Perplexity vs Google NotebookLM

Both answer questions with AI research, but from different sources. Perplexity searches the open web with citations; Google NotebookLM works exclusively with documents the user uploads.

When to pick which

Choose Perplexity if open web search with citations and deeper research reports is the priority; Pro and Max use dynamic weekly and monthly limits, Education Pro costs $10 a month, and Enterprise Pro includes 500 while Enterprise Max includes 15,000 credits per month with no rollover. Choose NotebookLM if you want to query only your own sources and turn them into audio, video, study, and research outputs; it is billed only through regional Google plans, with Plus allowing 200 notebooks with 100 sources each and 3 deep-research tasks a day, and Pro extending that to 500 notebooks with 300 sources each and 20 deep-research tasks a day.

Differences at a glance

Perplexity answers questions from the open web with citations; NotebookLM stays strictly limited to sources the user has uploaded.
NotebookLM also turns those own sources into audio and video outputs (such as podcast-style summaries), a feature Perplexity does not offer in this form.
Perplexity's Pro/Max tiers count in dynamic weekly and monthly limits rather than fixed allowances; NotebookLM instead counts in fixed numbers: notebooks, sources per notebook, and deep-research tasks per day.
NotebookLM is not sold on its own but only bundled into Google's AI Plus, Pro, or Ultra subscriptions; Perplexity instead has its own Pro, Max, and Education plans.
