How many languages does NotebookLM support?
One sentence: NotebookLM works in 80+ languages for chat and Audio Overviews, with a few newer features like Cinematic video and length control currently limited to English.
NotebookLM supports 80+ languages for chat responses and Audio Overviews. Video Overviews' Explainer format supports 50+ languages. A handful of newer features, the audio length selector and Interactive mode among them, are currently English-only and expand over time.
Setting your language
Go to Settings (top right of a notebook) and choose an Output Language. This sets the language for chat answers and Studio-generated content in that notebook, independent of the language your source documents are written in. You can upload English sources and generate a Spanish Audio Overview from them, or the reverse.
Where full support exists
- Chat, answering questions in your chosen language regardless of source language.
- Audio Overviews, generating full podcast-style discussions in 80+ languages.
- Explainer-format Video Overviews, in 50+ languages.
- Reports like study guides and briefing docs, generated in over 130 languages.
Where support is currently narrower
A few newer or more experimental features launch in English first and expand later: the Shorter/Default/Longer length control for Audio Overviews, Interactive mode's voice question feature, and the Cinematic and Short Video Overview formats are all English-only as of this writing. This is a common pattern with NotebookLM's rollout, features debut in English and gain broader language support in subsequent updates, so check the Audio and Video guides for current specifics.
Forcing a language explicitly
Beyond the Settings toggle, you can also instruct language directly in a customize prompt, useful for language learners or anyone who wants extra certainty: "This episode will ONLY be in Portuguese, including all technical terms explained in Portuguese rather than switching to English." More on this pattern in Audio Overview prompts.
