A practical guide

Why is my AI search in a different language?

Practical reasons your AI search answers appear in another language, how Google decides result languages, and step-by-step ways to test and fix it without guessing.

By My AI Search Report23 October 2026

Short answer: Google can show results and AI summaries in a different language based on several signals, including the language you typed, your Google display language, your device languages, your location, and whether helpful content exists in another language. AI Overviews are part of Google Search and follow its availability by country and language; you can’t turn this feature off, but you can use the Web filter to see only links. Use Google’s Results Language Filter and related settings to narrow languages when you test. See Google’s official guidance (https://support.google.com/websearch/answer/13511324 and https://support.google.com/websearch/answer/14901683).

How Google decides the language you see

Google explicitly lists the signals it uses to guess the most helpful language(s) for your results:

The language you typed your query in. This can suggest you want results beyond your current settings.
Whether content in another language would be more helpful, or if there isn’t enough information in your query’s language.
Your Google display language (for buttons and labels) which can influence, but doesn’t lock, result languages.
Your device or computer languages, which can inform Google’s choice.
Your location, which helps disambiguate terms and may influence languages shown; you can change location.
What website owners declare for multilingual sites (for example, language targeting signals) to help Google show the right language to the right people.

All of the above are from Google’s documentation (https://support.google.com/websearch/answer/13511324).

AI Overviews, availability and what you can (and can’t) change

AI Overviews appear when Google’s systems think generative AI will help summarize or connect information. They’re a core part of Search and can’t be turned off, but you can switch to the Web filter to see only text-based links without features like AI Overviews (https://support.google.com/websearch/answer/14901683). Availability of AI Overviews depends on supported countries, territories and languages; Google maintains the current list (https://support.google.com/websearch/answer/14901683). If your region/language isn’t supported, you may see a different experience from other testers.

Fix or test language behavior in Google Search

Use the Results Language Filter

On a results page, click Tools → Any language → select your preferred language(s). If the only selected language is English, the filter may not display.
Or open Search settings → Results Language Filter → choose one or more languages → Confirm.
Filters mainly apply to web results. Some features (for example, Knowledge Graph and Top Stories) can’t change language, and filters may not work if Google can’t detect a page’s language (for example, mixed-language pages). All per Google’s documentation (https://support.google.com/websearch/answer/13511324).

Check display language, device languages and location

Google display language: Set your preferred interface language; it helps but doesn’t force result language (https://support.google.com/websearch/answer/13511324).
Device/computer languages: Ensure your OS/browser language preferences reflect what you want (Google can use them).
Location: Google finds it automatically and lets you change it. An incorrect location can nudge results toward another language (https://support.google.com/websearch/answer/13511324).

Switch to Web-only view if AI Overviews are confusing

After a search, select the Web filter to display only text links without AI Overviews (https://support.google.com/websearch/answer/14901683).

Output language versus source language

Two separate things can be happening:

Interface language: Labels, buttons and some UI strings follow your Google display language.
Result and summary language: Google may show content or summaries in a different language if it believes that will be more helpful, or if there’s limited high-quality content in your query’s language (https://support.google.com/websearch/answer/13511324). Language filters primarily affect web links; some search features can’t change language (https://support.google.com/websearch/answer/13511324). AI Overviews are integrated with Search and follow its regional and language availability (https://support.google.com/websearch/answer/14901683).

How to run a clean comparison or audit

When you compare providers or repeat tests, lock down variables so you’re measuring language behavior and not environment drift:

Fix your interface language, device language list, and location. State what each is.
Use the same neutral test queries without language hints (avoid adding “in English,” brand names known in one market, or transliterated terms).
Note signed-in state, browser profile, and whether Results Language Filter is set.
Record whether you used the Web filter or the default view.

Compact checklist

Confirm your Google display language and your device/browser language list.
Check your location setting matches your intended region.
On a results page, set Tools → Any language to your target language(s).
If AI Overviews are confusing, switch to the Web filter to view links only.
Retry the same neutral query and note any feature that doesn’t follow filters.
Document all settings when comparing across tests or providers.

FAQ

Can I force AI Overviews to answer in English?
You can’t turn AI Overviews off or force a single language, but you can apply the Results Language Filter for web results and use the Web filter to show links only (https://support.google.com/websearch/answer/14901683 and https://support.google.com/websearch/answer/13511324).

Why are some links or snippets in a different language even after I filter?
Google says language filters mostly affect web results, and some features can’t change language. Filters may also fail when a page’s language can’t be detected, for example on mixed-language pages (https://support.google.com/websearch/answer/13511324).

Could site settings affect what I see?
Yes. For multilingual sites, owners can indicate language targeting so Google knows which language to show to which people (https://support.google.com/websearch/answer/13511324). That signal can influence which versions you’re shown.
