Microsoft has confirmed that Bing's Copilot Search now offers two distinct AI experiences, AI Mode and AI Overview. AI Overview adds AI-generated summaries alongside regular search results, while AI Mode offers a conversational experience for researching topics in depth; both are shipped features, not announcements.
Why it matters
Splitting one AI search product into named modes signals that search engines are separating quick summaries from extended, conversational research as distinct user tasks. Microsoft said the new names exist to help users understand the two experiences, and the underlying Copilot technology is unchanged.
Microsoft's own documentation describes two AI experiences, AI Mode and AI Overview, with the Copilot underlying technology unchanged, and the source gives no benchmark or usage figures for either. The FAQ and walkthrough are the only documented evidence, so performance claims for the split remain unverified.
The players
Microsoft
Microsoft operates Bing and its Copilot AI stack, which powers both AI Mode and AI Overview in its search product.
Search Engine Watch
Search Engine Watch is a search-industry news site that spotted Microsoft's FAQ describing the two Bing AI experiences.
The details
AI Overview attaches AI-generated summaries to the regular list of search results, so a user gets a condensed answer without leaving the results page. AI Mode is a conversational layer where a user asks follow-up questions and explores a topic in depth. Responses in AI Mode draw on information from the web and include source links, so a user can check where claims originate. Microsoft's Search with AI page walks users through opening AI Mode from search results, viewing full and media results, asking follow-ups, and checking sources.
Timeline
Microsoft's Search with AI FAQ, which defines the two experiences, was spotted by Search Engine Watch on or around 2026-11-01.
The Tech Race
Microsoft is packaging its Copilot technology into separately named Bing modes, a product-positioning move within the competition among search engines to put AI at the center of results. The source does not place this against any named rival product or roadmap milestone.
Users of Bing can now choose between a quick AI-generated summary alongside results (AI Overview) and a conversational research mode (AI Mode) that cites web sources. The source does not state a rollout timeline or regional availability beyond the Bing Android app showing AI Mode branding.
The takeaway
Watch whether Microsoft keeps AI Mode and AI Overview as separate products or folds them back together as usage data comes in. Users who want to test the difference can open AI Mode from Bing search results and compare its source-linked answers against the AI Overview summary on the same query.
