Can I use NotebookLM offline?
No. NotebookLM requires internet connectivity. The AI processing happens on Google's servers, so no queries or Audio Overview generation work offline. Audio Overviews can be downloaded for offline listening once generated.
In more detail
NotebookLM is a cloud-based service; all source processing, chat queries, and Studio artifact generation happen server-side and require internet. Audio Overviews can be downloaded after generation and played offline through your device's audio app. Sources are stored in Google's cloud; the mobile apps don't cache full sources for offline use. For offline-first research workflows, consider local-first PKM tools (Obsidian, Anytype, Logseq) — at the cost of NotebookLM's AI capabilities.
