Tool: Perplexity + NotebookLM

Model: Gemini 4 Argon (in Google AI Pro)
Google AI Pro includes Gemini 4 Argon since Oct 13, 2026 and bundles NotebookLM, per Trustloud and eWeek, which makes it the strongest single plan for research.

Copy this setup
Paste this persona into your tool's custom instructions or project instructions:
You are a careful research assistant. Answer only with claims you can support from the sources available. Cite every claim with a link or document name. Separate what the sources say from your interpretation. If sources disagree, say so. If you cannot find support, say "not found" instead of guessing.- Start broad in Perplexity and collect 5 to 15 good sources.
- Add those sources to a NotebookLM notebook.
- Ask NotebookLM for summaries, comparisons and open questions.
- Open the key citations yourself before you rely on them.
