Both Perplexity and NotebookLM still offer a free tier, but the better models, higher usage, and team features sit on paid plans.
Both have a free path, but the paid comparison works differently. Perplexity publishes Pro at $20, while NotebookLM upgrades ride Google AI or Workspace bundles, so the cheaper answer depends on whether NotebookLM is piggybacking on spend the company already has.
Yes. A split-seat setup makes sense when one tool covers the default workflow and the other handles the narrower job it clearly does better.
Perplexity is the better buy for live web research, cited answers, and fast exploration across changing information. NotebookLM is the better buy for grounded synthesis from a known source pack or internal document set.
Choose based on whether the core workflow starts from the web or from controlled source collections.
Perplexity is the better buy for live web research, cited answers, and fast exploration across changing information. NotebookLM is the better buy for grounded synthesis from a known source pack or internal document set.
Perplexity has published paid plans starting at $20/month (Pro), and a $0 or included entry is also listed; compare that entry's allowance before treating it as a full free seat.
NotebookLM does not publish a fully comparable self-serve paid starting price, so budgeting still requires a manual quote or plan-specific review.
The published pricing is approximate because at least one side relies on quote-only or incomplete monthly pricing.
