NotebookLM supports a wide range of languages to serve global users. Language support applies to both the platform interface and AI-generated content such as summaries, responses, podcasts, and audio overviews. Google regularly expands language availability, so more options are frequently added to improve accessibility for international users.

NotebookLM Supported Languages in 2026

As of 2026, NotebookLM supports over 80 languages across the globe. According to recent updates from Google's official AI resource hub , major widely used languages include English, Spanish, French, German, Italian, simplified and traditional Chinese, Japanese, Korean, Hindi, Arabic, Portuguese, Russian, Persian, Dutch, Swedish, and Polish.

This broad language support allows users from different regions to use NotebookLM comfortably for research, learning, and daily work.

Can NotebookLM Read Other Languages?

Yes, NotebookLM can still read and understand content written in other languages even after you set your preferred interface or output language. It can fully parse uploaded documents, articles, and study materials in any supported language, regardless of the display language or output language you have selected.

This means you can upload foreign-language files while keeping the UI in your native language and receiving summaries in your target language, making NotebookLM highly effective for cross-language research, multilingual learning, and reviewing international documents without extra translation work.

How to Switch Language in NotebookLM Interface?

Many users want to use NotebookLM with a more familiar navigation experience by switching the interface language. Unlike output language, which controls AI-generated content, the NotebookLM interface language determines the display text of menus, buttons, labels, and on-screen options.

Since NotebookLM is connected with your Google Account, changing its interface language requires adjusting your Google Account language settings. This change applies across most Google services and ensures a consistent experience.

Follow these simple steps to switch the NotebookLM interface language:

First, sign in to your Google Account and go to your account settings. Find the Personal Info section and locate the Language settings under General Preferences for the Web.

If the interface does not update immediately, try clearing your browser cache or logging out and back into NotebookLM. In most cases, the new language settings will take effect within a few seconds.

Another quick method is to adjust the language settings in your Chrome profile where you're signed into your Google Account. This change will also sync and affect the display language of the NotebookLM interface.

How to Change Output Language in NotebookLM?

It's important to note that interface language and output language in NotebookLM are separate settings---changing one will not automatically update the other. The interface language controls your display menus, while the output language determines the language of AI-generated content.

Changing the output language lets you control what language NotebookLM uses for summaries, chat responses, notes, and audio overviews.

Here's how to do it:

  • Step 1: Access the Output Language Settings

    Open your notebook in NotebookLM. Click the Settings (gear) icon in the top-right corner, then locate the Output Language section.

    After saving, all new AI-generated content will appear in your chosen language.
