Full review →What is NotebookLM?
NotebookLM is Google's AI research tool that turns your uploaded documents into an interactive knowledge base. Upload PDFs, Google Docs, YouTube videos, or web links — then chat with them, generate study guides, create timelines, and produce Audio Overviews (AI podcast summaries). It only answers based on your sources, making it highly reliable for research. The free tier supports 25 notebooks with 50 sources each.
What is Claude?
Claude is Anthropic's AI assistant, known for its 200K token context window (handling entire books), industry-leading accuracy, and strong coding performance. It can process PDFs, images, and large documents directly. Unlike NotebookLM, Claude can answer from its full training knowledge base and browse the web — not just from sources you upload.
The key distinction: your sources vs all knowledge
NotebookLM's defining feature is also its limitation: it only answers from what you upload. This eliminates hallucinations about external facts but means it cannot help you beyond your source set. Claude draws on its full training, live web access, and any files you share — making it more versatile but less constrained to specific sources.
| Feature | NotebookLM | Claude |
|---|---|---|
| Knowledge source | Your uploads only | Training + files + web search |
| Context window | Up to 500 pages per source | 200K tokens (~150K words) |
| Audio Overview | ✅ AI podcast of your docs | ❌ Not available |
| Source citations | ✅ Every answer cited | Partial (with web search) |
| Coding ability | Basic | ✅ Industry-leading |
| Free tier | ✅ Generous | ✅ Limited daily usage |

View Claude →Frequently asked questions
Is NotebookLM better than Claude for research?
For research on a specific set of documents, NotebookLM is better — it cites every answer and never hallucinates facts outside your sources. For broader research requiring general knowledge, web search, and complex analysis, Claude is stronger.
Can Claude do what NotebookLM does?
Claude can analyse uploaded documents and answer questions about them, but it lacks NotebookLM's Audio Overview feature, multi-source notebook management, and guaranteed source-only answers. NotebookLM is purpose-built for document research; Claude is a general-purpose AI.
Is NotebookLM free?
Yes — the core experience is free with 25 notebooks and 50 sources each. NotebookLM Plus (via Google One AI Premium at $19.99/mo) adds more notebooks, higher source limits, and enhanced Audio Overview customisation.
