Expert techniques to get the best results from Perplexity
Perplexity always cites, but you can ask it to 'prioritize peer-reviewed sources' or 'only use sources from the last 6 months' to refine quality.
Switch to Academic, YouTube, Reddit, or News focus modes to restrict sources to the most relevant type for your query.
Start broad ('What are the main approaches to X?') then drill down ('Explain approach 2 in detail with examples'). Perplexity maintains context.
