Pick Claude for a general assistant that writes, codes and builds files: Pro is $20/mo billed monthly or $17/mo billed annually. Pick NotebookLM for answers and study aids grounded in your own documents, free for up to 50 sources per notebook. Google's plans page shows no USD prices for the paid tiers.
We wrote this from our own profiles of both tools, verified on September 30 (Claude) and October 1 (NotebookLM, now Gemini Notebook); we ran no benchmarks, used no third-party tests and took no vendor payments.
Pick Claude if you want one assistant for writing, coding, web search and building files, and you accept that every plan, including the free one, has usage limits. Pick NotebookLM (now called Gemini Notebook) if your work is a pile of documents you want answers, audio recaps, flashcards and reports from, and a free tier with up to 50 sources per notebook is enough to start. The price comparison is lopsided by what is published: Claude lists Pro at $20/mo, while Google's plans page shows no USD prices for the paid Google AI tiers.
Based on our profiles of both tools: Claude verified on September 30 and NotebookLM (Gemini Notebook) verified on October 1. No benchmarks were run for this pair.

Both have a free tier, so you can start at $0 with either. Beyond that only Claude has a published price: Pro is $20/mo billed monthly or $17/mo billed annually. NotebookLM's paid options are Google AI Plus, Pro and Ultra, and their USD prices are not shown on the Gemini Notebook plans page, so we cannot rank the paid tiers on cost.
Claude is a general assistant: it writes, codes, searches the web and builds files. NotebookLM answers from the sources you add to a notebook and turns them into Audio Overviews, Video Overviews, Flashcards, Reports and Slides. Pick by whether your starting point is a prompt or a pile of documents.
They count differently. Claude takes up to 20 files per chat at 500 MB each, with PDFs up to 1000 pages. NotebookLM caps sources per notebook: 50 free, 100 on Plus, 300 on Pro and 600 on Ultra. NotebookLM's file types and size limits are not confirmed in our profile.
Google says organization and school data is never used to train it, and individual data is used only if you submit feedback. Claude differs by plan: consumer Free, Pro and Max inputs may be used for training unless you opt out, while Team and Enterprise are off by default. NotebookLM's data retention period is not stated.
Not confirmed. We found no API on the NotebookLM pages we checked. Claude has a developer API on Claude Platform, billed per token and separate from the chat plans.
Google's pages now call it Gemini Notebook, formerly NotebookLM. We keep the old name in this comparison because it is the one most people search for.
