric Feng, senior vice president and general manager of the Yahoo Research Group, calls it "truly the biggest update that we've made to Yahoo search in years."

How does the new interface work?

The redesign begins with a single input field and a choice directly beneath it: Search or Scout. Search builds a conventional results page mixing quick facts, links and short AI summaries of news. Scout opens a conversation with the AI, which cites its sources with inline links. A switch at the top of the window, which Yahoo calls Pivot Search, lets users flip between the two views of the same query. Follow-up questions and items marked with the Scout icon also trigger the pivot.

Feng describes the result as AI and search fused into one experience, letting users "move seamlessly between those two types of experiences."

Under the hood, Scout runs on Yahoo's knowledge graph of people, places and things, powered by Bing and Anthropic's Claude. Since the January beta, Feng says Yahoo has cut Scout's response time in half and replaced the single Claude model with several third-party models, including Google's Gemini, each assigned to the task it performs best.

What does 3 billion responses teach a search engine?

Yahoo distilled the redesign from a beta of nearly 10 months and roughly 3 billion Scout responses. The core principle: the query itself should determine the page layout — cards, links, an AI explanation, or a measured mix.

Search for the Chicago Bears and the top of the page fills with glanceable facts: the last game, the next one, the coach. Below sit news stories with short "AI takeaways," shopping links and follow-up questions. Search for Netflix and Yahoo assumes navigational intent; the AI explanation is present, as Feng puts it, "but look how far down we've slotted it." Ask how to calculate compound interest and the explanation leads instead.

"Right now the users often need to understand the answer before they ask the question, which is strange," Feng says.

Google is converging on similar conclusions. According to Search Engine Roundtable, its AI Overviews for brand searches moved to the right-hand column on desktop in the U.S. on November 2, and some summaries now open to full length with a chat box beneath. Google, however, keeps rearranging AI elements on a page originally built for blue links, while Yahoo's layout was designed around them.

Where else does Scout appear?

Scout now extends well beyond the search box:

• Yahoo News and Yahoo Sports: a floating button opens a Scout chat window with questions tailored to the story, supporting voice as well as text. In Sports, it knows which teams a user follows.
• Yahoo Finance: Scout docks on the right side of the page and takes agent-style actions, such as adding Nvidia's earnings date to a calendar or placing Shopify into a watchlist.
• Firefox: Scout now ships inside Mozilla's browser — the first deal of its kind for Yahoo's AI chat, analogous to Gemini in Chrome and Copilot in Edge.

Scout also keeps per-service memories. Interest in Nvidia on Yahoo Finance, for example, is recorded and used there. Yahoo is examining whether memories should carry across services, a step that raises privacy questions. Feng notes users can control and disable the memories: "We want to give users complete control over their data."

Yahoo worked with ElevenLabs on an interruptible voice, including an option cloned from cofounder Jerry Yang — which, after enough conversation, begins to yodel, a nod to the company's famous sound trademark.

Who pays, and does it matter?

Scout's models are rented, so Yahoo monetizes through advertising. CEO Jim Lanzone says the goal is to keep Scout free for everyone. "Maybe one day we'll also have a paid tier," he said, "but free search is extremely important."

Yahoo ranks third in search behind Microsoft, with both far behind Google. Feng points out that shifting market share by a single point means billions in revenue and shareholder value. Whether the redesign achieves that remains unproven — but for 700 million users, a free AI embedded in services they already use gives the revamped Yahoo a credible opening.
