Our verdict: NotebookLM excels at audio overviews, but Gemini-only lock-in and limited file exports hold it back.

  • G2 rates NotebookLM 4.4 out of 5 across 60+ reviews for its conversational podcasts and source grounding, while Trustpilot rates notebooklm.google 2.5 out of 5 across 35+ reviews (with 48% one-star ratings).
  • The most repeated complaints are Gemini-only answers, inability to use Claude or GPT on uploaded materials, and having to pay $4.99 to $199.99 a month for Google AI tiers just to raise usage caps.
  • Zemith Plus costs $15.99/mo and combines a 50-source Study Library (audio podcasts, quizzes, flashcards, mind maps) with GPT, Claude, Gemini, Grok, live Deep Research, and downloadable Word, PowerPoint, Excel, and PDF files.

These are the questions people ask about NotebookLM reviews.

Is NotebookLM free to use in 2026?

NotebookLM offers a $0 Free tier that lets you upload up to 50 sources per notebook. However, Free tier users face strict daily limits on generating Audio Overviews, and increasing those limits requires subscribing to Google AI Pro ($19.99/mo) or Google AI Ultra ($99.99–$199.99/mo).

Can I switch AI models or use Claude in NotebookLM?

No. NotebookLM is strictly limited to Google's Gemini models. You cannot test your uploaded documents against Anthropic Claude, OpenAI GPT, xAI Grok, or DeepSeek within NotebookLM. Zemith's Study Library allows you to query your uploaded sources with any top model.

How does Zemith Study Library compare to NotebookLM Audio Overviews?

Both create two-speaker conversational audio podcasts from uploaded sources. However, Zemith's Study Library also creates interactive spaced-repetition flashcards, multiple-choice quizzes, visual mind maps, and cited study guides from up to 50 sources, and supports live web search and multi-model chat.

Can NotebookLM export Word, PowerPoint, or Excel files?

Partly. Gemini Notebook exports reports and notes to Google Docs, data tables to Google Sheets, and slide decks to PowerPoint (.pptx), but we found no way to export finished Word (.docx) or Excel (.xlsx) files directly. Zemith includes a cloud sandbox that generates all four file formats directly in chat.

What do reviewers complain about most in NotebookLM reviews?

Reviewers on G2 and Trustpilot most frequently complain about strict daily Audio Overview caps on the free tier, Gemini-only answers when documents lack context, limited file exports, and inability to query Claude or GPT models.
