Frequently Asked Questions

Is Perplexity better than Google?

Perplexity is better than Google when you want a direct answer with citations rather than a list of links to read. For navigating to websites, finding local businesses, or general browsing, Google is still better. Perplexity excels for research questions where you want a synthesized answer.

Is NotebookLM free?

NotebookLM is free for all Google users at notebooklm.google.com. NotebookLM Plus is available through Google One AI Premium ($19.99/month) with higher usage limits.

What is the difference between Perplexity and NotebookLM?
