Perplexity

NotebookLM and Perplexity both help with research, but they solve different problems. NotebookLM is strongest when you bring your own source material. Perplexity is strongest when you need to explore the web and discover sources. This matters because “AI research” can mean two very different workflows.

Used carelessly, it can still lead to weak conclusions if you do not check the sources, dates, context, and assumptions behind the summary. Quick Answer Use Perplexity by starting with a focused research question, asking for structured comparisons, opening the cited sources, checking freshness and reliability, asking follow-up questions, and turning verified findings into a final summary. ...
