NotebookLM edges out Perplexity Labs on user ratings (4.7 vs 4.4 out of 5), though both remain solid choices depending on your priorities. Both NotebookLM and Perplexity Labs offer free plans, so you can test both before committing. NotebookLM tends to be favoured by students and lawyers, while Perplexity Labs is more popular with programmers and startups.
NotebookLM and Perplexity Labs are frequently weighed against each other — both sit in the research tools space, but they solve the problem from different angles. NotebookLM is best known for multi-source chat, whereas Perplexity Labs stands out for multi-model testing. On aggregate user ratings NotebookLM holds a slight edge (4.7/5 vs 4.4/5), though that gap rarely decides the match on its own.
Where NotebookLM pulls clearly ahead is uploading research papers and asking questions across all of them. A frequent plus in reviews: Zero hallucination on your documents. Perplexity Labs, by contrast, is the stronger choice for testing new Perplexity AI capabilities before general release. In its favour: Completely free, no API keys needed. The feature checklists overlap, but the day-to-day experience does not.
NotebookLM is the best tool for grounded document Q&A — the source citation model makes it significantly more reliable than ChatGPT for factual questions about specific documents. Perplexity Labs is most valuable for power users and developers who want to stay at the frontier of Perplexity's capabilities. Bottom line: the "better" tool here is the one that fits the work you do most.
Choose NotebookLM if you are focused on students, researchers, and knowledge workers who need to deeply understand specific documents — getting cited, verifiable answers from their own materials rather than AI-generated responses that may hallucinate, or if a big part of your week goes to getting cited answers that point to the exact source passage. Its free tier also lets you validate the fit before paying.
Choose Perplexity Labs if your priority is perplexity Pro users and AI enthusiasts who want early access to experimental features and new capabilities before they're widely released, especially for experimenting with image generation features in Perplexity's ecosystem. A free plan is available, so you can trial the workflow at zero cost first.
In day-to-day use, NotebookLM feels strongest at uploading research papers and asking questions across all of them, while Perplexity Labs is more at home with testing new Perplexity AI capabilities before general release.
Learning curve is worth weighing. NotebookLM has a known trade-off — Only works with your uploaded sources. On Perplexity Labs's side: No persistent conversation history. Whichever one slots into your current stack with the least friction tends to win in the long run.
Both tools offer a free plan, so you can trial each side by side before spending anything. Paid plans start at $19.99/mo (Google One AI Premium) for NotebookLM (NotebookLM Plus) and $20/mo for Perplexity Labs (Included with Perplexity Pro), making NotebookLM the cheaper entry point at $19.99/mo (Google One AI Premium) versus $20/mo. The extra spend on Perplexity Labs only pays off if you need what its higher tier unlocks.
