In short. Copilot supports documented personal-account languages, while consumer search access also depends on the service and its regional availability.

Definition: Copilot language support is Microsoft's documented coverage of languages for prompts and responses in its AI assistant. Consumer search availability also depends on the service and the market where it is accessed.

Key facts

As of 17 October 2026, Microsoft's Copilot language support documentation lists 43 language entries for personal Microsoft accounts and describes availability across more than 170 markets, with regional exceptions.
Bing's Copilot Search launch announcement, dated 4 April 2025, describes worldwide availability except Russia and China.
Microsoft's Copilot Search FAQ identifies Copilot Search in Bing as web search for individuals, accessible through a browser without a Microsoft Copilot license.

Which languages are supported for personal accounts?

Microsoft's supported-languages page, labeled September 2026, separates personal Microsoft accounts from work or school accounts. Its personal-account list covers Arabic, Bulgarian, Croatian, Catalan, Czech, Danish, Dutch, Estonian, Finnish, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Polish, Romanian, Russian, Slovak, Slovenian, Swedish, Thai, Turkish, Ukrainian, Vietnamese and Welsh.

The same list specifies Simplified and Traditional Chinese; United Kingdom and United States English; France and Canada French; Brazil and Portugal Portuguese; and Spanish alongside Spanish (Mexico). It also specifies Norwegian (Bokmål) and Serbian (Latin script). These labels give a website owner a more precise reference than a general claim of multilingual support.

The page maintains a separate list for Copilot Voice, the spoken-conversation feature. A check of written consumer searches uses the personal-account prompts-and-responses list.

How does market availability differ between services?

Microsoft's support documentation names China, excluding Hong Kong SAR, and embargoed markets as places where Copilot is unavailable or unsupported. It also states that new features can reach regions and languages at different times.

Language support and territorial access are separate checks. Russian and Chinese appear in the personal-account language list, while the service documentation also describes geographic restrictions.

For Copilot Search in Bing, the Bing launch post supplies its own geographic statement: worldwide except Russia and China. This statement belongs to the launch date. The opened documentation supplies no current country-by-country matrix linking each consumer search feature to each supported language.

How can consumer search availability be checked?

Microsoft's Search FAQ distinguishes Copilot Search in Bing from Microsoft Copilot Search for work and school, which searches organizational content. That distinction matters when choosing a language or availability reference for a public website.

The Bing announcement provides this entry address:

https://aka.ms/CopilotSearchinBing

It also describes access through Bing's navigation bar and the Bing mobile app. A recorded availability check can identify that surface, the access country and the query language, keeping the observation tied to the service tested.

FAQ

Does a translated interface confirm support for my prompt language?

Microsoft's language documentation says an unsupported-language message can appear even when the interface is translated into that language. Check the personal-account list for the language you use or request.

Do I need a paid Copilot license to search the web in Bing?

Microsoft's Search FAQ says Copilot Search in Bing requires no Microsoft Copilot license. You access it through a web browser.
